<p>PROBLEM TO BE SOLVED: To provide a producing method of a catalyst in which dispersion with high dispensability of a catalytic component on a carrier is maintained and use of expensive processes of drying and calcining are avoided. SOLUTION: A powder mixture comprising a specified particulate material is impregnated by a pore volume impregnation method by using a soln. of a precursor compd. of th catalytic component so as to adsorb th precursor compd. on at least the particulate material. The impregnated powder mixture is used to prepare an aq. coating dispersion liquid, and the obtd. dispersion liquid is applied on a carrier, dried and calcined. Therefore, the catalyst can be produced at a low cost and desorption of the catalytic component from the carrier material can be avoided at the time when the carrier material is dispersed to prepare the coating dispersion liquid.</p> |
