US Patent 7807110 Catalyst systems

The present invention provides monolithic structural catalysts. The catalysts have a thin wall structure and are advantageous for catalyzing reactions of gaseous fluid or liquid fluid molecules, such as the denitration or selective catalytic reduction (SCR) of nitrogen oxides (NOx) in combustion flue gases. In an embodiment, the honeycomb-like monolithic structural body includes catalytically active outer peripheral walls and a plurality of catalytically active thin-walled inner partition walls, the thin-walled inner partition walls adapted to enhance fluid flow through the monolithic catalytic body and to increase interaction of the fluid molecules with the catalyst body.
