FIELD: chemistry.

SUBSTANCE: invention relates to the technology of producing nickel-based catalysts stabilised with active aluminium oxide, and can be used in chemical industry for fine purification of hydrogen-containing gases from carbon oxides via catalytic hydrogenation to methane. The method involves one-, two-, three or four-fold soaking of a support in nickel nitrate solution with concentration of 200 g/l based on active aluminium oxide in form of spheres of diameter 2-5 mm; the support is pre-calcined at temperature of 700°C. Soaking is followed by drying at temperature of 100-120°C and calcination at temperature of 450-500°C. The support is then soaked in ammonium carbonate solution with ammonia concentration of 100-120 g/l, CO₂ - 90-100 g/l, dried at temperature of 100-120°C and calcined at temperature of 450-500°C. The finished catalyst contains 15-30% nickel oxide.

EFFECT: catalyst has high activity, heat stability and mechanical strength.
