20100192552 | EXHAUST GAS TREATMENT CATALYST, EXHAUST GAS TREATMENT METHOD, AND EXHAUST GAS TREATMENT APPARATUS - An exhaust gas treatment catalyst for removal of one or more pollutants in an exhaust gas, the catalyst comprising: a SO | 08-05-2010 |
20100284877 | 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 (NO | 11-11-2010 |
20110172090 | COMPOSITIONS AND METHODS FOR TREATING EXHAUST GASES - The present invention provides compositions, systems, and methods for achieving high efficiencies of nitrogen oxide (NOx) removal from exhaust gases while minimizing ammonia slip and sulfur dioxide oxidation. In one embodiment, a method of removing nitrogen oxides from an exhaust gas comprises providing a first catalyst layer, adding an ammonia-containing compound to the exhaust gas upstream of the first catalyst layer in excess of the stoichiometric equivalent of the nitrogen oxides in the exhaust gas, flowing the exhaust gas through the first catalyst layer, selectively catalytically decomposing ammonia in excess of the stoichiometric reaction equivalent of the nitrogen oxides in the exhaust gas, and catalytically reducing the nitrogen oxides by reaction with ammonia not selectively catalytically decomposed. | 07-14-2011 |
