An assessment has been made of the activity of a planar metal-based catalyst with a supported active component in the surface layer in the separate hydrogenation of carbon oxides in high concentrations in a continuous unit at atmospheric pressure. The kinetics of these processes has been investigated. It has been shown that, at temperatures ranging from 450 to 600 degrees C, the catalyst ensures practically equilibrium degrees of conversion of carbon oxides to methane with volume feed rates of 15,000 hr(-1). A kinetic equation has been found which describes the experimental data. The values of the apparent activation energy have been calculated.
