METHOD OF PREPARING SULFUR-CONTAINING CARBON SORBENT

摘要

carbon sorbents. SUBSTANCE: starting activated carbon material, in particular natural-origin or synthetic carbon fibers and/or macroporous coals, is subjected to single-step treatment with hydrogen sulfide at 200 to 700 C until saturation of carbon material with hydrogen sulfide is completed. EFFECT: increased selectivity with regard to a series of metals prone to form low-soluble sulfides, mainly halcophilic elements. 4 cl, 1 tbl, 2 ex
