Publication number: 20140156207Abstract: A system and method of monitoring regeneration of a particulate matter filter for a stationary diesel engine is disclosed. The system monitors exhaust temperature and operating time of an engine to calculate accumulated operating time below a critical temperature. Upon reaching a maximum allowed accumulated operation time, the system initiates a warning signal to inform the operator to increase exhaust temperatures for passive regeneration of the filter. During regeneration, the system periodically measures filter pressure differential and the exhaust temperature to calculate a difference in pressure differentials measured at two different times and determine whether the difference is below a critical value to inform the operator that regeneration is complete.Type: ApplicationFiled: November 30, 2012Publication date: June 5, 2014Applicant: JOHNSON MATTHEY PUBLIC LIMITED COMPANYInventors: Rita Aiello, Richard Mark Paczewski, Kevin Carre, Paul Joseph Andersen

Publication number: 20130108530Abstract: A process for producing a ceria-zirconia-alumina composite oxide is disclosed. The process comprises combining a cerium (IV) compound and a zirconium (IV) compound with a slurry of aluminum oxide at a temperature greater than 40° C. to produce a reaction slurry, then contacting the reaction slurry with a precipitating agent to precipitate insoluble cerium and zirconium compounds onto the aluminum oxide and form cerium-zirconium-aluminum oxide particles, and calcining the cerium-zirconium-aluminum oxide particles to produce a ceria-zirconia-alumina composite oxide. The process to produce ceria-zirconia-alumina composite oxides provides a material having a high oxygen storage/release capacity that is suitable for a catalyst with enhanced cleaning of the exhaust gases from internal combustion engines.Type: ApplicationFiled: October 27, 2011Publication date: May 2, 2013Inventors: Hsiao-Lan Chang, Scott Daniel Cauffman, Haiying Chen, Paul Joseph Andersen
