以催化裂化油浆为原料，在高压釜中进行悬浮床加氢裂化实验模拟，考察了反应温度、催化剂浓度和初始氢气压力对反应效果的影响。在单因素实验考察的基础上，采用响应曲面法研究反应条件对石脑油和柴油总收率的影响，拟合回归方程并求解得到最优反应条件。结果表明，优化的催化裂化油浆悬浮床加氢裂化反应条件为：反应温度447.7℃、催化剂浓度146.38 μg/g、初始氢气压力9.63 MPa。在此条件下回归方程和验证实验得到的石脑油和柴油总收率分别为42.53%和42.87%。

The simulation hydrocracking experiment of FCC slurry is conducted in a magnetic-stirred autoclave to simulate the situation in real slurry-bed and the influences of reaction temperature,catalyst concentration and initial hydrogen pressure are investigated.Based on single factor experiments,the influence of reaction conditions on the total yield of naphtha and diesel is studied by response surface methodology.The optimal reaction conditions are obtained by fitting regression equation.The optimal reaction conditions for hydrocracking FCC slurry in a slurry bed are as follows:reaction temperature is at 447.7℃,catalyst concentration is 146.38 μg·g^-1 and the initial pressure of hydrogen is 9.63 MPa.The total yield of naphtha and diesel oil is 42.53% by regression equation and 42.87% by verification experiment under these optimal conditions.
