Hydrogen sulfide decomposition into hydrogen and sulfur by quinone cycles. Final report, Part 1, June 1989-August 1992
The HYSULF process decomposes hydrogen sulfide using mild conditions. In the process, hydrogen sulfide is first reacted with a quinone in an organic solvent to produce sulfur and hydroquinone. After sulfur removal, hydroquinone is catalytically processed to recover hydrogen and recycle quinone-solvent. The produced sulfur is of excellent quality and easily recoverable from the solvent. The organic solvent should eliminate corrosion problems associated with commercial aqueous redox systems which produce only sulfur. Since no air oxidation is used, the sulfite-sulfate salt problems of aqueous systems will be avoided. The purpose of the GRI contract was to develop a better mechanistic understanding of process chemical reactions and economics. This was to result in (1) Increased quinone conversion and sulfur precipitation rates; (2) Determining the effect of carbon dioxide on first stage chemistry; (3) Eliminating the anthrone by-product produced in the dehydrogenation step. Essentially, all of the objectives of the project were completed.
