Claim:
1. A process for the conversion or hydrotreatment of petroleum or coal-derived liquids comprising: a) feeding one or more liquid hydrocarbon feedstreams and a hydrogen feedstream to a mixing vessel or apparatus wherein said one or more liquid hydrocarbon feedstreams are fully-saturated with hydrogen within said mixing vessel or apparatus and resulting in a mixture that is greater than 90 weight percent liquid phase with the remaining amount undissolved vaporous hydrogen; b) directly processing said mixture that is greater than 90 weight percent liquid phase from said mixing vessel or apparatus in an ebullated-bed reactor for conversion, hydrotreatment, and consumption of hydrogen resulting in a vapor products stream and a liquid products stream; c) routing said vapor products stream for further processing and recovery of liquids and fuel gas; d) routing of a portion of said liquid products stream to an ebullating pump to create an ebullating recycle stream; e) sending a separate portion of said liquid products stream for depressurization and further separation into final liquid and gas products; and wherein said ebullating recycle stream from step d) is one of said hydrocarbon feedstreams from step a).
