Abstract
Publisher Summary This chapter discusses Fischer–Tropsch synthesis (FTS), which consists of complex syngas reactions occurring with metallic, though not necessarily pure metal, catalysts. The Fischer–Tropsch-type reactions lead to very broad product distributions, including alkanes, alkenes, oxygen-containing derivatives, CO 2 , and H 2 O. The components involved in the FTS are hydrogen, hydrocarbons, and carbon monoxide. Adsorption characteristics of pure components and the adsorption features of mixtures are of importance. All metals active in hydrocarbon synthesis adsorb hydrogen at low temperatures up to full coverage. The hydrogen/surface atoms ratio can reach one, which can be also possible among other metals derived from the phase diagrams of H 2 adsorption on single crystals. Adsorption on clean surfaces is fast, nonactivated, and dissociative. There is always atomically dispersed carbon on the metal surfaces, or a two-dimensional carbide sets in which it is sufficiently reactive to play the role of an intermediate in the FTS. The faster it can react with hydrogen, the lower the probability that it will coagulate and deactivate on the surface or become dissolved in the bulk.
