FILTERING-SORBING MEMBER FOR AIR CLEANING MEANS Russian patent published in 2003 - IPC

FIELD: sorption technology; applicable in devices for air cleaning from harmful production processes. SUBSTANCE: filtering-sorbent member consists of sorbent particles interconnected by uniformly distributed thermoplastic polymer particles with average size if 0.15-0.7 of average size of sorbent particles. Filtering-sorbing member consists of front and terminal layers. Front layer contains sorbent in the form of mixture of carbon-containing catalyst modified with compounds of copper, chromium, silver and triethylenediamine, aluminum active oxide impregnated with barium permanganate at the following ratio of components in layer, mas.%: carbon-containing modified with compounds of copper, chromium, silver and triethylenediamine, 45-65; aluminum active oxide impregnated with barium permanganate, 15-45; thermoplastic polymer, 7-30. Terminal layer consists of mixture of aluminum active oxide impregnated with palladium and thermoplastic polymer, at the following ratio of components in layer, mas.%: aluminum active oxide impregnated with palladium, 48-93; thermoplastic polymer, 7-52. EFFECT: effective air cleaning from harmful impurities, products of their decomposition and motor fuels. 2 tbl
