FILTER FOR REMOVAL OF EXHAUST GAS PARTICLES RELEASED FROM ICE WITH FORCED IGNITION Russian patent published in 2014 - IPC B01D53/94 B01J29/04 B01J35/04 B01J35/10 F01N3/35 

FIELD: process engineering.

SUBSTANCE: invention relates to filter for processing solid particles of exhaust gases of whatever combustion process. Filter comprises porous bed with intake and discharge surfaces. Note here that said surfaces are separated by porous structure with pores of the first average size. Note also that said porous structure is coated with coating including multiple solid particles. Note that porous substrate porous structure comprises pores of second average size smaller than that of the first average size. Mind that said coating is a catalytic coating selected from the group consisting of hydrocarbon trap, three-component catalyst, NO_x absorber, oxidising catalyst, catalyst of selective catalytic reduction and catalyst for lean NO_x. Note also that three-component catalyst comprises platinum and rhodium, palladium and rhodium or platinum, palladium and rhodium on substrate of oxide with high surface area, and component for oxygen store.

EFFECT: efficient cleaning.
