ADSORBENT FOR PROTECTION FACILITIES Russian patent published in 2004 - IPC

FIELD: sorbents. SUBSTANCE: invention relates to production of carbon-based adsorbents, in particular those adsorbing organic vapors (benzene, toluene, cyclohexane, etc. ), inorganic gases and vapors (sulfur hydride, hydrogen cyanide, chlorine, etc.), acid gases and vapors (sulfur dioxide, hydrogen chloride, hydrogen fluoride, etc.), and ammonia in protection facilities. Adsorbent based on impregnated activated carbon is a mechanical mixture composed of two constituents, the first constituent (45-55 vol %) containing copper oxides 0.5-10.0% (calculated as copper) and sodium and/or potassium carbonate 3.0-17.0% and the second one (55-45 vol %) containing copper sulfate 12.0-15.0%. Carbon base utilized is activated carbon prepared from nut shell and/or fruit stone. EFFECT: prolonged protection time. 2 tbl
