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, 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, 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, a non-pressure-bearing installed a suitable for continuous transfer of the total amount of product gas mixture Pu formed in the lower reactor region to the gas collecting region, wherein said installed device comprises heterogeneous catalyst for further conversion of hydrogen and sulphur present in the product gas Pu to hydrogen sulphide.
