In this paper, the research progress of the fixed bed catalyst and fluidized bed catalyst and their advantages and disadvantages are introduced. The influences of the factors during Ni-based catalyst and Pd-based catalyst preparation process on their catalytic performance are introduced. Researches on the catalysts with high catalytic activity and selectivity for the hydrogenation reaction are reviewed. The characteristics and research progress of hydrogenation reactors are also introduced and compared. Based on the detailed comparisons between the fluidized bed and fixed bed, it is concluded that the production with fluidized bed has many advantages of relative lower cost, less anthraquinone degradation, high catalyst utilization rate and high hydrogenation efficiency. From an application perspective, the differences between fluidized bed and fixed bed are introduced. The paper finally points out that the production with fluidized bed has become the developing tendency of the anthraquinone route and will replace the process with fixed bed. The practical research difficulties, developing trend and some suggestions for the development of the anthraquinone route are presented.
