| 20100209327 | STRUCTURED SCR CATALYST FOR THE REDUCTION OF NITROGEN OXIDES IN THE EXHAUST GAS FROM LEAN-BURN ENGINES USING AMMONIA AS REDUCING AGENT - The reductive removal of nitrogen oxides from the exhaust gas from internal combustion engines operated predominantly under lean conditions takes place in a selective catalytic reduction (SCR) of the nitrogen oxides by means of ammonia or a compound which can be decomposed into ammonia as reducing agent. Conventional SCR catalysts typically have a relatively narrow working temperature window, usually 350° C. to 520° C., in which good nitrogen oxide conversions can be achieved with sufficient selectivity. SCR catalyst formulations whose working window is in the temperature range from 150° C. to 350° C. generally not be used at higher temperatures since they oxidize the ammonia required as reducing 18 agent to nitrogen oxides at above 350° C. To cover the entire exhaust gas temperature range typical of vehicles having been operating internal combustion engines extending from 200° C. to 600° C., it has therefore mostly been necessary to use complicated exhaust gas systems containing a plurality of catalysts having different working temperature ranges. Disclosed is a structured SCR catalyst whose working range extends over a significantly broader temperature window and by means of which complicated exhaust gas units can be considerably simplified, with a saving of components. | 08-19-2010 |
| 20110056187 | METHOD FOR DECREASING NITROGEN OXIDES IN HYDROCARBON-CONTAINING EXHAUST GASES USING AN SCR CATALYST BASED ON A MOLECULAR SIEVE - The invention relates to a process for treating diesel engine exhaust gases comprising nitrogen oxides (NO | 03-10-2011 |
| 20110142737 | SELECTIVE CATALYTIC REDUCTION OF NITROGEN OXIDES IN THE EXHAUST GAS OF DIESEL ENGINES - A catalyst and a process for selective catalytic reduction of nitrogen oxides in diesel engine exhaust gases with ammonia or a compound decomposable to ammonia are described. The exhaust gas to be cleaned is passed together with ammonia or a compound decomposable to ammonia over a catalyst which comprises a zeolite or a zeolite-like compound containing 1-10% by weight of copper, based on the total weight of the zeolite or of the zeolite-like compound, and a homogeneous cerium-zirconium mixed oxide and/or a cerium oxide. The zeolite used or the zeolite-like compound used is selected from the group consisting of chabazite, SAPO-34, ALPO-34 and zeolite-β. | 06-16-2011 |
| 20110146237 | EXHAUST GAS PURIFICATION SYSTEM FOR THE TREATMENT OF ENGINE EXHAUST GASES BY MEANS OF SCR CATALYST - An exhaust gas purification system (method and device) for the treatment of diesel exhaust gases containing nitrogen oxides and hydrocarbons is disclosed, which comprises the addition of ammonia or of a compound decomposable to ammonia into the exhaust gas stream and the subsequent leading of the exhaust gas stream over two successively arranged SCR catalysts with different properties and compositions. Both SCR catalysts are free of vanadium compounds and only the downstream SCR catalyst contains zeolite compounds. The exhaust gas purification system according to the invention is characterized by good “kick-off” behavior at low temperatures and a simultaneously high conversion performance over a wide temperature range. | 06-23-2011 |
