A process is provided for destroying organic contaminants, such as oil mists from workshop rooms, formaldehyde and aromatics, out of exhaust gases by passing the exhaust gas through two reactors connected in a parallel arrangement to a contaminated exhaust gas inlet. Each of the two reactors is equipped with a plurality of serially arranged reaction zones, wherein each reaction zone contains an upstream catalyst (such as a commercial wire knit catalyst); a downstream absorbent (such as Y zeolite or H-ZSM) and a heater. A major portion of the contaminated exhaust gas is passed through one of the two reactors, while, simultaneously, a minor portion of the contaminated exhaust gas is passed through the other reactor. After a period of time, the exhaust gas flow rate through the two reactors is reversed so that a major portion of the exhaust gas now flows through the reactor that previously had a minor portion of the exhaust gas flowing through it and a minor portion of the exhaust gas now flows through the reactor that previously had a major portion of the exhaust gas flowing through it, so that the process is cyclical in this manner. When a major portion of the exhaust gas flows through a reactor, the hydrocarbon contaminants are sorbed into the absorbent. When a minor portion of the exhaust gas flows through a reactor, the reactor is heated to the catalyst light-off temperature so that the contaminants within the exhaust gas and the contaminants released from the absorbent are catalytically destroyed in a downstream catalyst in an adjacent downstream reaction zone.
