Abstract: A method for oxidizing carbon monoxide (CO) and volatile organic compounds (VOCS) comprises contacting a gas containing water vapor and said CO and VOCs with a catalyst composition comprising at least one base metal promoter and at least one base metal catalyst supported on an oxide support material comprising one or more of alumina, silica, zirconia, ceria, and titania, wherein the VOCs comprise one or more of methyl acetate, methane, methyl bromide, benzene, methanol, methyl ethyl ketone, butane, and butene.

Abstract: A catalytic material for treating an exhaust gas produced by a natural gas engine, which catalytic material comprises a molecular sieve and a platinum group metal (PGM) supported on the molecular sieve, wherein the molecular sieve has a framework comprising silicon, oxygen and optionally germanium, and has a content of heteroatom T-atoms is ?about 0.20 mol %.

Abstract: 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.
