为了尽快实现超临界汽油中低温煤焦油加氢裂解工艺的工业化，利用ASPEN PLUS 模拟煤焦油在超临界溶剂中的加氢过程，以获得整个工艺运行的基本参数。本文基于超临界汽油中低温煤焦油加氢裂解的中试试验数据，对超临界汽油中低温煤焦油加氢裂解工艺进行模拟。首先，煤焦油代表组份选自煤焦油中含量较高的组分，汽油溶剂在模拟中根据其沸点曲线定义为虚拟组分；其次，根据碳离子反应机理，所有的煤焦油代表组分发生裂解反应，并将所有反应输入模型；加氢裂解过程主要选用 RK-SOAVE 和BK10物性方法，超临界汽油在模拟过程中定义为亨利组分；最后，根据煤焦油加氢裂解的反应特征，模型中主要包含3个基本模块，即RYIELD、Separtor和PetroFrac，分别模拟加氢裂解、气液分离和常压分馏。模拟时将超临界汽油中低温煤焦油加氢裂解中试实验条件数据输入模型，模拟结果表明：模型预测值与实验值基本一致，表明该模型能较好的反映超临界汽油中低温煤焦油加氢裂解工艺过程。并利用模型对年处理15万吨的超临界汽油中煤焦油加氢裂解工艺进行优化设计，获得了工艺的基本参数和能耗，为超临界汽油中低温煤焦油加氢裂解工艺工业化提供了理论依据和设计参考。

In order to realize the pilot test of low temperature coal tar hydrocracking process in supercritical gasoline, hydrocracking process should be simulated to obtain the fundamental information of the whole process using the ASPEN PLUS simulator. Based on the bench test of low temperature coal tar hydrocracking process in supercritical gasoline, the modeling of the low temperature coal tar hydrocracking process was developed. Firstly, some model components with higher contents were selected to express the coal tar, and gasoline solvent was defined as a pseudo component for the modeling input according to its true boiling point curve;Secondly, all the modeling components were cracked in the simulation on the basis of carbenium ions reaction mechanism, the reactions were input into software; then the RK-SOAVE and BK10 property methods were used in the modeling of hydrocracking process, and supercritical gasoline was defined as HENRY component in the present simulation;at last, according to

煤焦油通过溶剂分析可定量分离为三部分：甲苯不溶物、沥青质和油相。本文主要研究了煤焦油在此分离过程中芳烃溶剂类型、萃取方法、甲苯溶液浓缩量、烷烃溶剂类型和正庚烷溶剂与甲苯溶液浓缩量的添加比例对煤焦油沥青质沉淀量的影响。结果表明，甲苯溶液浓缩量、正庚烷与甲苯溶液浓缩量的添加比例对沥青质沉淀量的影响较大，萃取方法次之，将苯替换成甲苯影响最小。当选择甲苯溶解煤焦油，超声萃取3h，甲苯溶液浓缩量9mL，正庚烷与甲苯溶液浓缩液的添加比例为20∶1时，煤焦油沥青质的沉淀量为13.4%。本实验表明煤焦油的分离工艺会影响沥青质沉淀量，故在研究煤焦油沥青质性质和结构时需注明沥青质的沉淀分离条件。

Solvent analysis is a method for quantitative separation of coal tar into toluene insoluble, asphaltene (toluene soluble,pentane insoluble),and oil (pentane soluble). The prime objective was to identify the variables in the procedure,including aromatic solvent type,extraction method,amount of toluene solution concentrate (degree of toluene boil-off) ,alkane solvent type,and ratio of n-heptane to toluene solution concentrate that affected the precipitate obtained for asphaltene content. Substitution of toluene with benzene and extraction method did not have a large effect on the precipitate reported for asphaltene. Heptane was chosen as alkane solvent instead of pentane. However amount of toluene solution concentrate and ratio of n-heptane to toluene solution concentrate did have a large effect on the precipitate reported as asphaltene. Coal tar from northern Shaanxi province was tested. With the suitable time of ultrasonic extraction for 3 hours,toluene solution concentrate o
