EXTRUDED SCR-FILTER Russian patent published in 2015 - IPC B01D53/94 F01N3/00 C04B35/16 C04B35/63 

FIELD: process engineering.

SUBSTANCE: invention relates to filters with leaking through the walls including the extruded solid bulk and can be used for processing of nitrogen oxide in ICE used gas emission. Claimed filter comprises the catalyst for conversion of nitrogen oxide in the medium of reducing agent and extruded solid bulk. The latter contains the components that follow: 10-100 wt % of at least one binder/matrix component, 5-90 wt % of zeolite molecular screen, molecular screen other than zeolite or the mix thereof, and 0-80 wt % of cerium oxide, optionally stabilised. Said catalyst contains at least one metal present in said extruded solid bulk.

EFFECT: efficient purification of exhaust gases of ICE, stationary and mobile emissions sources, higher engine output and better mass transfer.
