Abstract
The invention relates to a process for the removal of hydrogen sulfide from gases by passing the gases in the presence of oxygen and steam over a catalytic absorption mass which contains inert porous support materials as support and catalytically active metal sulfides and/or metal oxides for the selective oxidation of hydrogen sulfide to elemental sulfur, the sulfur formed being simultaneously deposited on the absorption mass, and regenerating the charged catalytic absorption mass.
