ABSTRACT:
A liquid hydrocarbonaceous feedstock containing asphaltenes and optionally solids is hydroprocessed by passing the feedstock through a catalytic reaction zone in the presence of a catalyst bed containing a solid hydroprocessing catalyst under hydroprocessing conditions to produce a hydrocarbonaceous effluent containing solids. Plugging of the catalyst bed is avoided by controlling the severity of the hydroprocessing conditions in the catalytic reaction zone to maintain the aliphatic hydrogen concentration of the liquid effluent sufficiently low to prevent substantial precipitation of asphaltenes within the catalytic reaction zone.
