| Zusammenfassung: | A process for the production of hydrogen from a hydrogen sulfide feedstock, comprising a stage for heating feedstock (
1
) in a heating zone (
2, 5
) to a suitable temperature so as to produce a hot gas (
6
) that contains hydrogen and elementary sulfur, whereby this heating is carried out at least in part by an external heat source and a stage for rapid cooling of the hot gas thus obtained, by mixing with a fluid (
8
) by means of at least one mixer (
7
), preferably an ejector, so as to obtain a gaseous effluent (
9
). The mixing time is less than 20 milliseconds. Elementary sulfur (
11
) is separated from this effluent and the hydrogen is recovered.
Application for the elimination of hydrogen sulfide and the production of hydrogen. |
