Abstract
A catalytic combustion type exhaust gas processing device wherein noxious/smelly components contained in exhaust gases are deodorized and purified through sequential oxidative decomposition by at least one catalyst layer composed of platinum and/or palladium catalyst and a copper-cerium catalyst comprising chemically active species of copper and cerium in a compounded form. The device can be applied effectively to a drying furnace, for example, used in a coating for automobile use.
