Desulfurization process utilizing an oxidizing agent, carbonyl compound, and hydroxide

摘要

Sulfur-containing carbonaceous materials are desulfurized by reaction with a mixture of an oxidizing agent and a carbonyl compound under alkaline conditions at a temperature ranging from ambient temperature to about 250 DEG F. and a pressure of about 1 atmosphere to 2 atmospheres. The products of the reaction are a desulfurized carbonaceous material in which the sulfur content is less than about 1%, and gaseous sulfur compounds. The carbonyl compound can be recovered and reused.
