FIELD: process engineering.

SUBSTANCE: invention relates to low-temperature conversion of blue gas by conversion of CO and H₂O in gas flow into CO₂ and H₂ in the presence of catalyst. Proposed method comprises bringing said gas flow in contact with reduced catalyst under reaction conditions of blue gas low-temperature conversion. Said catalyst is produced from catalyst containing 5 to 75 wt % of copper oxide, 5 to 70 wt % of zinc oxide and 5 to 50 wt % of aluminium oxide with dispersity factor of 40% or higher for water after peptisation at pH of about 2 to about 5. Invention covers also the conversion with blue gas conversion catalyst from dispersed aluminium oxide and precipitated copper and zinc compound produced by the process including: (a) addition of dispersed aluminium oxide suspension to solution of copper and zinc salts to get suspension of aluminium oxide and copper and zinc salts; (b) preparing aqueous solution of alkali metal carbonate; (c) combining aluminium oxide suspension and solution of copper and zinc salts and alkali metal carbonate solution with water to form precipitate to be oxidised; (d) precipitate filtration washout, drying and calcining to form blue gas conversion catalyst; (e) reduction of said catalyst in hydrogen-bearing gas to produce reduced blue gas conversion catalyst.

EFFECT: higher activity of catalyst.
