悬浮床加氢裂化集总动力学模型的研究

在不同反应温度、氢初压条件下，通过高压反应釜对克拉玛依常压渣油（KLAR）进行加氢裂化实验，以此模拟悬浮床加氢裂化过程，并根据实验数据及实际工艺中对各种轻油产品收率预测的需求建立了悬浮床加氢裂化六集总（气体、汽油、柴油、蜡油、减压渣油、焦）动力学模型，用matlab软件进行编程，采用最小二乘法对动力学参数进行估算，并进行误差分析。结果表明，建立的六集总动力学模型能很好的对各集总产品收率进行预测，计算结果与实验值基本吻合，大部分误差在5%以内。

STUDY ON LUMPED KINETIC MODEL OF HYDROCRACKING IN SLURRY-BED

Under the conditions of different reaction temperatures and initial hydrogen pressures, the hydrocracking of Karamay atmospheric residue is done in an autoclave in order to simulate the hydrocracking process in slurry-bed. Based on the experimental data and the demand of predicting the yields of light oil products in actual process, a six-lumped kinetic model (gas，gasoline，diesel，gas oil，vacuum residue，coke) of hydrocracking process in slurry-bed is established. The kinetic parameters are determined by the least square method with matlab software and the error is also analyzed. The results show that the model can well predict the yield of each lumped product and the calculation results agree with the experimental value and most of the errors are within 5%.
