Heavy or refractory oils are hydroprocessed in the presence of added water and added hydrogen sulfide with or without a slurry catalyst comprising molybdenum sulfide. The water and hydrogen sulfide may originate from the catalyst preparation procedure.

Heavy oil hydroprocessing

Highly aromatic hydrocarbon feedstocks are converted to jet fuel or diesel fuel using a sulfided, halogen promoted Group VIB - Group VIII metal on an alumina-containing support. The preferred catalyst is a presulfided, fluorine-promoted nickel-tungsten on silica-alumina catalyst wherein the nickel is present in amounts of between 18 and 22 weight percent based on the total catalyst weight.

Production of jet and diesel fuels from highly aromatic oils

A carbonaceous coke is manufactured by the delayed coking of a slurry mixture of from about 10 to about 30 weight percent of caking or non-caking coal and the remainder a petroleum resid blended at below 50.degree. C.
