摘要： The invention relates to a process and to an apparatus for preparing hydrogen sulfide H2S by converting a reactant mixture which comprises gaseous sulfur and hydrogen over a solid catalyst. The reactant mixture is converted at a pressure of from 0.5 to 10 bar absolute, a temperature of from 300 to 450° C. and a sulfur excess in a reactor (1). The sulfur excess corresponds to a ratio of excess sulfur to H2S prepared of from 0.2 to 3 kg of sulfur per kg of H2S prepared.

摘要： The present invention describes a reactor (1) for continuously preparing hydrogen sulfide H2S from hydrogen and sulfur, comprising a distributor device (15) for distributing gaseous hydrogen in a sulfur melt (9) present at least in a lower part of the reactor. The distributor device (15) is arranged in the sulfur melt (9) and comprises a distributor plate (16) which is arranged in the reactor (1) and has an edge (17) extending downward and, if appropriate, has passage orifices (19). The hydrogen from a hydrogen bubble which forms below the distributor plate (16) is (for example through the passage orifices (19)) distributed in the sulfur melt (9) via the distributor plate (16).

摘要： Hydrogen sulfide H2S is prepared from a crude gas stream containing H2S and polysulfanes (H2Sx). The crude gas stream is passed at temperatures of from 114 to 165° C. through catalytically active material present in a vessel, and sulfur is collected in the bottom of the vessel and recycled to the preparation of H2S. This process may be accomplished in an apparatus including a reactor for reacting sulfur and hydrogen, a cooler for receiving and cooling an H2S-containing crude gas stream passed out of the reactor to between 114 to 165° C., a vessel coupled to the cooler, the vessel including catalytically active material and a bottom for collecting sulfur obtained from the crude gas stream, and a line which is connected to the bottom of the vessel and opens into the cooler or into the reactor, for recycling sulfur.
