TRANSLATION Amended Text from IPEA Complete Application Text for Transition into the National Phase of the International Patent Application PCT/EP91/01523 A B S T R A C T The process of this invention offers the possibility of desulfurizing gaseous streams under high pressure with comparatively low expenditure in apparatus but at a high recovery rate. For this purpose, H2S is catalytically oxidized directly to sulfur in at least one reactor. With special advantage, two re- actors are used wherein the reactor first in the flow direction, an adiabatically operated reactor without internal cooling, is preferably traversed by the flow from the bottom toward the top, and the reactor that is the second one in the flow direction, a reactor internally cooled with special advantage to a tempera- ture below the sulfur dew point, is traversed by the flow preferably from the top toward the bottom. Usually, differing catalysts are utilized in the two reactors even though also both catalysts consist essentially of TiO2 and selectively oxidize directly H2S, but not H2 and CO. In the first reactor without internal cooling, H2S is selectively oxidized directly by the catalyst under high pressure. The reaction continues in the second, internally cooled reactor, condensed- out sulfur itself acting as a catalyst under the pre- vailing high pressure. Accordingly, there is no need for regeneration of this reactor from liquid sulfur. Product sulfur is condensed out and separated from the high-pressure gas stream. The entire desulfuriza- tion can be still further improved by reduction of the sulfur compounds and/or sulfur vapors to H2S and/or by an adsorption, a chemisorption, or NaOH scrubbing of the H2S, the residual sulfur compounds and/or the sulfur vapor.
