Abstract
Methods of hydroprocessing hydrocarbon streams are provided that employ substantially liquid-phase hydroprocessing conditions. In one aspect, the method includes directing a hydrocarbonaceous feed stock to a first substantially liquid-phase hydroprocessing zone wherein an effluent from the first substantially liquid-phase hydroprocessing zone is directed to a second substantially liquid-phase hydroprocessing zone generally undiluted with other hydrocarbon streams. In another aspect, the method recycles a liquid portion of a liquid hydrocarbonaceous effluent from the second substantially liquid-phase hydroprocessing zone, which preferably includes an amount of hydrogen dissolved therein, to the hydrocarbonaceous feed stock so that the feed to the first substantially liquid-phase hydroprocessing zone has a relatively larger concentration of dissolved hydrogen relative to the hydrocarbonaceous feed stock.
