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 suitable for continuous preparation of hydrogen sulphide by exothermic reaction of sulphur and hydrogen to form a final product gas mixture Pfinal comprising hydrogen sulphide and sulphur at an elevated temperature and an elevated pressure relative to standard conditions, said reactor comprising
a lower reactor region suitable for accommodating a sulphur melt, a non-pressure-bearing first cavern and a supply device suitable for controlled supply of pressurized gaseous hydrogen per first cavern, said cavern being suitable for at least temporary accommodation of a product gas mixture P1 which forms in exothermic reaction and comprises hydrogen sulphide, sulphur and hydrogen, a non-pressure bearing second cavern which is arranged above the first cavern and is suitable for at least temporary accommodation of the product gas mixture P1 formed in the first cavern and for formation of further hydrogen sulphide by exothermic reaction of sulphur and hydrogen to form a product gas mixture P2, and a gas collecting region suitable for accommodating the product gas mixture Pfinal at an elevated temperature and an elevated pressure relative to standard conditions, wherein the second cavern comprises a supply device suitable for controlled supply of pressurized gaseous hydrogen.
