    摘要: A process for reducing the sulfur and ash content of coal wherein coal particles are treated with a conditioning agent in an aqueous slurry prior to agglomeration with a minor amount of hydrocarbon oil. After separation of the coal-oil agglomerate from ash and mineral matter remaining in the aqueous slurry, additional oil is added to provide a slurry of coal particles in hydrocarbon oil. Agglomeration of remaining ash and mineral matter is effected by addition of a minor amount of water. After separation of the mineral agglomerate and recovery from the oil slurry, treated coal particles are substantially reduced in ash and sulfur content.

    摘要: A process for the removal of metal poisons such as nickel, iron and/or vanadium from a hydrocarbon conversion catalyst which includes the step of contacting the catalyst with a sulfur-containing compound to convert at least a portion of the metals on the catalyst to a sulfur-containing metal compound. The weight % sulfur on the thus treated catalyst is controlled to about 40-90%, preferably about 40-75%, of the weight % of the total nickel, vanadium and iron on the catalyst. Preferably, the sulfur-containing compound is hydrogen sulfide in admixture with a reducing gas such as hydrogen and/or carbon monoxide. This step facilitates metal removal in subsequent processing steps.
