Abstract: 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.
