METHOD FOR PRODUCING CATALYTIC TISSUE FILTER AND CATALYTIC TISSUE FILTER Russian patent published in 2017 - IPC B01D39/08 B01J35/06 

FIELD: technological processes.

SUBSTANCE: method for manufacturing catalytic tissue filter comprises the steps of a) providing a tissue filter substrate, b) providing an aqueous impregnating fluid containing an aqueous hydrosol of one or more metal catalyst precursor compounds distributed on the metal oxide carrier nanoparticles, a dispersant comprising one or more primary amines, and a surfactant; c) impregnating the tissue filter substrate with a liquid for impregnating, and d) drying and thermally activating the impregnated tissue filter substrate at a temperature below 300°C to convert one or more metal catalyst precursor compounds to their catalytically active form.

EFFECT: optimum catalytic efficiency.
