Some of the existing literature concerning catalyst poisoning has been reviewed. The review concentrates on chemical deactivation involving a chemically induced change in the catalyst's activity for metal or metal oxide catalysts used in gas-solid reaction systems. Mechanisms and kinetics of the reactions are discussed at the level of detail necessary to describe the phenomenon involved. Mathematical models are also derived to explain the poisoning mechanism. The development of automobile exhaust catalysts is reviewed as an example of how careful analysis of complex catalyst poisoning events and the resultant understanding of the mechanism of poisoning can significantly improve the design of commercial catalysts. 239 references.
