ABSTRACT:
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).
