Abstract
PURPOSE:To reduce the deposition of ammonium sulfate or the like on a catalyst surface and improve activity at low temp. by contg. titanium oxide, oxide of metals such as vanadium and inorg. fibrous materials as a catalyst for removing nitrogen oxide. CONSTITUTION:At least one kind out of titanium oxide and oxide of metals such as tungsten, vanadium and other as well as inorg. fibrous materials of silica, inorg. glass, etc. are contained as a catalyst used for catalytic reduction of NOx in waste gas contg. SOx by NH3. When these are molded and fired after kneading, fine pores of large diameters disperse uniformly in a large amount in the catalyst, thereby preventing ammonium sulfate or acidic ammonium sulfate from depositing on the surface and improving catalyst activity at low temp.
