Abstract
An improved process is described for the hydrocracking of heavy hydrocarbon oil, such as oils extracted from tar sands. The charge oil in the presence of an excess of hydrogen is passed through a tubular hydrocracking zone, and the effluent emerging from the top of the zone is separated into a gaseous stream containing a wide boiling range material and a liquid stream containing heavy hydrocarbons. According to the novel feature, the charge oil is in the form of a slurry together with an iron-coal catalyst. The presence of this catalyst in the charge oil serves to greatly reduce coke precursors, such as benzene and pentane insolubles, and thereby prevent the formation of carbonaceous deposits in the reaction zone.
