Abstract

The formation of coke during hydrocarbon transformations over acid zeolite catalysts has important practical consequences for a growing number of industrial processes. This review presents available material on the formation, nature and properties of coke in high silica zeolite catalysts, and on the resulting deactivation and regeneration of the catalysts. Techniques for analyzing and characterizing coke, the role of acid sites in coke formation and the chemistry of coke formation are discussed, with particular emphasis on the methanol to gasoline process.
