摘　　要：针对催化裂化(FCC)汽油含硫量较高的缺点,对FCC重汽油进行加氢脱硫工艺条件的优化研究。以脱硫率(X_S)、烯烃加氢转化率(X_H)、选择性因子(α)为考察目标,分别从反应温度、反应压力、氢油比和空速四个方面对工艺条件进行了考察。实验结果表明:FCC汽油重组分进行加氢脱硫具有良好的脱硫率;较优的工艺条件为反应温度为240~250℃,反应压力为1.0~1.5 MPa,氢油体积比为300~350,空速控制为3.0 h^-1。Against the shortcoming of high sulfur content in fluid catalytic cracking（FCC） gasoline, the process conditions optimization of hydrodesulfurization of FCC heavy gasoline is researched. The desulfurization rate（XS）, olefin hydrogenation conversion rate（XH）, selectivity factor（α） are targeted to evaluate the process conditions from the four aspects of reaction temperature, reaction pressure, hydrogen/oil volume ratio, and space velocity. The experimental results show that hydrogenation of heavy components in FCC gasoline can obtain high desulphurization rate, and the optimal process conditions are listed as follows： the reaction temperature is 240 to 250 ℃, the reaction pressure is 1.0 to 1.5 MPa,the volume ratio of hydrogen/oil is 300 to 350, and the space velocity is 3.0 h^-1.
