Abstract:
A method for treating an aqueous slurry of hydrocarbonaceous ore containing hydrocarbon compounds and substrate solids to recover hydrocarbon residues therefrom, comprising the steps of:a) conditioning said slurry by heating to mobilize a first portion of said hydrocarbon residues;b) adding an amount of an oxidant to said slurry;c) releasing a second portion of said hydrocarbon residues from said substrate solids contained in said slurry in response to said oxidant;d) partially oxidizing at least part of at least one of said first and second hydrocarbon residue portions to yield partially oxidized hydrocarbon residues, said amount of oxidant being predetermined to be insufficient to completely oxidize said hydrocarbon residue portions; ande) separating a liquid effluent containing said partially oxidized hydrocarbon residues from said substrate solids.
