Abstract

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.
