Abstract: A process for reducing the pyritic sulfur content of coal comprising the steps of:(1) contacting an aqueous slurry of water and pyrite-containing coal particles at elevated temperature with oxygen, the contacting of step 1 being such that without step 2 the aqueous slurry would have a pH of less than 5.5;(2) maintaining the aqueous slurry of step 1 at a pH of from about 5.5 to 12.0; and(3) recovering coal particles of reduced pyritic sulfur content.

Abstract: A process for the removal of metal poisons such as nickel, iron and/or vanadium from a hydrocarbon conversion catalyst which includes the steps of contacting the catalyst with both a reductive wash and a subsequent oxidative wash to remove at least a portion of the metal poisons from the catalyst. A preferred oxidative wash medium comprises an aqueous solution of hydrogen peroxide. The vanadium and nickel metals may be recovered from the resultant used wash solutions for possible metallurgical use.

Abstract: A process for reducing the sulfur content of coal comprising the steps of: 1. contacting coal particles with an aqueous solution of iron complexing agent, and an oxidant to preferentially oxidize at least a portion of the sulfur in the coal; 2. thermally treating the oxidized sulfur-containing coal at elevated temperature to reduce the sulfur content of the coal; and 3. recovering coal particles of reduced sulfur content.
