The invention discloses a hydrogenation reactor, and belongs to the field of petrochemical industry. The hydrogenation reactor comprises a first catalyst bed layer and a first gas-liquid distributor, wherein the first gas-liquid distributor comprises a distribution disk, at least a venturi pipe and a hydrogen injection pipe, the distribution disk comprises at least a first through hole, the venturi pipe is positioned below the distribution disk, the venturi pipe and the first through hole form butting fixation in a one-to-one manner, the pipe walls of each venturi pipe are provided with at least a second through hole, each venturi pipe is used for making the hydrogen in a material to be reacted form gas bubbles with a diameter of smaller than a specified threshold through the shearing effect produced during the flowing of the material to be reacted when the material to be reacted flows through a throat pipe position, and the first catalyst bed layer is used for bearing a catalyst so as to make the gas bubble-
