REACTOR AND PROCESS FOR PREPARING HYDROGEN SULPHIDE

摘要

The present invention relates to a reactor and to a process for synthesis of hydrogen sulphide from elemental sulphur and hydrogen at elevated pressure and elevated temperature. The invention further relates to the use of the reactor for preparation of hydrogen sulphide in high yield and with a low H2Sx content.

主权项

1. A reactor comprising:
a lower reactor region suitable for accommodating a sulfur melt, a non-pressure-bearing first cavern and a supply device suitable for controlled supply of pressurized gaseous hydrogen per first cavern, wherein the first cavern is suitable for at least temporary accommodation of a product gas mixture P1 which forms in exothermic reaction and comprises hydrogen sulfide, sulfur and hydrogen, a non-pressure bearing second cavern arranged above the first cavern and suitable for at least temporary accommodation of the product gas mixture P1 formed in the first cavern and for formation of further hydrogen sulfide by exothermic reaction of sulfur and hydrogen to form a product gas mixture P2, and a gas collecting region suitable for accommodating the product gas mixture Pfinal at elevated temperature and elevated pressure relative to standard conditions, wherein at least one of the second caverns has lower heat removal than each of the first caverns (4), and wherein the reactor is suitable for continuous preparation of hydrogen sulfide by exothermic reaction of sulfur and hydrogen to form a final product gas mixture Pfinal comprising hydrogen sulfide and sulfur at elevated temperature and elevated pressure relative to standard conditions.
