Description

technical field

[0001] The invention relates to the field of plasma chemistry, in particular to a high-throughput 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 endangers human health and pollutes the environment. At present, large and medium-sized refineries in my country adopt the traditional Claus method (Claus) to treat 2 S tail gas, and recover sulfur. The method recovers only the sulfur in hydrogen sulfide, but converts the valuable hydrogen into water. From the perspective of comprehensive utilization of resources, hydrogen resources have not been effectively utilized in the traditional hydrogen sulfide recovery process.

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