Fabrication Monolithic extrusion and drying of
the catalytic material
Catalytic material pressed and dried
on a metallic mesh
Length Up to 1300 mm 625 mm
Advantages bullHigher specific surface
bullWide range of pitches available
bullMore catalytic material
bullSpecially created for high dust
bullLess sensitive towards dust
Disadvantages
bullSmall pitches thin walls
mechanically less stable
bullHigh dust application requires
sophisticated cleaning
bullLess specific surface
bullLess catalytic material

One system for NOx VOC and CO reduction
NOx reduction 90 or le 100 mgNmsup3 (lt 10 mgNmsup3 ammonia slip)
CO VOC reduction 98 - 99
Catalyst deactivation nearly Low Dust SCR
Autothermic mode ndash no need of natural gas (only for start and stop mode) at 4000
mgNmsup3 CO concentration
Pressure drop 30 - 35 mbar (including flaps and ducts)
Use of secondary fuels or secondary raw materials is possible
