METHOD FOR PRODUCING ADSORBENT OF CARBON DIOXIDE GAS Russian patent published in 1997 - IPC

FIELD: procedure for carrying out sorption processes. SUBSTANCE: burnt lime is slaked with 0.01-5.00%-aqueous solution of modifying agent selected from amongst ammonium chloride, acetic acid, spirit of ammonia and calcium chloride, the resulting mass is treated with coagulating agent selected from amongst ammonium chloride, acetic acid, sodium polyacrylate, calcium, formic acid, polyacrylamide, citric acid, magnesium chloride and lithium polyacrylate in amount of 0.01-4.50 wt.% dissolved in 40%-alkaline solution, amount of alkali constituting 10 wt.%. Mass thus-treated is stirred to achieve homogeneous paste-like condition, granulated, dried with dry steam, followed by impregnating resulting granular material with 0.00001-0.00500%-aqueous solution of polyacrylamide. EFFECT: proposed adsorbent effectively adsorbs carbon dioxide gas. 1 tbl
