Introduction

The History of Süd-Chemie

The Beginning

Süd-Chemie’s initial operations were launched in 1857 by one of the world‘s leading chemists of the time, Justus von Liebig.

The Munich-based company began producing mineral fertilisers in 1906. It subsequently branched out into the chemistry of surface reactions, producing highly active bleaching earth. In 1959, a joint venture with Girdler Catalyst in Louisville, Kentucky, was formed. Production of Girdler catalysts in Germany started in 1961.

Going Global

After 15 years of partnership, Süd-Chemie took over Girdler Catalyst‘s operations in their entirety, including the company‘s share in the Japanese Nissan Girdler Catalyst (NGC).

In 1976, Süd-Chemie acquired the Louisville-based Catalyst and Chemicals Inc. (CCI), including partnerships with CCIL, India and CCIFE, Japan. US Girdler and CCI catalyst operations were then merged to form United Catalyst Inc. (UCI).

In the Asia-Pacific region, production of CCI catalysts for Indonesia has been handled by PT-Kujang – United Catalysts since the mid-eighties. In 1981, African Catalyst started manufacturing oligom-erisation catalysts in Sasolburg, South Africa. Süd-Chemie has been producing zeolite catalysts via Syncat/SC Zeolites in South Africa since 1991.

In 1990, Süd-Chemie purchased Houdry process and catalyst manufacturing technology operations from Air Product and Chemical Inc., USA. The Houdry process is used for dehydrogenation in the production of octane boosters, and for dealkylation in the production of pentene. Today, process technology is handled by ABB Lummus Global Inc.

7

In 1997, Süd-Chemie acquired the Italian Montecatini Technology, which was to continue under the new name of Süd-Chemie MT S.r.l. The company‘s catalysts are mainly used for oxychlorination in fluid or fixed-bed operation and in the production of terephthalic acid for PET, resins and polyester fibres.

Süd-Chemie acquired Prototec Inc., USA in 1992, with a view to expanding its operations in the environmental sector. Prototec special-ises in catalysts and equipment for air purification in food preparation and other industries. Today, Süd-Chemie’s environmental solutions include catalysts for virtually all types of air and gas purification.

In 2003, Süd-Chemie acquired Scientific Design, Little Ferry, USA, as part of a joint venture with the major Saudi Arabian manufacturer SABIC. Scientific Design specialises in processes involved in the production of ethylene oxide.

The global identity of all of these companies is reflected in the common name and slogan: Süd-Chemie – Creating Performance Technology®

Shapes make the Difference

All of Süd-Chemie‘s catalysts are available in a wide variety of different shapes and sizes, so that the user can always select the opti-mum catalytic technology to suit his needs. There are basically two different types of catalyst:

• Precipitated catalysts

• Carrier catalysts

Precipitated catalysts are of identical chemical composition throughout the entire particle, whereas in a carrier catalyst, the active component is impregnated on an inert carrier.

Typical shapes include:

• Tablets

• Rings

• Ribbed rings

• Multiholed rings

• Extrusions

• Pellets

• Spheres

• Monolithic structures

• Saddles

• Foams (ceramic and metallic)

• Wire mesh

• Wall flow filters

• Fibre mats

• Screens

• Flakes

• Granules

• Powder

Introduction

Tablets

A variety of tablet sizes can be produced, depending on the catalyst formulation and the intended application. The most common sizes range from 3 x 3 mm to 9 x 9 mm. Most of our tablets are domed, ensuring less dust formation thanks to more stable edges and a more uniform and dense loading.

Smaller tablets generally have greater activity, but a higher pressure drop.

Extrusions

Extrusion is the preferred method for precipitated catalysts. The key types of extrusions are:

• Plain extrusion

• Ribbed extrusion

• TRIAX extrusion

• CDS extrusion

CDS extrusion creates the most sophisticated extruded shape. CDS stands for Computer Designed Shape, and represents an optimum combination of physical strength, activity, poison resistance and pressure drop. For this reason, Süd-Chemie offers a wide range of catalysts in this shape.

Introduction

10

Rings

Rings are the ideal shape for carrier catalysts. The carrier is a strong inert material in a wide variety of ring shapes, such as:

• Raschig ring

• Ribbed ring (RR)

• 3-holed ring (THS)

• 6-holed ring (gutling gun, GG)

• 10-holed ring (low differential pressure, LDP shape)

• Spoked-wheel (EW shape)

Spheres

Spherical catalysts can include both palletised and tabletted, precipi-tated and carrier catalysts. They can be as small as 1 mm and as large as 75 mm.

Honeycombs and Foams

Where an application is sensitive to pressure drop, as is the case for ambient pressure operations, or where a high space velocity is needed, honeycombs and foams - whether ceramic or metallic - are the optimum shape.

Honeycombs and similar shapes form the basis of almost all catalysts used for air purification and for the reformer upstream of fuel cells.

Introduction

11

Other Shapes

Some catalysts are available in the form of flakes or irregular granules. For application in a fluidised bed or in liquid phase, powder is the ideal shape.

Please note that the shapes and sizes listed in this catalogue represent the standard for the respective product. Please contact our sales division for information on non-standard dimensions.

Reduced and Stabilised Catalysts

Most catalysts consist of one or more metal oxides. Most of Süd-Chemie’s catalysts can be supplied in any of the following formats:

• oxidic

• reduced and dry stabilised (RS version)

• reduced and submerged in an organic liquid (R version)

The RS and R versions are safe to transport and ready to use with only a short start-up time.

ActiSorb® Catalyst Series

Süd-Chemie developed the ActiSorb® series of catalysts and adsorbents for the purification of almost all hydrocarbon feedstocks. This purification is normally a combination of a reaction using a pre-treatment catalyst, i.e. hydrogenation, followed by adsorption with the ActiSorb® adsorbent.

The following table gives a general overview of the different families of ActiSorb® materials.

Sulphur Removal

Sulphur in the form of organic compounds can be removed either as such or by hydrogenation to H2S followed by adsorption of the latter.

The ActiSorb® S 7 catalyst is recommended for the removal of H2S, mercaptans, disulphides and thiophens in hydrocarbon feedstreams, ranging from naphtha to middle distillates. The achieved purity is less than 0.1 ppm wt. sulphur.

Hydrodesulphurisation

The standard catalysts for the hydrogenation of organic sulphur compounds in hydrocarbon feedstocks are the cobalt-molybdenum-type catalysts from the HDMax 200 series. These catalysts are used in both liquid and gas phase for all types of hydrocarbons, such as naphtha, LPG, natural gas and off-gases. For the hydrogenation of organic nitrogen compounds and/or olefin saturation, our nickel-molybdenum-based HDMax 310 catalyst is recommended.

H2S Removal

The ActiSorb® S series of ZnO based adsorbents is used for the removal of sulphur components such as hydrogen sulphide, mer-captans and COS from hydrocarbon feedstreams. ActiSorb® S 2 is the perfect solution when operating at high space velocities and elevated temperatures, while ActiSorb® S 3 is recommended in applications with lower space velocities and higher inlet sulphur concentrations. The maximum bulk density catalyst ActiSorb® S 1 is ideal in applications where the feed contains high inlet sulphur concentrations, and where maximum sulphur pick-up per loaded unit volume is required.

In some cases, it is necessary to remove the sulphur to a level below 10 ppb H2S. ActiSorb® S 6, a copper-promoted zinc oxide, is placed in the bottom of the standard zinc oxide reactor and removes the remaining H2S to a value < 10 ppb H2S under a wide range of operating conditions.

Desulphurisation of natural gas and light hydrocarbon feedstocks is also possible under ambient conditions using activated carbon. G-32J is coconut-shell-based and promoted with copper oxide. It should be noted that propane and C4+ hydrocarbons are absorbed by the activated carbon, thereby minimising the sulphur pickup capa-bility of G-32J.

COS Hydrolysis

The ActiSorb® 410 catalyst selectively promotes the simultaneous hydrolysis of COS and hydrogenation of CS2. HCN is also hydrolysed. The high selectivity of ActiSorb® 410 means that process gases with very high CO concentrations can be treated.

The feed to the COS hydrolysis reactor usually contains nickel and iron carbonyls. These carbonyls decompose on the ActiSorb® 410 catalyst into CO and the respective metals, leading to deactivation of the ActiSorb® 410 catalyst. It is therefore necessary to install a guard reactor with ActiSorb® 400 to decompose any traces of metal carbonyls selectively on the guard catalyst.

COS and Arsine Removal

Refinery feeds and C3 streams from steam crackers often contain both COS and AsH3, and sometimes PH3 traces. CuO catalysts such as ActiSorb® 300 and ActiSorb® 310 are currently used with great suc-cess, mainly to purify propylene. Absorption of poisons can be accom-plished in either the gas or liquid phase. The product purity achieved is normally below the detectable limit. As a result, the selective hydro-genation catalyst installed downstream is perfectly protected and can pursue its basic activity and selectivity.

The consumption of polymerisation catalysts is drastically reduced with a poison guard. Feed polishing prior to polymerisation is therefore extremely valuable for downstream operations.

CO Removal

Various feed-streams contain CO in concentrations of several ppm up to one percent, which has to be removed to levels below 10 ppb. The type of catalyst is chosen according to the feed, e.g. Ni catalysts to methanate CO in hydrogen streams and CuO-catalysts to remove CO from ethylene and nitrogen by adsorption or by catalytic reaction with addition of air/oxygen.

Removal of CO from Hydrogen

In steam cracker plants, the hydrogen typically contains 0.2 - 1% vol. CO, but no CO2. Ideally, CO-methanation should be carried out at the lowest possible temperature. To accomplish this task, we provide an Ru-catalyst for operating temperatures of approximately 170 °C and Ni-catalysts, which must be operated above 200° C to avoid Ni-carbonyl formation.

certain is that illustriously effective cellophane can be especially efficiently produced with specialised K-Catalysts from

Süd-Chemie. As can many other products. Discover the possibilities!

28

Acidic Catalysts

The “K-catalyst” product family is based on the naturally occurring mineral montmorillonite, which is acid-activated to produce the various different K-catalysts. The resulting products are characterised by different acidities, cation exchange capacities and porosities.

Product Description

Our proprietary production procedures result in products with high Brönsted acidity:

• KSF

• KSF/O

• KP 10

or high Lewis acidity:

• K 5

• K 10

• K 20

• K 30

• K 40

Acidic Catalysts

Our broad portfolio of K-Catalysts allows the opportunity to optimise process efficiencies through distinct pore structures, surface areas and acidities. K-Catalysts are all available as powder, and some as granules.

29

Styrene Production

The majority of styrene produced in the world today is made by dehy-drogenation of ethylbenzene (EB) using one of a family of Süd-Chemie STYROMAX® catalysts. These include the following:

STYROMAX® 3 Still the most widely used catalyst in the Ameri-can and European markets. It is very physically rugged and has demonstrated run-lengths of longer than 42 months. STYROMAX® 3 offers an excellent balance of activity and selectivity, while being extremely cost-effective. It can be used at steam/oil levels down as far as 1.15 wt./wt.

STYROMAX® 5 Widely used in Asia, STYROMAX® 5 is very similar to STYROMAX® 3 in terms of perform-ance. It can also be used at all steam/oil levels above 1.15.

STYROMAX® Plus 5 More active and more selective than STYROMAX® 5, this is the most common catalyst in use in Asia. STYROMAX® Plus 5 is commercially tried and tested at steam/oil levels down as far as 1.15 wt./wt. It offers the best combination of selectivity and activity available in the world today.

STYROMAX® 6 Essentially the same performance as STYROMAX® Plus 5. It is physically stronger than STYROMAX® 3 and features an exception-ally low attrition rate. It can also be used at all steam/oil levels above 1.15.

STYROMAX® 7 State-of-the-art catalyst for ultra-low steam/oil operation. Has been extensively tested in adiabatic pilot plants at steam ratios as low a 0.9 wt./wt.

All STYROMAX® catalysts are available in various different sizes and shapes. Standard sizes are 3.0 mm smooth extrusion, 3.5 and 4.5 mm patented ribbed extrusions. Custom sizes and shapes are available upon request.

Steam Cracker Plants

Catalytic selective hydrogenation of acetylenes and dienes in the presence of olefins represents standard procedure for purifying olefin streams in steam cracker plants . High selectivity is required to gain olefins from the hydrogenated acetylenes and dienes while achieving high purity products.

Olefin streams to be catalytically purified may be broken down into:

Front-end systems with C2 gases up to raw gas also containing hy-drogen, methane, CO and sometimes sulphur

Tail-end systems with concentrated ethylene/ethane mixtures and propylene/propane mixtures

C4 and C5 cuts may be selectively hydrogenated or, alternatively, completely saturated. Hydroprocessing of aromatic concentrates such as pyrolysis gasoline or dripolene is also possible.

Front-End Hydrogenation

Sulphur-free Gases

The OleMax 250 family of front-end hydrogenation catalysts is characterised by high selectivity in the hydrogenation of acetylenes and dienes in raw olefin, C3-minus and C2-minus streams. These catalysts are suitable for use in isothermal tubular reactors as well as for adiabatic beds. They are regenerated either by steam/air treatment in situ or with air ex situ.

OleMax 251 is the ideal choice for streams with low and/or fluctuating CO levels. New versions of OleMax 250 series are under development and soon to be introduced to the industry.

C3 Tail-End “Gas Phase” Hydrogenation

The conventional method for the removal of methylacetylene and propadiene (MAPD) from propylene/propane streams is selective hydrogenation over a Pd based catalyst from the OleMax 300 family. The aim is to increase the propylene concentration and to decrease MAPD to below 10 ppm. Typically, purification is performed with a molar ratio of hydrogen to MAPD of between 1:1 and maximum 1.5:1.

The Pd-catalysts are regenerable with steam/air in situ.

C3 Tail-End “Liquid Phase” Hydrogenation

It is common practice in steam cracker plants to hydrogenate the higher olefin streams selectively in liquid phase by means of Pd cata-lysts with a Pd content of 0.1 – 1.0 wt.%, where gas phase hydrogen-ation catalysts typically consist of Pd on alumina in a concentration of only 0.01 – 0.1 wt.% palladium. The temperature range applied varies from 10 – 200° C depending on the carbon number and the pressure of the olefin stream. For C3 cut hydrogenation, the aim is to selectively hydrogenate up to 7% methylacetylene and propadiene in a propylene stream with an increase in propylene and suppression of by-product formation.

C4 Cut Hydrogenation

The steam cracker C4 cut consists of approximately 50 wt.% 1.3-butadiene and 1 wt.% acetylenes in a mixture of butenes and butanes. Purification of this stream necessitates several hydrogenation steps depending upon the further use of the stream.

IntroductionCatalysts for theProduction of Chemicals

A masterpiece only really shines in candlelight

To ensure it stays that way, Süd-Chemie develops and produces catalysts for wax production among other applications. We offer a wide variety of products in the syngas and speciality chemical

sector at the highest quality.

50

Production of Chemicals

Süd-Chemie supplies catalysts for intermediates in the wide-ranging field of performance chemicals. Süd-Chemie produces catalysts for alcohols and manufactures resins, rosins and waxes. It also covers catalysts for caprolactam and nylon products, the catalysts for natu-ral and related products such as vitamins and fragrances, as well as oxidation catalysts. Furthermore all relevant synthesis gas catalysts are covered for the production of ammonia, methanol, carbon monoxide and hydrogen for a variety of applications. Most of the catalysts mentioned in this section are available in the oxidic form als well as in the pre-reduced and stabilised (RS) form.

Production of Ammonia and Methanol

The production of ammonia or methanol involves the use of several key unit operations for which Süd-Chemie supplies catalysts.

These are:

• Feedstock purification

• Prereforming

• Steam reforming

• Secondary reforming

• Autothermal reforming

• CO conversion

• Methanation

• Ammonia synthesis

• Methanol synthesis

51


Prereforming

A prereformer is an adiabatic fixed-bed reactor upstream of the primary reformer. It allows increased flexibility in the choice of feed-stock, increased lifetime of the steam reforming catalyst and tubes, and the option of increasing the overall plant capacity. Furthermore it allows an operation at lower steam/carbon ratios. ReforMax® 100 is a prereforming catalyst designed to handle the entire range of hydrocarbon feedstocks from natural gas up to and including LPGs and naphthas.

Secondary Reforming

The optimum catalyst for an air-blown secondary reformer depends on the design of the burner and the distance between burner tip and top catalyst layer. If hexagonal target bricks are not used, we recom-mend installation of a top layer of ReforMax® 400 GG to serve as an active heat shield. This material is also ideal for a bottom active support layer where extreme short loadings are required and/or high purity inert supports have been used in the past. ReforMax® 400 LDP catalyst is used for the bulk of the reactor loading.

CO Conversion

Most ammonia plants convert CO to CO2 by high-temperature CO conversion followed by low-temperature CO conversion. For special process design, it can be advantageous to combine these two steps to form one isothermal or adiabatic step called „medium-temperature CO conversion“ (MTS).

High-temperature CO Conversion

The HTS catalyst ShiftMax® 120 combines high activity with extremely good physical robustness. In addition, this catalyst is very effective in preventing Fischer-Tropsch by-product formation when operating at low steam conditions.

Fatty Alcohols and Natural Detergent Alcohols (NDA)

Natural detergent alcohols or fatty alcohols are sourced from natural oils, mainly lauric. They can be produced either by direct hydrogena-tion of the corresponding fatty acid, hydrogenation of the corresponding methyl esters (FAME), or hydrogenation of wax esters - the most recent process variant. The catalysts are applied in slurry processes as oxidic powders or in fixed-bed processes. They are generally prereduced and stabilised.

G-99 Series The G-99-series are copper chromite catalysts, manganese- promoted, with increasing barium contents. The catalysts are highly poison resistant, especially against chlorine and sulphur, and feature excellent separation properties.

They are supplied in the form of oxidic powders for slurry applications. The type of catalyst to be used must be selected with care, depending on the sulphur and chlorine level of the different feeds and on the separation system. For a detailed recommendation, please contact our technical service. For fixed-bed applications, G-99B-0 is used in tablet form.

Caprolactam from Benzene

This process involves the following steps: Benzene is firstly hydrogen-ated to cyclohexane. Cyclohexane is then oxidised to a mixture of cyclohexanol and cyclohexanone. The cyclohexanol is dehydrogen-ated to cyclohexanone. After the oxime is formed, caprolactam is obtained by performing a Beckman rearrangement. For the hydrogenation of benzene to cyclohexane, nickel catalysts are applied in either continuous slurry processes or isothermal fixed-bed processes, the latter being more common. NiSAT® 320 RS powder is used for the slurry process, while for the fixed-bed process we recommend using our NiSAT® 200 catalyst in RS form.

After the trimerisation of butadiene to cyclododecatriene (CDT), epoxidation followed by two-step hydrogenation produces cyclo-dodecanol. Nickel-based catalysts are used for the trimerisation stage. Nickel and palladium catalysts are recommended for the subsequent hydrogenation steps. For the dehydrogenation of cyclododecanol to the corresponding cyclic ketone, meanwhile, a copper/zinc-based catalyst like PolyMax 301 is used.

Selection of the catalyst depends very much on the type of resin and the molecular weight of the polymer. For abietinic resins, for example, palladium catalysts are ideal, where as for specific C5 petroleum resins, nickel powders may be more effective. In some cases it is advisable to use catalysts with a caustic promoter or promoted with zirconium. Those types are available on request.

Treatment of Fischer-Tropsch Waxes

A special case in the hydro-treatment of high molecular compounds is the treatment of Fischer-Tropsch waxes. FT waxes typically contain carbonylic unsaturates which are sometimes conjugated giving the wax a faint yellow coulour. This colour has to be removed for a variety of applications. Furthermore, FT waxes can contain traces of iron which are typically removed prior to a hydro-genation treatment with ActiSorb® 400.

Oil Refinery Industry

Fuel Technology

For the production of transportation fuels, Süd-Chemie supplies special catalysts with superior catalytic properties. These are largely sophisticated, high-value zeolite products. Over just a short period of time, we have diversified our activities in this area and developed new catalyst formulations with outstanding cata-lytic performance compared to products available on the market. This exceptional standard of quality and performance is the fruit of our inten-sive cooperation with engineering partners and refineries. As a conse-quence, Süd-Chemie, together with its partners, is in a position not only to supply the catalyst, but to offer a full package consisting of both the catalyst plus process technology for petrol and diesel production.

Size [mm] 6 x 6 1.5 1.5

Dearomatisation (Sulphur-bearing Feedstock) – ASAT®

Efficient low-temperature dearomatisation of middle distillates is usually accomplished with noble metal catalysts rather than nickel catalysts. The latter suffer from an affinity to sulphur, leading to their subsequent deactivation. New catalyst systems with dual noble metal function have recently emerged on the market. These are supposed to be tolerant to much higher levels of sulphur than standard platinum catalysts. The most recent development in this family of HDAr catalysts is the ASAT® catalyst series. ASAT® is a noble-metal-promoted zeolite catalyst, which offers HDS, HDN and HDAr service as a trifunctional catalyst. Its most outstanding feature is its extreme tolerance of sulphur (up to 500 ppm wt.).

89


These catalysts feature outstanding capabilities for upgrading middle distillate cuts, converting sulphur down to ppm level, PNA and total ni-trogen to non-detectable level, and reducing total aromatics from 40% to less than 5%. ASAT® catalysts can thus easily convert light cycle oil (LCO) to “sulphur-free” diesel fuel in a one-stage unit.

Wax and Lube Oil

The first step in the manufacture of lubricants involves separating the individual fractions according to viscosity and boiling range specifications. The raw lube oil fractions from most crude oils contain components which have undesirable characteristics for the finished lubricant. These must be removed or converted by means of proc-esses such as extraction, hydrodewaxing or hydrotreating. Undesirable characteristics include high pour points, high cloud points, large viscos-ity changes with temperature (low VI), poor oxygen stability, poor colour, high organic acidity and high carbon and sludge-forming tendencies. Süd-Chemie’s lube oil processing catalysts help the refiner to meet specifications with regard to these crucial lube oil properties.

Hydrogen Production The production of hydrogen involves the use of several key unit opera-tions for which Süd-Chemie supplies catalysts. These are:

• Feedstock purification

• Prereforming

• Fired reformer

• CO conversion

• Methanation

• Sour gas shift

• Methanol reforming

Typically, two or more of these processing units are involved in virtually all plant configurations.

Prereforming

A prereformer is an adiabatic fixed-bed reactor upstream of the primary reformer. It allows increased flexibility in the choice of feed-stock, increased life time of the steam-reforming catalyst and tubes and the option of increasing the overall plant capacity. Furthermore, it operates at lower steam/carbon ratios.

Reforming for Direct Reduction of Iron Ore

Süd-Chemie supplies the complete portfolio of catalysts specifically formulated for direct reduction of iron (DRI) reforming furnaces. Our cooperation with MIDREX has produced catalysts comprising NiO as the active component on rugged carriers such as MgO, α-Al2O3 or calcium-aluminate.

Production of Town Gas

The conversion of naphtha into town gas requires a special type of nickel catalyst, ReforMax® 450 LDP, which is able to withstand the severe conditions in these cyclic reformers.

Downstream of the cyclic reformers, there is the option of installing a CO conversion using the standard HTS catalyst ShiftMax® 120.

116

Custom Catalysts

À la carte Catalysts

As a customised catalyst group, Süd-Chemie has a long history of manufacturing quality catalysts à la carte. Indeed, customised catalyst manufacture accounts for a significant proportion of our business.

Since the 1960s, customers have come to us both to manufacture new catalysts for commercialisation and to improve the catalysts they already use. Whether a petrochemical, refining, chemical, or engi-neering company approaches us for manufacturing or developing a catalyst from concept to completion, we have the resources, systems, and people to provide the level of service and confidentiality that any custom project may entail.

117

Custom Catalysts

Three types of customer relationships are generally identified:

Toll Manufacture Catalysts are produced exclusively for the customer in line with the customer’s expertise.

Licensed Manufacture Catalysts are produced relying on the customer’s expertise, but marketed and sold by Süd-Chemie (either freely or with specific restrictions). The customer receives royalty payments on sales.

Custom Manufacture Catalysts are developed on the basis of Süd-Chemie’s expertise, but produced exclusively for the customer in question.

Although Süd-Chemie does not sell process design services per se, customers can benefit from the expertise and services of Süd-Chemie’s entire technical staff whether in the context of investi-gating and establishing operating conditions, or for recommendations on a specific catalyst in answer to any requirement or problem.

Fuel Cell TechnologiesEnergy in tight spaces

There are works of art that burst with energy. Whoever wants to see them like this in colour, form and imagery,

needs high tech without compromises. That is why Süd-Chemie develops catalysts for hydrogen extraction

for laptops, cameras and mobile phones.

120

Fuel Cell Technologies

Süd-Chemie also applies its core competence in the field of hydrogen technology to the business area of Fuel Cell Technologies. Hydrogen is the feed for all fuel cell types, including PEMFC, MCFC and SOFC. In tandem with our partners, we work at a global level to develop all possible applications for fuel cells, whether mobile or stationary.

121

Fuel Cell Technologies

Süd-Chemie’s fuel-processing catalysts can handle virtually all hydrocarbon feedstocks, such as:

• Natural gas

• LPG

• Petrol

• Kerosine

• Diesel

• Heating oil

The conversion of these feeds to hydrogen involves the use of several key steps, for which Süd-Chemie supplies the catalysts.These are:

• Desulphurisation

• Reforming

• Prereforming

• Steam reforming

• Autothermal reforming

• Catalytic partial oxidation

• CO shift

• Selective CO oxidation

• Selective CO methanation

• Combustion of fuel cell off-gases
