Abstract：Base on the technology of a domestic refinery for FCC diesel liquid-phase hydrogenation in the pipe reactor, a small scale experiment was carried out using RS-2000 as catalyst under the conditions of reaction pressure of 6.5 MPa, reaction temperature of 623.15 K, and initial hydrogen content of 0.42% (mass fraction). A kinetic model for the process was established by the experimental results and model parameters were observed. The simulation results by software MATLAB were in good agreement with the experimental results. The model was also applied to simulate the process of multi-points hydrogen supply under the test reaction conditions. The results indicated that the points of hydrogen supplied and the amount of hydrogen added by each point had a great impact on the reaction results, which could provide references for further study.
