Document Type and Number:
Japanese Patent JP2002502909
Kind Code:
A
Abstract:
A method and reactor for catalytic hydroprocessing liquid hydrocarbon feedstock at elevated temperatures and pressures for producing a liquid hydrocarbon product involves introducing the feedstock into a reactor having upper and lower reaction zones, each reaction zone having a hydroprocessing catalyst bed therein, the feedstock being introduced at the top of the lower reaction zone for downward flow through and reaction within the catalyst bed therein; collecting a partially reacted liquid effluent from the lower reaction zone; pumping the partially reacted liquid effluent to and introducing it at the top of the upper reaction zone for downward flow through and reaction within the catalyst bed therein; introducing hydrogen gas at the top of the upper reaction zone for flow downwardly and sequentially through and over the catalyst beds in the upper and lower reaction zones in co-current contact with the liquid in the reaction zones, the hydrogen reacting with the liquid in the reaction zones whereby the liquid effluent from the upper reaction zone comprises a liquid hydrocarbon product; and collecting and recovering the liquid hydrocarbon effluent product from the upper reaction zone.
