FIELD: separation of gases from carbon oxides. SUBSTANCE: aluminium-platinum or aluminium palladium catalysts or their mixtures are treated with peptizer-mineral acid. The mass obtained is mixed with active ingredient. Mixture of oxides of transition metals with compounds of promoting additives serves as such active ingredient. The amount of the additives selected from the chloride of fluoride group of the above metals or their mixtures is 0.3-2.0 percent of mass. The mass obtained is molded to produce granules afterwards. Granules are put for drying and heated for 2-4 hours at 400-500 C. EFFECT: higher efficiency. 1 tbl
