双金属Pd/Al2O3催化剂液相选择性加氢工艺研究

通过双金属Pd/Al2O3催化剂在裂解汽油选择性加氢过程中的工艺性能研究，讨论了该催化剂在液相选择性加氢过程中原料油性质、反应器入口温度以及液相总空速等在反应中的影响，得出了该催化剂基本的优化工艺条件，同时对该催化剂在反应中的双烯加氢率和绝热温升数学模型进行探讨，得到的结果与实验能很好地吻合。

STUDY ON THE LIQUID-PHASE SELECTIVE HYDROGENATION OVER BIMETALLIC Pd-M/Al2O3 CATALYST

The catalytic performance of bimetallic Pd-M/Al2O3 catalyst in selective hydrogenation of pyrolysis gasoline was investigated and the effect of feed properties, reactor inlet temperature and total liquid space velocity was discussed. The optimum process conditions were obtained, i.e. a feed diene number of about 10 gI/100g, a reactor inlet temperature of 45℃ and a total liquid space velocity of 22 h-1. Furthermore, mathematic models related with the hydrogenation rate of conjugated diene and adiabatic temperature rise were discussed, and the calculated results were in good agreement with the experimental data.
