|20120027654||CATALYST FOR PURIFICATION OF EXHAUST GAS||02-02-2012|
|20110027155||CATALYST FOR CLEANING INTERNAL COMBUSTION ENGINE EXHAUST GAS AND METHOD FOR CLEANING EXHAUST GAS USING SAID CATALYST - An Object of the patent is to remove highly reducing hydrocarbon exhausted during acceleration period, and to remove efficiently hydrocarbon even after contacting with highly reducing hydrocarbon. By using a catalyst having a higher proportion of palladium having surface charge of 2-valence or 4-valence supported than that of 0-valence by supporting palladium together with magnesium oxide, hydrocarbon exhausted from an internal combustion engine especially during acceleration period can be efficiently removed.||02-03-2011|
|20100260652||Catalyst for the removal of nitrogen oxides and method for the removal of nitrogen oxides with the same - The present invention provides a catalyst which can sufficiently remove nitrogen oxides in an exhaust gas. The catalyst for removing nitrogen oxides to achieve an object of the present invention includes a monolithic support which is coated with a lower layer containing a catalytic component A comprising cerium oxide and an upper layer containing a catalytic component B comprising at least one kind of metal selected from a group consisting of copper, manganese, iron, cobalt and nickel or a compound thereof, and zeolite.||10-14-2010|
|20100150800||Oxidation catalyst and exhaust-gas purification system using the same - An oxidation catalyst that efficiently promotes oxidation of NO to NO||06-17-2010|
|20090107122||METHOD FOR PURIFICATION OF EXHAUST GAS FROM INTERNAL COMBUSTION ENGINE - Temperature range enabling combustion of high concentration hydrocarbon is enlarged, or high temperature gas is rapidly supplied to a latter part catalyst. Provided is a method for purification of exhaust gas from an internal combustion engine, by using a catalyst for increasing temperature of exhaust gas from an internal combustion engine, wherein hydrocarbon from 1,000 to 40,000 ppm by volume, as converted to methane, to the exhaust gas, is introduced at the upstream side of the catalyst for increasing temperature, along flow of the exhaust gas inside a passage of exhaust gas from the internal combustion engine.||04-30-2009|
|20090056318||Method and device for controlling exhaust emission from internal combustion engine - The present invention provides a purification method excellent also in removing particulates or the like from exhaust gas from an internal combustion engine, in particular, a diesel engine or the like. A purification method for exhaust gas from an internal combustion engine, wherein said purification method uses an exhaust gas purification apparatus comprising an oxidation zone installed with an oxidation catalyst supporting both platinum and palladium, and a filtering zone installed with a particulate filter, along exhaust gas flow at the exhaust gas passage of an internal combustion engine, characterized in that hydrocarbon-based liquid is supplied to the inflow side of the exhaust gas of said oxidation zone at the time when 2 to 10 g of particulates per 1 litter of said particulate filter are caught, to raise temperature of said exhaust gas up to equal to or higher than 550° C. by said oxidation catalyst so as to make the residue of said particulate filter combusted; and an apparatus thereof.||03-05-2009|
