Abstract:
A multi-optimised slurry bed hydrogenation reactor, and a design method therefor and a use thereof. The hydrogenation reactor is provided with an inner circulation structure and a feed distributor, a feed opening being located at a bottom portion of a tower body of the reactor, a discharge opening being located at a top portion of the tower body. The inner circulation structure comprises a circulation bubble cap, a circulation tube and a circulation pump, the circulation bubble cap being located at an inner upper portion of the tower body and being a frustoconical hollow cup, a lower end being connected to the circulation tube which leads to the bottom portion of the tower body of the reactor and is connected to the circulation pump located outside the tower body. The feed distributor comprises an inlet feed distributor and a circulation feed distributor, and is located between a tower body inner wall of an inner lower portion of the tower body and the circulation tube. The feed opening comprises an inlet feed opening and a circulation feed opening. A reaction material passes through the inlet feed opening and the inlet feed distributor to enter the tower body, and circulation material recovered by the inner circulation structure passes through the circulation pump to enter the circulation feed opening, and passes through the circulation feed distributor to enter the tower body. The present invention increases the degree of back-mixing of a reactant, and increases the raw material conversion rate and the light oil yield.
