A method is disclosed for the adsorptive removal of H2S 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 cm3/100 g, and micropore volume in pore diameter range 0.35-10 nm less than 10 cm3/100 g. The inner surface of the molecular screen can be freed of surface groups capable of reacting with the H2S by aftertreatment with reducing gas.

Method for the adsorptive removal of hydrogen sulfide from gas mixtures in carbon containing absorption agents by adsorption at pressures between 1-80 bar and regeneration, by pressure lowering and/or temperature change while simultaneously rinsing with a nonadsorbable or only negligibly adsorbable

Method for the adsorptive removal of hydrogen sulfide from gas mixtures in carbon containing absorption agents by adsorption at pressures between 1-80 bar and regeneration, by pressure lowering and/or temperature change while simultaneously rinsing with a nonadsorbable or only negligibly adsorbable component of the gas mixture in an adsorption reactor, characterized in that a molecular carbon containing screen is used, made of fossil and/or critical bituminous fuel with at pore diameter smaller than 10 nm measured by methanol adsorption pore volume of 15-25 cm3/100 g and micropore volume in the pore diameter range of 0.35-10 nm is smaller than 10 cm3/100 g, wherein an inner surface of said molecular screen is relieved from surface groups which are capable of reacting with the H2S by means of an aftertreatment with a reducing gas.
