John G Kunesh: Hydrocracking and hydrotreating shale oil in multiple catalytic reactors. Hydrocarbon Research, Vincent A Mallare, Fred A Wilson, August 17, 1982: US04344840 (41 worldwide citation)

Raw shale oil containing precipitable inorganic compounds such as iron and arsenic are preheated to below the precipitation temperature and then catalytically hydrocracked in an ebullated bed catalytic reactor. The metal compounds are deposited on the catalyst in the reactor, from which they are wit ...
