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 hydrocracking process is carried out in the presence of a catalyst consisting of finely divided coal or other carbonaceous material carrying catalytically active metals from Group VIA and Group VIII of the Periodic Table of Elements, e.g. cobalt and molybdenum. The catalyst is slurried with the charge stock and has been found to greatly reduce coke precursors and thereby prevent the formation of carbonaceous deposits in the reaction zone while also being effective in reducing the sulfur concentration of the product.
