摘要: Catalyst articles having a first zone containing a first SCR catalyst and a second zone containing an ammonia slip catalyst (ASC), where the ammonia slip catalyst contains a second SCR catalyst and an oxidation catalyst, and the ASC has DOC functionality, where the first zone is located on the inlet side of the substrate and the second zone is located in the outlet side of the substrate are disclosed. The catalytic articles are useful for selective catalytic reduction (SCR) of NOx in exhaust gases, in reducing the amount of ammonia slip and in oxidizing organic residues. Exhaust systems containing the catalyst articles and methods of using the catalytic articles in an SCR process, where the amount of ammonia slip is reduced and hydrocarbon are oxidized by the ASC catalyst, are also described.

摘要: A highly practical SCR catalyst excellent in NOx purification performance is provided. The SCR catalyst includes a blend of an aluminosilicate molecular sieve that has supported thereon copper as an extra-framework metal and that has a CHA framework, and a silicoaluminophosphate molecular sieve that has a CHA framework, and is adapted to perform selective catalytic reduction of NOx. In the SCR catalyst, the silicoaluminophosphate molecular sieve and the aluminosilicate molecular sieve contain silicoaluminophosphate and aluminosilicate, respectively, in a molar ratio of silicoaluminophosphate:aluminosilicate of 0.1:1.0 to 0.4:1.0.

摘要: An engine system includes an electronically controlled compression ignition engine configured to burn diesel fuel and a high ash oil to produce an exhaust with a temperature and NOx to soot ratio as well as a controlled level of ash deposits on the particulate filter of the system. An aftertreatment system is fluidly connected to the engine and includes a diesel oxidation catalyst, a reductant supply, and a diesel particulate filter coated with a NOx reduction catalyst. The soot load density on the diesel particulate filter can be stabilized by oxidizing soot at about a same rate as the compression ignition engine is supplying soot to the aftertreatment system.
