METHOD OF OBTAINING CHEMOSORBENT Russian patent published in 2014 - IPC B01J20/20 C01B31/08 C01B31/16

Abstract RU 2510868 C1

FIELD: chemistry.

SUBSTANCE: invention relates to field of obtaining chemosorbents, which are applied for means of protection of respiratory organs and for purification of discharge gases. Method of obtaining chemosorbent includes impregnation of activated coal granules with modifying solution, maturing granules and their thermal processing. Active coal with volume of micropores 0.36-0.55 cm³/g is subjected to impregnation. Impregnation solution contains copper sulfate, water and sulfuric acid in ratio 1:(8-10):(0.3-0.5). Coefficient of impregnation constitutes 0.8-1.0.

EFFECT: invention makes it possible to increase duration of protective action of obtained chemosorbent by benzene with preservation of high adsorption activity.
