Hydrogenation of oxides of C is effected by passing a gaseous mixture of H₂ and CO under reaction conditions of temperature and pressure through a narrow space between 2 concentric, relatively smooth surfaces composed of Fischer-Tropsch synthesis catalyst. The inner surface is rotated in such a manner and the reaction zone is of such cross section and length that the desired throughput and space velocity are maintained with nonturbulent, eddylike flow. A substantially uniform temperature is maintained throughout the reaction zone by removing the exothermic heat through the walls. One of the walls may be transparent to light of a catalyzing wavelength.
