SORBENT-CATALYST PREPARATION METHOD Russian patent published in 2004 - IPC

Abstract RU 2236902 C1

FIELD: sorbents.

SUBSTANCE: objective of invention is treatment of industrial gases and use in individual gas masks. Preparation procedure comprises providing impregnation triethylenediamine solution (concentration 0.9-1.3 wt %) and impregnating metal-containing activated carbon granules, ageing the latter and heat treatment at 110-150^оС at temperature raise rate 1-4^оС/min, impregnation solution volume constituting 0.8-0.9 summary pore volume in substrate.

EFFECT: substantially increased protective capacity with respect to chlorocyane in thin layer at high relative humidity.
