    摘要： The composition based on a discharge from an oil refining plant after a desulfurization of heavy oils in the oil refining plant using a catalyst, comprising: 80% or less of vanadium; 80% or less of molybdenum; 20% or less of nickel; 30% or less of cobalt; 99% or less of alumina; and a trace of the impurities, which is catalytically active to purify the exhaust of diesel vehicles. A filter or a washcoat made of the discharged catalyst composition alone or in combination with ordinary filtering materials or ordinary washcoat materials can be very useful for purification of smoke. In addition, a catalyst in which at least one metal of the platinum group is uniformly impregnated on the filter is quite superior to conventional ones employing alumina or titania as a washcoat in stability to both high temperature and sulfur trioxide.

The process for preparing the amorphous perovskite structure catalysts comprises dissolving completely at least two salt solutions of metals, M.sup.1, M.sup.2, M.sup.3 and M.sup.4, and an acid in an organic acid, preparing an ester type resin intermediate by adding a hydroxy alcohol to the solution, mixing the solution in a liquid state by adding a powder type carrier material, distilling the mixed solution under a reduced pressure so as to concentrate the solution into a high viscous state, drying the concentrated solution using a microwave into a gel type catalyst precursor, and calcining the precursor stepwise at the temperatures of 300.degree..about.700.degree. C. The process can provide amorphous perovskite structure catalysts having a high specific surface area and a good dispersion for denitrizing nitrogen oxides.
