Abstract
Method for converting a heavy or high boiling fraction oil to separate upgraded products, namely synthetic natural gas and carbon-coated aluminum, by hydrocracking the residual oil in the presence of particulate alumina at elevated temperature and pressure. The product streams, carbon-impregnated alumina and hydrocracked gaseous products, upon purification, are each of separate value. Economics of the process are improved by integration of certain purification steps and by the provision of hydrogen, for the hydrocracking process, by recycle from separated hydrogen in the synthetic natural gas stream and from partial oxidation of an additional portion of residual oil feedstock and separated heavy aromatics from the hydrocracking unit.
