HYDROGEN PRODUCTION IN THE PROCESS OF ELECTROCHEMICAL TREATMENT OF SULFUR-CONTAINING ACID GASES (HYDROGEN SULFIDE OR SULFUR DIOXIDE) SUPPLIED IN SOLUTION WITH AMINE-BASED OR OTHER ORGANIC ABSORBENTS

摘要

A method and an electrochemical cell for hydrogen production by electrochemical decomposition of a sulfur-containing acid gas such as H₂S or SO₂ are disclosed. The method comprises electrolysis of the acid gas in solution in the presence of an absorbent, which may be chemical, physical, or a mixture thereof. In typical embodiments, the absorbent is alkanolamine-based.
