Abstract

An account is given of the more academic aspects of the research work carried out in Germany and elsewhere during the war years, and on this basis a picture of the catalyst and its method of working is developed. The reacting gases reach the catalyst surface directly in atmospheric pressure synthesis, but by solution in and diffusion through the wax that fills the pores of the catalyst in medium pressure synthesis. The cobalt atoms appear to be isolated and do not form part of a cobalt lattice. Reaction by way of chemisorbed carbon atoms‐surface carbide‐is thought to give an array of inter‐acting methylene groups on the surface, and the composition of the products, which are obtained by desorption from this array, depends on the conditions.
