However, it has been found that these reactors have the disadvantage that they operate at a pressure of less than 5 bar and that, due to the fact that the reaction of sulfur and hydrogen is mainly catalytic, large amounts of catalyst are required

Embodiment 1

[0102] Embodiment 1 (comparative example)

[0103] 1000 l(STP) / h of hydrogen were introduced continuously via a glass frit at the base into a tube with an inner diameter of 5 cm which had been filled with liquid sulfur up to a height of 1 m. The sulfur consumed is compensated by further metering in liquid sulfur while keeping the filling level constant. Sulfur removed from the product gas stream by condensation is recycled in liquid form into the upper region of the tube. Above the liquid sulfur, sheathed thermocouples for measuring temperature were placed at intervals of 10 cm. When the reactor was electrically heated to 400°C via the outer wall, there was a uniform temperature of about 397°C within the sulfur. However, the thermocouple located above the sulfur showed the highest temperature of 520 °C. In addition, above the liquid sulfur, a sample of the new material made of standard stainless steel (1.4571) was provided at the position of the highest temperature. After ...

Embodiment 2

[0104] Embodiment 2 (comparative example)

[0105] Example 1 was repeated, except that the height of the liquid sulfur was raised to 4m. Maintain the highest temperature value above the liquid sulfur. Severe corrosion phenomena also occurred on material samples.

Embodiment 3

[0106] Embodiment 3 (comparative example)

[0107] Repeat Example 2, except that 15% by weight of powdered Co 3 o 4 MoO 3 / Al 2 o 3 The catalyst is suspended in liquid sulfur. Maintain the highest temperature value above the liquid sulfur. Severe corrosion phenomena also occurred on material samples.

Abstract

The present invention relates to a reactor and process for the synthesis of hydrogen sulfide from elemental sulfur and hydrogen at elevated pressure and elevated temperature. The invention also relates to the use of said reactor for the production of hydrogen sulfide with high yield and low H2Sx content.

Description

technical field [0001] The present invention relates to a reactor and process for the synthesis of hydrogen sulfide from elemental sulfur and hydrogen at elevated pressure and elevated temperature. The present invention also relates to the use of said reactors for high yield and low H 2 S x Content preparation of hydrogen sulfide purposes. Background technique [0002] Hydrogen sulfide is an industrially important intermediate, e.g. for the synthesis of methyl mercaptan, dimethyl sulfide, dimethyl disulfide, sulfonic acid, dimethyl sulfoxide, dimethyl sulfone, and for many sulfur reaction. To date, it has been obtained mainly from mineral oil and natural gas processing and by the reaction of sulfur and hydrogen. [0003] Hydrogen sulfide is usually produced from elemental substances by introducing gaseous hydrogen into a sulfur melt, converting the sulfur into the gas phase and converting the sulfur therein to hydrogen sulfide in an exothermic reaction with hydrogen (Ull...
