FIELD: chemistry.
SUBSTANCE: invention relates to chemical industry. Hydrocarbon process gas after desulphurisation in a mixture with steam is fed into heated heat-resistant pipes, inside of which there is a nickel-containing catalyst in the form of a layer of granules in the shape of a sphere or cylinder with a surface area of 400-700 m2/m3 and porosity of 0.5-0.7 m3/m3. The granules contain parallel cylindrical channels with the ratio of the diameter of the granule to the diameter of the channel of the cylinder or sphere ranging from 4.0 to 6.0. The ratio of the internal diameter of the heated pipe of the reactor to the diameter of the cylinder or sphere of the catalyst ranges from 4.0 to 12.5.
EFFECT: invention reduces differential pressure on the catalyst layer and residual content of methane in the obtained synthesis gas.
