针对国内某石化公司提出的催化柴油管式液相加氢新工艺,在压力为6.5 MPa,温度为623.15 K,进口混氢量为0.42%(质量分数)的条件下,以RS-2000为催化剂进行了初步小试实验研究。根据实验结果建立了催化柴油管式液相加氢反应动力学模型,主要包括脱硫(HDS)、脱氮(HDN)和芳烃加氢饱和反应的动力学模型以及氢耗方程。用 MATLAB 软件求解模型参数并将模型计算结果与实验值进行比较,两者吻合良好。最后用所建模型预测了该实验条件下的多点补氢过程,结果表明,补氢点数以及每点补氢量的多少对反应结果都有很大影响,可为新工艺的进一步研究提供参考。

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.
