发明名称	PROCESS FOR REMOVAL OF SULFUR AND ASH FROM COAL
摘要	<p>PROCESS FOR REMOVAL OF SULFUR AND ASH FROM COAL A process for reducing the sulfur and ash content of coal wherein coal particles are treated in an aqueous slurry with a minor amount of hydrocarbon oil to form coal-oil aggregates. The coal-oil aggregates are separated from ash and mineral matter in the slurry by dissolved gas flotation. Optionally, the coal particles may be treated with a conditioning agent prior to the aggregation step. Recovered coal particles comprise a substantial part of the feed carbon values.</p>
