Abstract: Organosilica materials, which are a polymer of at least one independent monomer of Formula [Z1OZ2OSiCH2]3 (I), wherein each Z1 and Z2 independently represent a hydrogen atom, a C1-C4 alkyl group or a bond to a silicon atom of another monomer and at least one other trivalent metal oxide monomer are provided herein. Methods of preparing and processes of using the organosilica materials, e.g., for catalysis etc., are also provided herein.

Abstract: Adsorbent materials comprising a core, for example CHA, and at least one coating, for example DDR, are provided herein. Adsorbent contactors and gas separation processes using the adsorbent materials are also provided herein.

Abstract: Catalyst compositions suitable for use in the exhaust gas recycle stream of an internal combustion engine are provided. Such catalyst compositions typically provide significant amounts of methane in addition to syngas. A reformer incorporating such a catalyst for use in an exhaust gas recycle portion of an internal combustion engine powertrain is described. A powertrain incorporating such a reformer, a method of increasing the octane rating of an exhaust gas recycle stream, and a method of operating an internal combustion engine using methane-assisted combustion are also described.

Abstract: Diesel exhaust treatment articles, systems and methods are disclosed. According to one or more embodiments, an oxygen storage component is utilized and degradation of the oxygen storage component is correlated with degradation of the hydrocarbon conversion efficiency of a catalyst in a diesel engine system.

Abstract: The present invention is directed to a diesel oxidation catalyst for the treatment of exhaust gas emissions, such as the oxidation of unburned hydrocarbons (HC), and carbon monoxide (CO) and the reduction of nitrogen oxides (NOx). More particularly, the present invention is directed to a novel washcoat composition comprising two distinct washcoat layers containing two distinctly different ratios of Pt:Pd.

Abstract: An NOx emission system for diesel powered vehicles has a “Y” exhaust system with an NOx adsorber catalyst in each leg and an oxidation catalyst in the combined leg. One bank of cylinders sends exhaust gases to one of the “Y” legs while a second bank of cylinders send exhaust gases to the other “Y” leg. Composition of the exhaust gases in each leg is independently controlled by the engine's ECU so that exhaust gases in one leg are rich for regenerating the NOx adsorber catalyst in that leg while exhaust gas composition in the other leg is lean so that the combined gas stream is always lean and reductant slip is oxidized in the oxidation catalyst.
