Hydrogenation reaction and apparent reaction kinetics were studied under the condition of temperature of 60 ~ 70 ℃, hydrogen pressure of 0.4MPa (absolute pressure) and gas apparent velocity of 2.208 ~ 4.085 cm / s. The results showed that the reaction order of anthraquinone concentration was 0.7 and the apparent activation energy was 38 494 J / mol. The effects of apparent gas velocity on the reaction process and the relationship between gas-liquid mass transfer coefficients and reaction kinetics parameters at different superficial gas velocities were analyzed.
