Abstrakt:	Processes in which hydrogen sulfide admixtures (from a 1% HS + 99% Ar mixture) are removed by sorption on starting carbons and those modified with alkali metal ins of various sizes, made from technical-grade lignin, and hydrogen sulfide is eliminated by catalytic oxidation of HS with oxygen were studied. The factors determining the absorption capacity of the carbons and their catalytic activity in oxidation of hydrogen sulfide were determined: these are, in the first place, presence of water in the pore space and in the hydration shell of modifying ions, size of these ions, and experimental temperature.
