OXYDATION CATALYST Russian patent published in 2014 - IPC B01J23/38 B01J35/04 B01J37/04 B01J37/08 B01J23/63 B01D53/94 C04B35/16 C04B35/18 

FIELD: chemistry.

SUBSTANCE: described is oxidation catalyst, which includes extruded solid material, containing: 10-95 wt % of, at least, one matrix-binding component; 5-90 wt % of synthetic alumosilicate zeolite molecular sieve or mixture of any two or more of such sieves, each of which has 10-ring pore structure or larger than 10-ring pore structure as its largest structure of pore holes, and has ratio of silicon dioxide and aluminium oxide constituting from 10 to 150; and 0-80 wt % of optionally stabilised cerium dioxide, with catalyst containing, at least, one precious metal and, optionally, at least, one non-precious metal, in which (1) main mass of, at least, one precious metal is located on the surface of extruded solid material; (ii) at least, one precious metal is applied in one layer or several layers on the surface of extruded solid material; (iii) at least, one metal is present in volume of extruded solid material and is present in higher concentration on the surface of extruded solid material; (iv) at least, one metal is present in volume of extruded solid material and is applied in one layer or several layers on the surface of extruded solid material; or (v) at least, one metal is present in volume of extruded solid material, is present in higher concentration on the surface of extruded solid material, and is applied in one layer or several layers on the surface of extruded solid material. Described are method of claimed catalyst manufacturing, method of processing emissions of waste gases of combustion engines, and system of discharge of gases and vehicle.

EFFECT: catalyst improvement.
