ZEOLITE PROMOTED V/Ti/W CATALYSTS Russian patent published in 2024 - IPC B01J23/22 B01J29/40 B01J29/65 B01J29/88 B01J29/70 B01J23/30 B01J21/06 B01D53/94 

FIELD: catalytic chemistry.

SUBSTANCE: catalytic composition for exhaust gas purification is proposed containing a mixture of the first component and the second component, where the first component is an aluminosilicate molecular sieve component, where the molecular sieve has a structure selected from MFI, BEA and FER and where the molecular sieve is in H+ form, and the second component is vanadium oxide deposited on the metal oxide carrier is made of titanium oxide, while the second component additionally contains tungsten oxide, where the first and second components are present in the mixture in the corresponding mass ratio from 5:95 to 40:60. A porous catalytic coating, a catalytic product, an exhaust gas purification system and an exhaust gas purification method are also proposed.

EFFECT: provision of a catalyst that provides improved high-temperature parameters, improved hydrothermal stability, high sulfur resistance and improved resistance to NO2 compared to known SSR catalysts and ASC catalysts.
