  • Patent number: 8921258
    Abstract: Disclosed is a catalyst which can convert ammonia contained in exhaust gas from an engine of a vehicle equipped with a Urea-SCR (Urea-Selective Catalytic Reduction) system, to nitrogen, and a method for preparating the same. The catalyst can convert ammonia which is failed to participate in a conversion reaction of NOx to N2 and slipped out of the SCR catalyst, to nitrogen via a SCO (Selective Catalytic Oxidation) reaction, before the ammonia is released to the air.

  • Patent number: 8883100
    Abstract: The present invention relates to a particle filter comprising a porous carrier body, an SCR active component and an oxidation catalyst, wherein the SCR active component is present as coating on the exhaust-gas entry surface and the inner surface of the porous carrier body and the oxidation catalyst as coating on the exhaust-gas exit surface of the porous carrier body. According to the invention the oxidation catalyst changes its function depending on operating conditions. In normal operation it serves as NH3 slip catalyst for oxidizing excess NH3 and during filter regeneration it operates according to the 3-way principle for converting NOx and CO. The invention also relates to a method for producing the particle filter, the use of the particle filter for treating exhaust gases from the combustion of fossil, synthetic or biofuels as well as an exhaust-gas cleaning system which contains the particle filter according to the invention.

  • Patent number: 8877674
    Abstract: Carbon monoxide (CO) is selectively reacted with hydrogen (H2) over a ruthenium (Ru) on alumina catalyst at a temperature of about 210 to about 290° C. To be a viable option for micro catalytic fuel processing devices, highly active, selective, and stable catalysts must be demonstrated with as large a temperature window for feasible operation as possible. We have studied the effects of metal loading, preparation method, pretreatment conditions, and choice of support on the performance of Ru-based catalysts for such applications. Catalyst testing results and catalyst characterization using XRD and BET are discussed. In one example, operating at a gas hourly space velocity (GHSV) of 13,500 hr?1, a 3% Ru/Al2O3 catalyst yielded CO outputs less than 100 ppm in a temperature range from 240° C. to 285° C., while not exceeding a hydrogen consumption of 10%. This catalyst was further successfully demonstrated in a microchannel device.
