油页岩气体热载体干馏过程模拟

运用Aspen Plus软件，将油页岩定义为常规物流、非常规物流和常规惰性固体物流的混合物流，结合油母质热解机理、总包一级热解动力学模型，建立了油页岩气体热载体干馏炉模型。在干馏炉正常运行温度下，对油页岩中有机质及其热解产物页岩油、热解气体、半焦等物质的质量进行了计算和分析，并对不同温度下有机质及其热解产物的质量进行了计算和分析。模拟结果与干馏炉设计运行参数符合较好，能方便的对不同温度下热解产物的质量进行预测。

Simulation of dry distillation process of oil shale in heat gas

A model of oil shale retort with gas heat carrier,based on the combination of matter flow of oil shale feedstock and its drying/preheating and pyrolysis process as well as overall first-order pyrolysis kinetics,was developed using Aspen Plus.Components in oil shale feedstock were divided into moisture,organic substance,and minerals,which were defined as conventional stream,non-conventional stream and conventional inertia stream respectively.According to the pyrolysis mechanism of oil shale and the first-order pyrolysis kinetic equation,the amount of organic matter and its pyrolysis products including shale oil,gases and semi-coke was calculated and analyzed at normal operating temperature of the retort and at other different temperatures.The simulation results agreed well with design and operation parameters of the retort,and the model could be used conveniently to predict amount of pyrolysis products at different temperatures.
