Abstract
Heavy hydrocarbon oils are processed by hydrotreatment over a sepiolite supported metal catalyst, described fuller in U.S. Pat. No. 4,152,250, whereby metallic impurities are removed from the oil and its asphaltene content is decreased, and the hydrotreated oil is solvent deasphalted using a propane, butane, pentane, hexane or heptane solvent or mixtures of these to give a deasphalted oil suitable for further treatment, e.g. hydrodesulphurization, and an asphaltic residue.
