An exhaust gas processing apparatus for a paint drying oven of this invention comprises a reaction container; a first catalyst layer disposed at an upstream side of the reaction container comprising a support of a honeycomb substance or a foamed substance, a carrier layer formed on the support and a platinum group element catalyst loaded on the carrier layer; a second catalyst layer disposed downstream of the first catalyst layer comprising a support of a pellet substance, a honeycomb substance or a foamed substance and a platinum group element catalyst; and a third catalyst layer disposed downstream of the second catalyst layer comprising a support, a carrier layer formed on the support and a copper-cerium-silver catalyst loaded on the carrier layer. Thus, the exhaust gas processing apparatus of this invention exhibits improved exhaust gases purifying abilities, even at relatively low temperatures, and less pressure drop.

Exhaust gas processing apparatus for paint drying oven

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.

Catalytic combustion type exhaust gas processing device and drying

A catalyst for decomposing an offensively smelling substance such as aldehydes by oxidation and a method which employs it for removing the offensively smelling substance. The catalyst comprises copper, cerium and silver supported on a porous ceramic carrier and is contacted with an offensively smelling substance to decompose it. The catalyst is particularly effective for decomposing aldehydes.
