The present invention relates to an integrated gasification and hydroprocessing process. A hydrocarbonaceous fuel is first gasified to produce syngas, and then a portion of the hydrogen is removed from the syngas. The hydrogen is compressed and used as an excess reactant in a hydroprocessing unit. H ...
