FIELD: chemistry.
SUBSTANCE: claimed is a synthetic alumosilicate zeolite catalyst, containing copper as a catalytically active component. The catalyst contains alumosilicate zeolite of a chabazite type. The maximal size of the zeolite ring constitutes eight tetrahedral atoms. The average size of zeolite crystals, determined by scanning electronic microscopy, constitutes more than 0.50 micrometer.
EFFECT: invention provides an increased selectivity of the reduction of nitrogen oxides in exhaust gases of internal combustion engines.
