Description

technical field

[0001] The invention relates to the field of plasma chemistry, in particular to a high-flux low-temperature plasma discharge device and a method for decomposing hydrogen sulfide. Background technique

[0002] hydrogen sulfide (H 2 S) is a highly toxic and foul-smelling acid gas, which not only causes corrosion of metals and other materials, but also harms human health and pollutes the environment. At present, my country's large and medium-sized oil refineries use the traditional Claus method to treat H-containing 2 S tail gas, and recover sulfur. The method recovers only the sulfur in the hydrogen sulfide, but converts the precious hydrogen into water. From the perspective of comprehensive utilization of resources, in the traditional hydrogen sulfide recovery process, hydrogen resources have not been effectively utilized.

[0003] Therefore, the decomposition of hydrogen sulfide into sulfur and hydrogen has gradually become a technical field that domestic...
