FILTER WITH FLOW ON WALLS FOR CLEANING DIESEL ENGINE EXHAUST GASES, DIESEL ENGINE EXHAUST GAS SYSTEM CONTAINING SAID FILTER, AND METHOD FOR CATALYTIC CLEANING EXHAUST GASES FROM DIESEL FUEL COMBUSTION

摘要

FIELD: chemistry. ^ SUBSTANCE: filter is made from sintered silicon carbide particles on whose surface there is porous titanium dioxide layer. A catalytically active material of the following composition is deposited on the porous titanium dioxide layer: 20-50 g V2O5 per litre of the filter, 1-50 g WO3 per litre of the filter, 0.25-1 g Pd per litre of the filter, up to 2 g Pt per litre of the filter. The invention also relates to an installation for releasing diesel engine exhaust gases containing the said filter. ^ EFFECT: high degree of purity of exhaust gases, longer catalyst life. ^ 7 cl, 3 ex, 4 tbl, 4 dwg
