SORBENT CATALYST PREPARATION METHOD Russian patent published in 2006 - IPC B01J20/20 C01B31/08

Abstract RU 2288032 C1

FIELD: sorbents.

SUBSTANCE: invention relates to preparation of gas-treatment sorbents and provides a method for preparing impregnating solution, impregnation with prepared solution of active carbon having copper/chromium/silver complex deposited thereon, ageing and heat treatment of granules. Impregnating solution containing 18-30 g/dm³ sodium hydroxide and 30-45 g/dm³ ammonium carbonate is prepared at 40-60°C. Before impregnation, solution is cooled to temperature not superior to 30°C and impregnation is conducted with volume of impregnating solution constituting 0.91-0.94 volume of pores of initial active carbon with copper/chromium/silver complex deposited thereon.

EFFECT: increased dynamic activity of sorbent with regard to hydrogen sulfide.
