Coal-anthracene oil slurry liquefied with carbon monoxide and barium-promoted catalysts

Abstract

A heavy hydrocarbon feedstock is upgraded by at least one of the processes of desulfurization, decreasing carbon residues, increasing API gravity, and liquefaction of solid feedstock by reacting the feedstock at elevated temperature and pressure in the presence of carbon monoxide and in the presence of a catalytically active metal. In one embodiment the active metallic catalyst is associated with minor amounts of alkali or alkaline earth metals to minimize promotion of cracking side reactions. In a preferred embodiment a heavy hydrocarbon feedstock is upgraded in the presence of the catalyst system formed from a barium salt which has been deposited on cobalt molybdate dispersed on an alumina support.
