A study has been made of the heats of adsorption and the adsorption isotherms of saturated and unsaturated hydrocarbons on Co at 298/sup 0/K; the content of organic matter in the catalyst has been determined after use in the Fischer-Tropsch synthesis. It is concluded that the Fischer-Tropsch process includes stages of diffusion of the original reactants and the products through a liquid film of hydrocarbons coating the catalyst; the hydrocarbon molecules are adsorbed on the surface in the ''lying down'' position; the adsorption of paraffins is reversible and is described by the BET theory; olefins form an irreversibly chemisorbed monolayer, above which reversible adsorption takes place; the ease of desorption of the paraffins explains their preferential formation in the Fischer-Tropsch synthesis.
