摘要：A catalyst composition for the vapor phase reduction of nitrogen oxides withammonia, which consists essentially of a non-noble transition metal compound supportedon a shaped carrier comprising a titanium oxide and a clay mineral having an averageparticle size of 0.1 to 100 microns. The shaped carrier preferably contains an additionalcomponent which is an inorganic fibrous material, silica hydrogel, silica sol, or a mixture ofat least two of these. An exhaust gas containing nitrogen oxides is treated, with a highpercent NO removal, by contacting it with the catalyst composition in the presence ofammonia gas at 200° to 600. degree. C.
