Future global prosperity will depend on new or improved processesthat are economically and environmentally sustainable. This is the

paradigm shift of the early 21st century, driven by the threat of climatechange and the increasing scarcity of raw materials. Catalysis has aleading role in many chemistry solutions, as the key enabling sciencein some cases, and as part of general technology in others. Catalysis is

used widely within chemical production (petro- and oleo- chemical),power production, refinery processes, conversion of natural gasses,agro chemistry, pharmaceutical processes, polymer and material

production and biotechnology. The economic impact of catalysis isperhaps best illustrated by the fact that 20-25% of the gross nationalproducts in the industrialized world involved heterogeneous catalysis.Many of the major problem society is encountering, such as the needto create production in balance with the environment, better use offuels, more economical energy production and the reduction of greenhouse gasses (mainly CH4 and CO2), which will require solutionswhere catalysts play an significant role. The development of newcatalysts and catalytic processes can open up new selective chemical

processes which may lead green processes with a considerablereduction of undesired by-products or waste products. The lecture willdiscuss on the challenges in the development of catalytic conversionfor efficient utilization of biomass for sustainable supply of bioenergyand chemicals.

SOLID BASE CATALYSIS; BASIC SITE GENERATION AND

CATALYSIS IN ORGANIC REACTIONS

Hideshi Hattori

Catalysis Research Center, Hokkaido University

Environmental impacts should be taken into account for development ofindustrial chemical processes both at present and in future. One of theeffective improvements will be achieved by replacement of homogeneouscatalytic systems by heterogeneous catalytic systems. This is particularly truewith the processes involving acid- and base catalyzed reactions. Applicationsof homogeneous acid and base catalyst systems cause unavoidable problemswith corrosion of reactors, separation and recycling of the catalysts, highcosts for waste disposal and waste water treatment. At the end of reactions,the catalysts should be neutralized to form metal salts in most cases, which

produces a large amount of by-products.

In contrast to the extensive studies and applications of solid acid catalysts,fewer efforts have been devoted to solid base catalysts. Based on thefundamental studies of solid base catalysts, which started in 70s, industrialapplications of solid base catalysts have been appearing for the last twodecades. Applications of solid base catalysts are all in petrochemical

processes, no petroleum refining processes utilize solid base catalysts.Nevertheless, there is a great demand for solid base catalysts to be utilized inchemical processes, in particular in the areas of the organic synthesis of fineand intermediate chemicals.

In the present lecture, I will discuss the generation of basic sites, types ofsolid base catalysts, catalysis of solid base catalysts in fundamental reactions,and applications of solid base catalysts in industrial processes.

BEAD-MILLING AND POST-MILLING

RECRYSTALLIZATION: AN ORGANIC TEMPLATE-FREE

METHODOLOGY FOR THE PRODUCTION OF NANO-ZEOLITE CATALYST

A new method for the production of nanosized zeolite powder by a top-downapproach has been performed. [1,2] In this study, ZSM-5 (MFI type structure)was first milled to produce a nanopowder. This technique can destroy theouter portion of the zeolite framework, which lowers the micropore volumeof ZSM-5 zeolite. To remedy this, the damaged part was recrystallized usinga dilute aluminosilicate solution after bead milling. From the combined beadmilling and post-milling recrystallization, nanosized ZSM-5 zeoliteapproximately 50 nm in size with high crystallinity was obtainedsuccessfully.

Commercial ZSM-5 was milled using a bead milling apparatus (Minicer,Ashizawa Finetech, Ltd., Tokyo, Japan) for 2-6hours. Recrystallization of themilled ZSM-5 was performed using dilute silicate solution with thecomposition of 0.0525 Na2O : 0.117 SiO2 : 10.0 H2O. The importance of this

particular ratio is that it provides a solution nearly in equilibrium with ZSM-5. This means that ZSM-5 neither undergoes macroscopic growth nordissolution. Under these conditions, the remaining ZSM-5 crystallites act asseeds and the poorly crystalline parts of the milled ZSM-5 are more easily

recrystallized back onto the ZSM-5, resulting in a more ordered product.Obtained samples were evaluated as acid-catalysts for cumene cracking. Thetest reactions were conducted so that diffusion through the zeolite porestructure was the rate-determining step of the catalytic reaction. As a result,ZSM-5 zeolite powder showed a higher catalytic activity in cumene crackingin comparison with the raw ZSM-5 zeolite. Furthermore, the decrease incrystal size suppresses catalyst deactivation through coke deposition duringcumene cracking.

REFORMING OF LIGHT NAPHTHA WITH Pt/L ZEOLITE

CATALYSTS

One of the most recent breakthrough in industrial catalysis forpetrochemicals is the direct conversion of hexanes to benzene using Platinumdeposited on alkaline L zeolite. This latter owns non interconnected channelswith a pore limiting diameter of 0.81 nm and with a largest cavity diameter of0.107 nm. The discovery was done within the labs of the French ElfAquitaine Company which merged later with Total Oil Company. The

purpose of the research was initially to dehydrogenate selectively n-paraffins.During this period, an already known phenomenon was rediscovered, thedehydrocyclization properties of Pt/alkaline X and Y zeolites. The researchwas extended to other medium/large pores zeolites. Thus was discovered theunique properties of Platinum on Potassium exchanged L zeolite for hexane

aromatization to benzene. Elf Aquitaine did not want to develop the processso the discovery was published in 1980 [1].

At that time, it was recognized that the catalysis was done only by the metal,since any introduction of acidity was detrimental to selectivity and stability.The first fundamental studies [2] suggested that Pt could be modified by anelectronic interaction with the alkaline carrier. It was also obvious that theactivity was limited by internal diffusion within the zeolite crystal. This wasalso detrimental to selectivity and to cycle length. Indeed this cycle lengthwas too short to envisage a commercial application. Then the patents weresold to several other companies which were able to develop the process withvarying degrees of success.

A lot of applied and fundamental research was done to develop a commercialcatalyst and to explain the unusual activity and selectivity of the Pt/KLcatalyst. An alternative catalyst using Barium exchanged L zeolite as thecarrier was found to exhibit comparable performances. This carrier is

recognized to be no more acid than the KL one.

Three non exclusive hypothesis are now proposed to explain the role of thezeolite: Zeolite channels are stabilizing small metal particles (< 0.7 nm) under

reaction conditions. The high selectivity could be due to an electronictransfer from zeolite to Pt [2,3].

The channel structure of the L zeolite may impose a terminaladsorption mechanism of n-hexane on Pt. This would favordehydrocyclization to benzene [4,5].

It is demonstrated that the channels of the L zeolite inhibit stericallybimolecular reactions leading to intracrystalline coke [6]. Andselectivity would be better on clean Pt surface.

Despite this stabilization effect, the first catalysts suffered from rapiddeactivation for two reasons:

1. The molecular traffic of reactants and products within the 0.7 nmdiameter mono-dimensional pore system containing Pt clusters mayintroduce limitation by diffusion. Thus the zeolite synthesis must beoptimized to produce short channeled zeolite crystals. Any coke

formation within the crystal deactivates quickly the catalyst by poreplugging. Any Pt excess would have a similar effect as brightlydiscussed by Treacy [7].

2. The catalysts are extremely sensible to sulfur poisoning whichprovokes Pt sintering, leading to channel blockage [8]. Thus the sulfurcontent of feed must be smaller than 50 ppb.

Because of this very severe specification, the furnaces upstream the industrialreactors must be prevented from metal dusting. This is a key point for the

success of the commercial operation.

SYNTHETIC STRATEGIES FOR ALIPHATIC POLYESTERS

USING COBALT COMPLEXES

Yessi Permana

[email protected]

Aliphatic polyesters such as poly(hydroxyalkanoate)s (PHA) have adegradable character and are generally derived from microorganisms.Synthetic strategies towards such polyesters are of highly importance tocontribute the demand of PHA-based materials in medical deviceapplications. The strategy involves the copolymerization of carbon monoxide(CO) with cyclic ethers or with olefin alcohols. Polymerization ofoxetanes/CO catalyzed by cobalt phosphine complexes (AcCo(CO)3[P(p-tolyl)3]and AcCo(CO)3[P(OPh)3]) has been reported to give poly(-lactone)(which is known to be difficult to produce from a ring opening

polymerization of thermodynamically stable -lactone) with 63% of COincorporation in the polymer unit.1

Longer aliphatic polyester was reported to produce by a copolymerization of

undec-10-en-1-ol and carbon monoxide at high CO pressure of 190 bar usingCo2(CO)8/pyridine catalyst adduct.

2 In this work we describe an alternativeroute in the copolymerization of undecenol/CO with lower CO pressure (upto 40 bar) using a hydride cobalt complex prepared in situ fromCo2(CO)8/H2.

3 We observed a formation of solid polymers which was hardlysoluble in most organic solvents.

An attempt to explain the mechanistic route was carried out by a DFT/B3LYPcomputational method using a cc-pvDZ basis set for all atoms. Calculationresults showed that activation energy of an associative pathway was lowerthan a dissociative pathway. However, the calculation of theoretical reactionrate for dissociative pathway was much higher than the associative one. Theactivation energy of 2,1-insertion step was observed to be higher than the

olefin 1,2-insertion step which was also in good agreement with previousexperimental results.

Plasma-chemical methods for hydrogen production from natural gas such asmethane through methane decomposition, partial oxidation and/or steamreforming processes are considered among the most promising. The effect of

plasma may consist both in gas heating and in generation of chemicallyactive species (excited molecules, radicals, ions, electrons) in collisions ofgas molecules with electrons. Therefore, the plasma processing ofhydrocarbon gases due to production of active species could be energeticallyeffective only in the case if these active species are capable of participating inchain reactions, that is, to serve as catalysts. When a gas phase consistingelectrically neutral species, electrons, ions and other excited species flowthrough the catalyst bed, the catalyst particles become electrically charged.The charge on the catalyst surface, together with other effects of excitedspecies in the gas discharge leads to the variations of electrostatic potential ofthe catalyst surface. The chemisorption and desorption performances of thecatalyst therefore may be modified in the catalyst surface. Effects of thesemodifications on methane conversion are dependent on the amount andconcentration of surface charge and the species present at the catalyst surface.The combining plasma discharge and a heterogeneous catalyst are possible toactivate the reactants in the discharge prior to the catalytic reaction, whichshould have positive influences on the reaction conditions. Since most of theenergetic electrons are required to activate the CH4 and CO2 gases in adischarge gap, special consideration must be taken in the designing a reactorthat maximizes the contact time between the energetic electrons and theneutral feed gas species. The catalyst located in the discharge gap is analternative way to increase the time and area of contact between gasmolecules and energetic electrons in addition to other modification ofelectronic properties.

Heterogeneously chemoselective hydrogenation of furfural over nanoporousNi-Sn alloy catalysts is rarely investigated. The alloying of nickel withsecond electropositive metal such as tin (Sn) could improve its affinitytowards C=O rather than C=C in ,-unsaturated carbonyl compounds [1].We have developed Ni-Sn alloy both bulk and supported via a very simplesynthetic procedure and gave high yield of unsaturated alcohols [2]. Herein,we have extended our study to the effect of hydrogen treatment of as-

prepared Ni-Sn at 673-873 K and applied chemoselective hydrogenationfurfural (FFald) to furfuryl alcohol (FFalc).

Despite several studies, the use of CO2 as a chemical reactant is currentlylimited to a few processes. With the aim to formulate an efficient catalyst forCO2 conversion into methane, nickel was selected, being well known to be

active for the catalytic CO2 methanation. Mesostructured silica nanoparticles(MSN) was chosen as a support because of its high surface area. MSN and Niloaded onto MSN (Ni/MSN) were prepared by the sol gel and impregnationmethods. Catalytic testing was conducted in the temperature range of 423-723 K under atmospheric pressure in the presence of H2. The Ni/MSN wascompared with others types of support such as MCM-41 and SiO2. Theactivity of CO2 methanation followed the order: Ni/MSN > Ni/MCM-41 >

Ni/SiO2. The high activity of Ni/MSN is due to the presence of both intra-and interparticle porosity which led to the high concentration of basic sites

evidenced by N2 isotherm and pyrrole adsorbed IR spectroscopy results. Themethanation activities were found to be correlated to the concentration of

basic sites. The presence of defect sites or oxygen vacancies in MSN wasresponsible for the formation of surface carbon species, while Ni sitesdissociated hydrogen to form atomic hydrogen. The surface carbon speciesthen interacted with atomic hydrogen to form methane. The Ni/MSN catalyst

performed with good stability and no deactivation up to 200 h.

The catalytic activity of MoO3ZrO2 and Pt/MoO3ZrO2 has been evaluatedbased on the C5C7 linear alkane hydroisomerization in a microcatalyticpulse reactor at 323623 K. The introduction of Pt on MoO3ZrO2 did notchange much the crystallinity and BET specific surface area of MoO3ZrO2

but altered significantly the concentration of acid sites of MoO3ZrO2. Thecatalytic activity of Pt/MoO3ZrO2 was inferior to that of MoO3ZrO2,although the Pt/MoO3ZrO2 performed higher hydrogen uptake capacity.ESR and IR spectroscopy revealed that the presence of Pt enhanced thehydrogen adsorption rate and capacity of MoO3ZrO2; however, theinteracted-hydrogen did not successively form active protonic acid sites butintensified the Lewis acid sites. Contrarily; heating of Pt/MoO3ZrO2 in the

presence of hydrogen at higher temperature did not form protonic acid sitesbut intensified Lewis acidic sites. It is suggested that Pt facilitates in theinteraction of spiltover hydrogen atom and MoO3 to form MoO2 or Mo2O5over ZrO2 support which may be intensified the Lewis acidic sites.

Utilization of catalyst from waste shell clamshells (Meretrix meretrix) viamodification of hydration technique not only economical and environmentalfriendly , it is also efficient and easy to manufacture. This heterogenouscatalyst come from hydration shows high basicity as well as high surfacearea that exhibits higher catalytic activity than CaO itself. The CaO fromcalcinations of clam shell at 900 oC were refluxed inside the water for1,3,6,9,and 12 hours and reheated it again at 600 oC to produce mixedcalcium oxide and calcium hydroxide. Elongating the time during refluxing

the CaO in water shows result in high basicity of catalyst and surface areathat leads to the high catalytic activity.This mixed calcium oxide and calciumhydroxide for 1,3,6,9,and 12 hours water treatment were used as a catalyst intransesterification reaction between palm oil and methanol to produce

biodiesel. It revealed that 1,3,6,9 and 12 hours water treatment catalyst resulttransesterification reaction shows completed reaction (FAME yield >88%,94%,96.5%, 98%, 98.7%) in 2 hours; methanol/oil molar ratio of 9:1;reaction temperature of 60-65 oC; 1wt% catalyst loading. The result obtainedfrom this study revealed prolonged the treatment process will generates newcatalyst that have high surface area and more even distribution. Watertreatment have strong effect on crystallic size of the catalyst whichcontributing to the smaller particle size that have high surface area. Thistechnique also cause the desorption peak shift to the upward shift suggestinghigh basicity of the catalyst.

The effectof barium (Ba) incorporation into microporous CHZSM5 synthesized viawetness impregnation method, on the product distribution and chemicalcomposition of bio-oil were also investigated. The catalysts synthesized werecharacterized using X-ray diffraction (XRD), nitrogen adsorption-desorptionisotherms (BET), scanning electron microscopy (SEM), fourier transforminfrared (FT-IR) spectroscopy, H2 temperature programmed reduction (H2-TPR) and NH3 temperature programmed desorption (NH3-TPD) techniques.The crystalline structure of CHZSM5 remained intact after theimplementation of Ba as proved in XRD. It shows that the Ba well-dispersedinto the wall of the CHZSM5. With the increasing of Ba content (~3-30%),the ordering of the hydrogen consumption and acidity significantly increased,respectively. However, it gave vice versa effect in the surface area of thesynthesized catalysts (~400-200 m2g-1). The composition of the bio-oil

produced from pyrolysis reaction were analyzed using fourier transforminfrared (FT-IR) spectroscopy and gas chromatography mass spectrometer(GC-MS) to evaluate the effect of catalytic upgrading. With the properdistribution of Lewis and Brnsted (weak and strong) acid sites, Ba-CHZSM5 showed good activity and selectivity for the production ofdesirable organic compounds in comparison to commercial CHZSM5.

The potential of binary metal oxide catalysts, NiO/CaO for thetransesterification of palm oil for biodiesel production was investigated.Three different methods were used to deposit 5wt% NiO onto CaO catalysts(i.e., impregnation, co-precipitation and sol-gel). The physicochemicalcharacteristic of the prepared catalysts were characterized by means of X-raydiffraction (XRD), temperature programmed desorption of CO2 (TPD-CO2),X-ray fluorescent (XRF) and field emission spectroscopic electronmicroscopy (FESEM). These synthesized catalysts were used for thetransesterification of palm oil as feedstock with methanol to produce

biodiesel fuel at various reaction conditions. The activity of 5wt% NiO/CaO

catalyst prepared by sol-gel method showed superior activity compared toother methods. The catalyst exhibited the highest conversion of palm oil to

biodiesel with 97.34% compared to 85.03% and 90.41% for co-precipitationand impregnation, respectively. The optimum condition were observed attemperature 338 K, 10:1 molar ratio of methanol to oil, 1 wt% catalystamount and 2 hours reaction time. Different preparation methods have shownsignificant effects in physicochemical characteristic of the prepared catalystand hence influence the catalytic activity of the catalysts.

In this study, the nitrationreaction was performed homogeneously using concentrate HNO3 and H2SO4and was compared with the use of concentrate HNO3 and solid acid catalystSiO2-H2SO4.

Prestudy was conducted on the nitration reaction of benzaldehyde, in whichthe homogeneous catalysis reaction was succeeded in 10 minutes at room

temperature, whereas over SiO2-H2SO4 the nitration products, which are2-nitro-benzaldehyde, 2,4-dinitro-benzaldehyde and 2,4,6-trinitro-benzaldehyde, were formed after 5 h reaction time. The nitration of eugenol,isolated from clove oil, were also performed homogeneously andheterogeneously, in which the reactions products were characterized usingTLC-Scanner, LC-MS and GC. The MS analysis showed that two nitrogroups were bound to the aromatic ring of eugenol over heterogeneouscatalysis, whereas over the homogeneous catalysis three nitro groups were

bound to the aromatic ring. Based on GC analysis, the conversions ofeugenol were almost 100% and the %-yields were 78.39%, 87.37% and99.96% respectively for 6h, 12h and 18h reaction periods .

The use of cationic polymers, 2-(Acryloyloxy)-N,N,N-trimethylethanaminium chloride in co-MET technique serves to stabilize theemulsion and form mesoporous structure. In this study, FeCl3 and HSO3CF3were impregnated into macro/mesoporous silica and then werecharacterizated using SEM, EDS, FTIR, and XRD. SEM data show that thesilica pores generated in increases with increasing concentrations of cationic

Nowadays, zeolites with a micro-/meso-porous hierarchical structure haveattracted much attention due to their improved diffusion, catalytic activity,selectivity and lifetime. Generally, several strategies for introduction of

mesoporosity can be distinguished, including soft template and hardtemplates. However, new synthesis method in absence of organic templatehas been searched becuse it causes many problems of adverse such as high

production cost, contamination by waste water, air pollution arising fromthermal decomposition of organic species contained in channel system, andcoke deposit due to incomplete decomposition [1, 2]. In this research, wereport an effective and an economic synthesis procedure for resultinghierarchically porous MFI zeolite without organic template (structure-directing agent SDA and surfactant molecule). A dense dried precursor gel

consisting of silica source, alumina source, mineralizer, water and seed (2%w/w) were transformed into zeolites under hydrothermal steam-assistedconditions at 150 C [3]. We find out that the dense precursor gel can easily

be converted in one day into mesoporousMFI zeolite in absence organictemplate.we observe a large hysteresis in these MFI zeolite between theadsorption and desorption branch, it shows a dominant pore diameter of 5 nmof this secondary pore system when analyzed with the NLDFT method.

High silica zeolites hasbeen synthesized using organic molecule that can bedecomposed within the zeolite pore. Organic compounds that have cyclicketal group are potential to be green Structure-Directing Agent (SDA)

because it stable during the zeolite synthesized condition but can bedecomposed in acidic condition. In this research, we report zeolites synthesisusing two different cyclic ketal compounds as SDA. The SDA is mixed in thealuminosilicate gel under molar composition of SDA/Si = 0,033 andhydrothermally treated at 175C for 6 days. XRD pattern shows that the solid

product which synthesized using sol ketal have similar pattern with the solid

product which synthesized in the absence of SDA. Meanwhile, in thepresence of ammonium dioxolane salt as SDA the crystallization leads to theformation MFI zeolite. The ammonium dioxolane compound was fragmentedinside the zeolite pore by treating in acidic solution using 1M HCl at 80Cand the cation fragment was removed by ion exchange method.XRD patternsshow that SDA zeolite framework was not destroyed during the SDAremoving process.

Hierarchical zeolites showing interstitial mesopore space in-between thecrystalline phase have been offered as the solution to the intracrystallinediffusion limitations of catalyzed reactions. The objective of creatingmesoporosity on zeolite crystal surface is to enhance accessibility, rate ofoverall catalyzed processes, (molecular diffusion), separation (shapeselectivity) and to inhibit the catalyst deactivation process. Hierarchically

porous zeolites are normally synthesized via direct bottom-up technique byhydrothermally treating the zeolite precursors and mesoporogen. Themesopore generating species from self-assembly of surfactant molecules isincorporated to generate the mesoporosity during the crystallization ofzeolite. This mesopore templating pathway is mostly tested for obtainingmesoporous high silica zeolite such as ZSM-5 in which the nucleation andcrystallization of the zeolite is induced by additional organic compound asthe structure-directing agent (SDA). We would like to observe themorphological change in this mesoporous ZSM-5 by varying theconcentration of mesoporous-generating agent and some synthesis techniquemodification.

Keywords: MFI, mesoporous, hierarchical, surfactant, SDA-free.

MFI-Type zeolite can be synthesized using hexamethylenetetramine asstructure directing agent (SDA). The reaction was carried on 150 oC for 6days. The solids obtained were characterized by X-ray Diffraction. 29Si and27Al magic angle spinning magnetic resonance, scanning electron microscopy(SEM) and nitrogen adsorption. The SEM images revealed that thesynthesized MFI-type zeolite has an unusual ball-like morphology whichdiffer from usual coffin shaped MFI-type zeolite. The study on the amount ofSDA used in synthesis has been done. The reduction amount of SDA shows agood result in resulting MFI-type zeolite, but the addition amount of SDA didnot result in MFI zeolite.
