The invention discloses a high temperature and high pressure super-gravity hydrogenation reactor and application thereof. The high temperature and high pressure super-gravity hydrogenation reactor comprises a motor, a main shaft, a rotor and a shell, wherein the main shaft at an output end of the motor is penetrated through the bottom of the shell and is inserted into the shell; the rotor is fixed on the upper part of the main shaft; the super-gravity hydrogenation reactor further comprises a rotating disc and a feeding chamber; the rotating disc is fixedly connected with the top end of the main shaft; the feeding chamber is arranged on the upper part of the shell; the lower end of the feeding chamber extends into the shell and is arranged right above the rotating disc; a feeding chamber outlet is formed in the lower end face of the feeding chamber; an ultrasonic probe is arranged in the feeding chamber. The reactor disclosed by the invention can guarantee long-time existence of air bubbles in the liquid phase; the gas-liquid mass transfer efficiency is high; the wetting fraction of a catalyst in the reaction is purposively regulated; the pressure of hydrogen in the reactor can be properly reduced; the device safety can be promoted; the reactor does not need to be serially connected with other large-scale gas-liquid premixing equipment; the equipment investment is reduced.
