摘　　要：利用CoMoP/Al2O3-TiO2汽油加氢脱硫工业催化剂,在催化精馏加氢脱硫装置上对FCC汽油重馏分进行了加氢脱硫性能研究。在压力2.0 MPa、反应段平均温度264℃、氢油比300∶1、空速2.0 h-1、回流比2的条件下,重馏分脱硫率达到98.50%,总硫质量分数由850.42μg/g降低到12.72μg/g,辛烷值损失仅为0.9个单位。对新型垂直筛板塔与普通填料塔、固定床进行了加氢脱硫性能对比分析,结果表明新型垂直筛板塔的加氢脱硫性能明显优于普通填料塔和固定床。By using CoMoP/Al2O3-TiO2,a commercial gasoline hydrodesulfurization catalyst,the hydrodesulfurization of FCC gasoline heavy cut in catalystic distillation hydrodesulfurization plant is studied.The desulfuration rate of FCC gasoline heavy distillate can reach 98.50% and the total sulfur can drop to 12.72 μg/g from 850.42 μg/g under 2.0 MPa of the operating conditions of pressure,264℃ of reactive bed average temperature,300∶1 of hydrogen/oil volume ratio,2.0 h-1 of LHSV and 2.0 of reflux ratio,and its octane...
