ABSTRACT:
Sulfur compounds contained in fuel gases produced from the gasification of coal or petroleum residua area removed at about 1600.degree. F temperature by contacting the gas with an absorbent material comprising a strong, macroporous particulate solid support containing molten metal carbonate, such as potassium carbonate, within its pores. Following such contacting and reaction of the sulfur compounds in the hot gas with the supported metal carbonate absorbent, it is regenerated by being contacted at high temperatures with steam and CO.sub.2 to remove the sulfur, which is recovered as H.sub.2 S. The metal carbonate absorbent material is reused by again contacting it with the hot fuel gas for sulfur removal, after which the sulfur-free fuel gas is burned in a combustion process such as a gas turbine to produce power.
