20100080737 | EXHAUST GAS TREATMENT CATALYST AND EXHAUST GAS TREATMENT SYSTEM - Provided are an exhaust gas treatment catalyst capable of reducing ammonia leakage rate while keeping a sufficient NO | 04-01-2010 |
20100192552 | EXHAUST GAS TREATMENT CATALYST, EXHAUST GAS TREATMENT METHOD, AND EXHAUST GAS TREATMENT APPARATUS - An exhaust gas treatment catalyst for removal of one or more pollutants in an exhaust gas, the catalyst comprising: a SO | 08-05-2010 |
20120171097 | CATALYST FOR TREATING EXHAUST GASES, METHOD FOR PRODUCING THE SAME, AND METHOD FOR TREATING EXHAUST GASES - A catalyst for treating exhaust gases containing nitrogen monoxide, carbon monoxide and volatile organic compounds includes a plurality of layers, an upper layer of which has an active component contained uniformly therein and a lower layer of which has no active component contained therein. The catalyst is obtained through the steps of: forming the lower layer by coating the surface of substrate with a slurry of a porous inorganic compound, followed by drying; and forming the upper layer, which is to be the top surface of the catalyst, by coating the surface of the lower layer with a slurry of a porous inorganic compound that has the active component composed of one or more precious metals supported thereon, followed by drying. The oxidation power of the resulting catalyst is enhanced without increasing the amount of precious metal supported thereon. | 07-05-2012 |
20120225772 | SO3 REDUCTION CATALYST FOR PURIFYING AN EXHAUST GAS, PREPARATION PROCESS THEREOF, AND EXHAUST GAS PURIFYING METHOD USING THE CATALYST - In the catalyst for purifying a combustion exhaust gas containing nitrogen oxides, 50 wt. % or greater of the amount of Ru and/or Ir to be supported is adjusted to fall within a depth of 150 μm from the surface layer of a substrate; and the catalyst is prepared by immersing the substrate in a metal colloid solution of Ru and/or Ir to be supported or an aqueous solution containing at least one compound selected from compounds of Ru and/or Ir to be supported. | 09-06-2012 |
