FIELD: chemistry.

SUBSTANCE: invention relates to methods of producing catalysts for oxidising carbon monoxide. Described is a method of producing a porous granular catalyst for oxidising carbon monoxide, involving mixing functional oxides, including manganese dioxide, obtained from chemical reaction of reactants, wherein the mixture is put into a porous frame having the shape of granules, wherein the porous frame used is silica gel granules saturated with iron, cobalt and manganese oxides via step-by-step impregnation with aqueous solutions of metal salts with inter-operation drying in the following sequence: first step - separate impregnation with iron sulphate and cobalt nitrate, each conjugated with the last impregnation of porous granules with potassium hydroxide solution in ethyl alcohol, and the formed metal hydroxides are then thermally decomposed to end iron and cobalt oxides; second step - separate impregnation with potassium permanganate and sodium hyposulphite, thereby saturating porous granules of the formed manganese dioxide; the obtained mixture of said metal oxides then undergoes final washing and the ready powdered product is then dried.

EFFECT: efficient, highly stable carbon monoxide oxidation catalyst is obtained.
