ABSTRACT:
A process of concurrently dedusting and upgrading particulate laden raw, whole retort oil is provided which comprises the steps of: retorting solid hydrocarbon-containing material such as oil shale to liberate an effluent stream of dust laden hydrocarbons; injecting the dust-laden retort effluent product stream into a catalytic hydrotreater; agitating the product stream in the hydrotreater to constantly maintain the particulates in suspension within the oil; catalytically hydrotreating the agitated product stream in the presence of a hydroprocessing gas at a pressure of from 500 to 3000 psi, a temperature of from 650.degree. to 850.degree. F. and a space velocity of from 0.1 to 6.0 hr.sup.-1, whereby the suspended particulates are agglomerated to facilitate solid-liquid separation and substantial amounts of sulfur and nitrogen contaminants are simultaneously removed from the resulting ungraded oil; and mechanically separating the agglomerated particulates from the upgraded whole oil. The product oil may be further upgraded either by treatment with aqueous sulfuric acid or by hydrotreatment.
