Abstract
PURPOSE: To produce a catalyst showing high activity for the purification of exhaust gas, comprising impregnating a carrier with an aqueous solution containing noble metal, elevating the temperature of the carrier in the wetted state by means of electromagnetic wave, and passing gas to be treated into pores of the carrier while further heating the carrier by means of electromagnetic wave, to deposit the noble metal on the carrier.
CONSTITUTION: A heat-resistant united structure type carrier having alumina film previously formed, is impregnated with a solution of catalytic metal compound such as platinum, platinum-rhodium. The carrier in the wetting state is heated for a short time by means of electromagnetic wave to elevate the temperature of the carrier. While further heating the carrier by means of electromagnetic wave, gas to be treated such as hydrogen sulfide gas, ammonia gas is passed into pores of the carrier at a flow rate of above 5cm/min., thereby the noble metal is uniformly deposited on the carrier. Thus, a catalyst showing high activity for the purification of exhaust gas of internal combustion engine can be obtained.
