The kinetics of hydrogenation of CO on potassium carbonate catalyst loaded on coal char activated carbon are investigated at elevated pressures up to 3.4 MPa and at temperatures in the range 773-923 K. The potassium carbonate catalyst is shown to be active enough for methane formation via the hydrogenation of CO. The methane formation rate data in this reaction are well represented by a Langmuir-Hinshelwood type rate equation on the basis of dual site mechanism including an adsorption term of CO molecule. The kinetic parameters in the rate expression are investigated in relation to temperature and catalyst content. It is implied that the hydrogenation of adsorbed (CH) species is the rate-determining step in the dissociative mechanism involving the formation of active carbon via the dissociation of CO molecule.
