Process for converting heavy hydrocarbon into more valuable product

摘要

A process for converting a heavy hydrocarbon into a more valuable product which comprises: adding to the heavy hydrocarbon at least two kinds of substances comprising an oil-soluble or water-soluble transition metal compound and an ultra-fine powder which can be suspended in a hydrocarbon and has an average particle size within the range from 5 to 1000 m mu ; thermally cracking the heavy hydrocarbon in the presence of a hydrogen gas or a hydrogen sulfide-containing hydrogen gas; and recovering the resulting lighter hydrocarbon oil.
