Publication number: 20070082783Abstract: One or more parameters for denitration or desulfations of a LNT is varied, whereby the saturation of NOx and/or SOx in the LNT is reduced to a lower level when an operating state makes the LNT otherwise less effective or places a greater demand for conversion efficiency on the LNT. The operating state can relate to whether the LNT is at the limit of its effective operating temperature range, a degree of poisoning, or an engine operating state. Selectively tolerating high degrees of sulfur poisoning or NOx saturation during periods of low exhaust flow allows the efficiency of denitrations and/or desulfations to be increased over a large portion of a vehicle's operating cycle, particularly when the engine uses a CVT. Another concept relates to a power generation system comprising an engine tuned to efficiently operate in a narrow speed range for all levels of power output.Type: ApplicationFiled: April 21, 2006Publication date: April 12, 2007Applicant: Eaton CorporationInventors: Haoran Hu, Thomas Stover, James McCarthy

Publication number: 20070082809Abstract: Disclosed are a hydrothermally stable porous molecular sieve catalyst and a preparation method thereof. The catalyst consists of a product obtained by the evaporation of water from a raw material mixture comprising a molecular sieve having a framework of Si—OH—Al—, a water-insoluble metal salt and a phosphate compound. The catalyst maintains its physical and chemical stabilities even in an atmosphere of high temperature and humidity. Accordingly, the catalyst shows excellent catalytic activity even when it is used in a severe process environment of high temperature and humidity in heterogeneous catalytic reactions, such as various oxidation/reduction reactions, including catalytic cracking reactions, isomerization reactions, alkylation reactions and esterification reactions.Type: ApplicationFiled: June 28, 2006Publication date: April 12, 2007Applicants: SK CORPORATION, KOREA RESEARCH INSTITUTE OF CHEMICAL TECHNOLOGYInventors: Sun Choi, Yong Kim, Deuk Park, Suk Kim, Il Yang, Hee Kim, Yong Park, Chul Lee, Won Choi, Kwang Ko, Na Kang

Publication number: 20070082810Abstract: A coated metal substrate useful for carrying an exhaust emission treatment catalyst such as a three-way conversion catalyst for use with small engine platforms. The coated metal substrate comprises a metal such as a stainless steel, a carbon steel, a FeCr alloy, Hastelloy and the like. The coating on the metal substrate comprises an alumina silicate having alumina particles impregnated therein. The coating is applied using a liquid dispersion containing an aluminum silicate and the alumina particles are dispersed into the aluminum silicate coating while the coating is still wet. The coated metal substrate is then calcined. Thereafter, a washcoat containing an engine exhaust treatment catalyst may be applied to the surface of the coated metal substrate.Type: ApplicationFiled: November 22, 2006Publication date: April 12, 2007Inventors: Michael Galligan, Young Kim
