摘　　要：运用Aspen Plus软件建立了以页岩灰为热载体的油页岩干馏模型。利用该模型对柳树河油页岩的固体热载体干馏过程进行了模拟,并与试验数据进行了对比,发现模拟结果与试验结果基本相符。在此基础上,分析了干馏终温和停留时间对热解水、热解气体和页岩油产量的影响。计算结果表明,柳树河油页岩的干馏最佳温度在520℃左右,干馏产物收率随干馏终温的升高而升高。热解温度过低时,油页岩中的有机质分解不充分,干馏产物收率随着停留时间的延长而增加。在较高的干馏终温下,油页岩中的有机质分解迅速、充分,停留时间对干馏产物收率没有明显的影响,所以提高干馏终温比增加停留时间更有效。A model for retorting process of oil shale using shale ash as heat-carrier has been developed using Aspen Plus process simulator. The simulation results agree with the experimental results for process simulation of Liushuhe oil shale retorting. The effect of retorting temperature and residence time on the yield of pyrolysis water, pyrolysis gases and shale oil is discussed by the developed model in this paper. The computational results indicate that the optimal retorting temperature of Liushuhe oil shale is about 520℃. The organic matter of oil shale can not decompose completely and the pyrolysis products yield increases with the residence time at low temperature. At high temperature, the organic matter of oil shale decomposes quickly and completely. So the effect of residence time on pyrolysis products is not obvious. Increasing the pyrolysis temperature is more effective than increasing the residence time.
