Final Report | Removal of Sulfur From Gasified Coal at or
The method for sulfur removal is based on using sulfide ion conducting metal sulfides. At high temperatures, and under a sulfur partial pressure gradient, the sulfur contained in the gasified coal stream is selectively removed. Using a sulfide ion conducting separation membrane enables true hot gas cleanup of sulfur from gasified coal.
