    摘要: The recovery of solids, and particularly solid particulates used as catalysts in slurry hydroprocessing, from asphaltene containing hydrocarbons is improved by controlling asphaltene precipitation. The formation of agglomerates of the solid particulates, having an increased diameter, results in the presence of precipitated asphaltenes, possibly due to flocculation. Asphaltene precipitation is controlled by varying process parameters or introducing additional diluent or flush streams that change the polarity of an asphaltene containing liquid product recovered from an effluent of a slurry hydroprocessing reaction zone.
