Abstract

The invention relates to the field of plasma chemistry, and discloses a low temperature plasma reactor and a method for decomposing hydrogen sulfide. The reactor comprises: an inner cylinder (1); an outer cylinder (2) nested in the outer portion of the inner cylinder (1); a center electrode (3) arranged in the inner cylinder (1); a grounding electrode (4) formed by a solid electric-conduction material, wherein the grounding electrode forms at least part of the side wall of the inner cylinder or is arranged around the outer side wall of the inner cylinder; and a barrier medium, wherein the barrier medium forms at least part of the side wall of the inner cylinder or is arranged around the inner side wall of the inner cylinder. According to the present invention, the low temperature plasma reactor can achieve the continuous and stable performing of the hydrogen sulfide decomposition process at a significantly high hydrogen sulfide conversion rate, and can achieve long-cycle operation.

Description

technical field

[0001] The invention relates to the field of plasma chemistry, in particular to a low-temperature plasma reactor 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. Therefore, the decomposition of hydrogen sulfide into sulfur and hydrogen has gradually become a technical field that researchers at home and abroad pay close at...
