This utility model refers to chemical industry, in particular to obtaining zeolite catalyst that can be used for purifying toxic agents - nitrogen and carbon oxides in exhaust gases both in the internal combustion engine and in any industrial enterprise. Technical result is the possibility of long-term work of the catalyst. The method comprises three-fold treatment of natural zeolite by means of 0,3 - 0,5 NHCL during one hour, CL¯ washing to the negative reaction, drying, three-fold treatment by the copper salts solution, washing with distilled water, drying and pressing for obtaining granules, the proportion of zeolite and acid being 1:4:6. 1 tabl.
