FIELD: chemistry.
SUBSTANCE: catalytic product for exhaust gas processing contains a) a catalytic composition including an aluminosilicate molecular sieve with AEI structure, average crystal size between 0.1 and 15 mcm, not essentially containing halogens, from 1 to 5 wt.% of promoting metal per the total weight of molecular sieve material, and a binder including a component selected from alumina, silica, non-zeolitic silica-alumina, titanium dioxide, zirconium dioxide, cerium oxide, and b) solid particle filter, on which and/or to which the specified composition is placed.
EFFECT: obtaining improved selective catalytic reduction (SCR) catalysts that are capable of withstanding higher temperatures with low degree or without deactivation.
