ABSTRACT:
A carbonaceous material is subjected to a hydrotreating process in which it is desulfurized, deasphalted and demetallized by reaction with hydrogen in a molten medium in the presence of potassium hydroxide and water. The water is present in an amount sufficient to minimize the formation of gaseous hydrocarbonaceous products but insufficient to significantly reduce the effectiveness of potassium hydroxide as the hydrotreating agent. The process is characterized by producing a very small amount of gaseous hydrocarbonaceous products, desulfurizing the carbonaceous feed to the extent of at least about 80%, deasphalting the feed to the extent of at least about 60%, and demetallizing the feed to the extent of at least about 90%. In a preferred embodiment, spent potassium hydroxide is regenerated and recycled to the molten medium.
