Abstract
Abstract The mechanism of Fischer-Tropsch synthesis of hydrocarbons by catalytic hydrogenation of carbon monoxide has not as yet been definitively resolved, even though considerable advances have been made. This article outlines the origin and development of the main ideas on the initiation, build-up and termination of the synthesized hydrocarbon chains. The original theory of the synthesis, involving carbidic surface intermediate, and objections against it are discussed. An account is given of its temporary rejection in the 1950s in favour of the theory of oxygenated surface intermediates. The arguments leading to the rehabilitation of the carbide theory in the mid-1970s and the current mechanistic views are presented.
