GAS- AND LIQUID-TREATMENT ADSORBENT FOR REMOVING HALOGEN-CONTAINING COMPOUNDS AND A METHOD OF PREPARATION THEREOF

摘要

FIELD: sorbents. SUBSTANCE: adsorbent is composed of, wt %: zinc oxide 50.0-85.0, alkali metal compound 0.001-0.9 (on conversion to metal oxide), silicon compound 0.05-15.0 (on conversion to silicon dioxide), and aluminum - the balance. Preparation procedure: zinc oxide or zinc compound decomposing to give zinc oxide is mixed with aluminum hydroxide or oxide, alkali metal compound, naturally occurring or synthetic silicate or aluminosilicate, or silicic acid, resulting mass extruded, extrudate dried and calcined. Calcination of mass at 550 C results in 30-69% weight loss. Invention can be applied in petrochemical and chemical industries, and petroleum processing. EFFECT: increased chlorine capacity and mechanical strength. 4 cl, 1 tbl, 12 ex
