FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing a methanation process catalyst, which includes impregnating a support based on active aluminium oxide in the form of granules in a solution containing nickel nitrate, followed by drying at temperature of 100°C-120°C and calcining the impregnated support at temperature of 450°C-500°C, wherein a modification additive - an organic acid with concentration of 0.5-20.0 wt % - is added to the nickel nitrate solution, and the finished catalyst contains NiO monocrystallites with mean sampling size in the range of 2-3 nm, with concentration of NiO of 12.0-25.0 wt % and γ-Al2O3 - the balance.
EFFECT: high reliability and activity, low cost and faster implementation of the method.
