ABSTRACT:
This invention provides a catalyst for purifying exhaust gases of a diesel engine, said catalyst comprising at least one element selected from nickel and cobalt and optionally a copper element. Further, this invention provides a catalyst for purifying exhaust gases of a diesel engine, said catalyst comprising a refractory three-dimensional structure and deposited thereon a catalyst component comprising the above elements and a refractory inorganic oxide. These catalysts can remove harmful ingredients contained in exhaust gases of a diesel engine, such as carbonaceous fine particles, unburned hydrocarbons, carbon monoxide, etc. by burning from low temperatures and suppress sulfate formation from sulfur dioxide.
