METHOD OF PREPARING GRANULATED SORBENT CATALYST Russian patent published in 1997 - IPC

Abstract RU 2097126 C1

FIELD: sorbents for gas treatment. SUBSTANCE: invention relates to sorbents for removing sulfur compounds (sulfur dioxide, hydrogen sulfide, mercaptans) from release gases at chemical, metallurgical, pulp-and-paper etc. enterprises. Method includes mixing raw material with binder, granulation, carbonization, and activation. As raw material, dry concentrate of sulfite-alcohol distillery dreg and, as binder, sulfite-alcohol distillery dreg with 50% content of solids are used. Carbonization is carried out at 350-400 C, mixing at 120-130 C. Ratio of dry to 50% distillery dreg is 3: (1-1.2). Activation is conducted at 750-800 C for 20-25 min. EFFECT: enhanced efficiency of process. 3 cl, 1 tbl
