Experimental Study on the Absorption Conditions of Indirect Electrolysis of Hydrogen Sulfide for Hydrogen and Sulfur

摘要

The acid gas containing hydrogen sulfide is unavoidable production from gas plants and refineries.The technology of industrial treatment of hydrogen sulfide mostly includes the Claus process and the wet absorption process which have some disadvantages such as costly equipment,high temperature and rigorous ratio of H_2S to SO_2.These processes recover sulfur,but the hydrogen is oxidized to water and unrecoverable.In recent years,the technologies which can recovery of hydrogen and sulfur from hydrogen sulfide have been paid more attention.Electrolysis of hydrogen sulfide is promising way to generate hydrogen and sulfur from H_2S and can been carried out by the different routes.
