摘要： A nitrogen oxide removing catalyst has a porous material having fine holes with controlled diameters and a catalyst having an active ingredient supported in the fine holes are used. In one instance, the diameter of the plurality of fine holes is within a range of 8-9 Å. The fine hole diameter is preferably from 8-9 Å when the diameter is measured in a gas adsorption method in which fine holes with diameters of 3.4-14 Å can be measured. The fine hole diameter is also preferably from 8-9 Å when the fine hole diameter is calculated from a crystal structure. In another instance, the porous material is mesoporous silica. The primary particle diameter of the mesoporous silica is preferably within a range of 150-300 nm. The nitrogen oxide removing catalyst having superior durability and a method of removing nitrogen oxides are also provided.

摘要： The invention realizes a catalyst which is hardly deteriorated even when volatile catalyst-poisoning compounds such as P and As are accumulated and which can reduce the rate of oxidation of SO2 to a level as low as a fraction of that of the catalyst in the prior art, and provides an exhaust gas purification catalyst which can maintain a high activity and a low rate of oxidation of SO2 for a long time even with any diversified coal, a method of producing the same, and an exhaust gas purification method using the same. Disclosed is an exhaust gas purification catalyst having a composition comprising oxides of titanium (Ti), molybdenum (Mo) and/or tungsten (W), vanadium (V) and bismuth (Bi), wherein the atomic ratio of Ti:(Mo and/or W):V is 75 to 98.9:1 to 0.1 to 10 and the atomic ratio of Bi/(Mo and/or W) is 0.1 to 0.8.

摘要： (1) A particulate material removing filter for an exhaust gas from a diesel engine, which has a laminate manufactured by laminating metal lath plates having an oxidation catalyst layer containing a noble metal for oxidizing NO in an exhaust gas into NO2, in such a manner that drawing directions in the preparation of respective said metal lath plates are alternately different by 90 degrees; (2) a method for treating an exhaust gas which comprises allowing a gas to be treated to flow into the above filter parallel with the metal lath plane of the laminate or in the direction intercepting to the metal lath plane of the laminate, to thereby clarify the exhaust gas from a diesel engine; and (3) an apparatus for treating an exhaust gas which has the above filter disposed at an outlet for an exhaust gas from an diesel engine. The filter is novel, can be manufactured with non-expensive materials, is less susceptible to clogging or closure by ash components, and does not require a special means such as reverse washing or the heating and burning of soot.
