Re-refining lubricating oil in a bed of oil shale

Patent ·
OSTI ID:6598461

A method of reclaiming usable stock from used lubricating oil includes passing the used oil through a bed of oil shale containing kerogen. The shale removes impurities from the oil. The shale is then heated to convert the kerogens to shale oil in the presence of hydrogen donor compounds contained in the lubricating oil remaining in the shale. These enhance hydrogen transfer during shale oil production.
