The catalyst comprises magnesium oxide as a support, two or three metal oxides selected from the group consisting of ferric oxide, cobalt oxide, and nickel oxide as a complex metal oxide composite, lanthanum ... 10/05/06 - 20060223697 - Catalyst for removal of carbon monoxide A catalyst for removal of carbon monoxide from a hydrogen-containing gas that contains carbon monoxide, is provided. The catalyst includes a metal oxide-containing carrier, and a ruthenium component and a lanthanide component both supported on said carrier. Carbon monoxide can be removed from the hydrogen-containing gas with methanation reactions suppressed ... 06/15/06 - 20060128562 - Exhaust gas purification catalyst Catalytic converter comprises a carrier having exhaust gas passages therein, a lower catalytic layer coated over the carrier and comprising hollow oxide powder loaded with catalytic metal, and an upper catalytic layer coated over the lower catalytic layer, directly exposed to exhaust gas flowing in the exhaust gas passages and ... 04/27/06 - 20060089255 - Exhaust gas purifying catalyst and exhaust gas purifying device therewith for vehicle An exhaust gas purifying catalyst which exhibits sufficient efficiency during low temperature operation (below 400° C.) such as starting of a vehicle or idling operation can be provided by improving activation of a noble metal itself and preventing reduction of activation at high temperatures. In the catalyst, Pd is supported ... 10/20/05 - 20050233898 - Modified catalyst supports A modified catalyst support exhibiting attrition resistance and/or deaggregation resistance is provided. A catalyst composition including the modified catalyst support is also provided. A process to produce a modified catalyst support including treatment of a support slurry with a solution of monosilicic acid is provided. A process to use a ... 07/14/05 - 20050153835 - Modification catalyst composition Disclosed is a reforming-catalyst composition, which comprises nickel oxide and lanthanum oxide as a catalytic material for inducing a reaction between stream and either one of methane, natural gas and town gas to produce a hydrogen-containing gas. The nickel oxide and lanthanum oxide are formed as a perovskite-structured compound partly ... 06/02/05 - 20050119119 - Water gas shift catalyst on a lanthanum-doped anatase titanium dioxide support for fuel cells application A stable water gas shift catalyst comprising platinum, rhenium and lanthanum on an anatase titanium dioxide support is described. The catalyst of the present invention is at least as efficient in converting CO to CO2 at low temperatures as the catalysts of the prior art. Further, the catalyst is about ... 06/02/05 - 20050119118 - Water gas shift catalyst for fuel cells application A stable water gas shift catalyst comprising platinum, rhenium and lanthanum on a high surface area rutile titanium dioxide support is described. The catalyst of the present invention is at least as efficient in converting CO to CO2 at low temperatures as the catalysts of the prior art. Further, the ... ### FreshPatents.com Support |
