Abstract

A method of removing gaseous organic sulfide contaminants from gaseous mixtures is provided where the method includes dissolving the organic sulfide contaminants in a solution of an acid-based catalyst to permit cleavage of the sulfur atom from the organic sulfide molecule, such that the cleaved sulfur atom can be further reduced electrochemically to elemental sulfur or alkali metal polysulfides.

Claims (2)

1. A method of removing gaseous organic sulfide contaminants from gaseous mixtures, the method comprising dissolving the organic sulfide contaminants in a solution comprising an acid-based catalyst to permit cleavage of the sulfur atom from the organic sulfide molecule, such that the cleaved sulfur atom can be further reduced electrochemically to elemental sulfur or alkali metal polysulfides, wherein the solution further comprises one of the following: a hydrophilic glyme, a hydrophobic glyme, and polyglycols.

2. The method of Claim 1 , wherein the acid-based catalyst comprises polystyrene sulfonates or polystiyene phosphonates.
