Abstract
A method is disclosed for the adsorptive removal of H.sub.2 S from gas mixtures in C-containing adsorption agents with 1-80 bar pressures and regeneration, employing pressure lowering and/or temperature change and simultaneous rinsing with an at most negligibly absorbable component of the gas mixture. A carbon molecular sieve of fossil and/or bituminous fuel is used, with for pore diameter less than 10 nm a pore volume of 15-25 cm.sup.3 /100 g, and micropore volume in pore diameter range 0.35-10 nm less than 10 cm.sup.3 /100 g. The inner surface of the molecular screen can be freed of surface groups capable of reacting with the H.sub.2 S by aftertreatment with reducing gas.
