20160129430 | OXIDATION CATALYST FOR EXHAUST GAS PURIFICATION, METHOD FOR PRODUCING THE SAME, AND EXHAUST GAS PURIFICATION METHOD USING THE SAME - The purpose of the present invention is to provide an oxidation catalyst for exhaust gas purification having high durability and a method for producing the catalyst. The purpose is achieved by an oxidation catalyst for exhaust gas purification containing a refractory inorganic oxide, and a catalyst component and a metal component, which are supported on the refractory inorganic oxide, wherein the catalyst component is platinum, or platinum and palladium, and the metal component is one or more selected from the group consisting of magnesium, calcium, strontium and barium. | 05-12-2016 |
20140072493 | CATALYST FOR EXHAUST GAS PURIFICATION, METHOD FOR PRODUCING THE SAME, AND EXHAUST GAS PURIFICATION METHOD USING THE SAME - The purpose of the present invention is to provide a catalyst for exhaust gas purification, which is capable of effectively processing an exhaust gas, particularly carbon monoxide (CO) and hydrocarbon (HC) in the exhaust gas at a low temperature, and a method for producing the catalyst for exhaust gas purification. The purpose is achieved by a catalyst for exhaust gas purification, which is obtained by having a carrier that contains Al | 03-13-2014 |
