两种工艺条件下渣油加氢产物对比研究 郭靖 兰州交通大学 摘 要 本课题配合渣油加氢处理技术开发工作，针对加工的，即将原料油及加氢处理油正庚烷溶进入色谱柱分离饱和烃、轻芳烃、中芳烃、重芳烃、轻胶质、中胶质、重胶质和沥青质。借助元素分析仪、化学荧光定硫仪、化学发光定氮仪等对原料油、加氢处理油及八组分的氢、碳、硫、氮含量、金属含量等性质进行测定，给出原料油及加氢油组成的详细信息，为 结果表明：硫、氮和金属等杂原子主要集中在较重的组分中。硫主要集中在芳烃和胶质组分中，其中重芳烃和轻胶质中硫的含量最高重芳烃中氮含量较前几个组分明显增多，重胶质氮含量最高。渣油固定床加氢处理是合理利用渣油的最为有效的手段之一。渣油转化为更有价值的产物取决于对其组成和性质的认识，以及原料油与加氢处理油之间的关联关系的研究和转化工艺的选择。：渣油加氢脱除率 Comparative study of the product of residue hydrotreating by two different processes Tong Beizhen （Industry Analysis 0501，Institute of Petrochemical Technology，Liaoning Shihua University，Fushun Liaoning，113001）Abstract Cooperating with FRIPP working on development of residue fixed-bed hydrotreating technologies, various post-processing oils were obtained by two different processes, and the physical and chemical properties of the post-processing oils were investigated to compare the processes. Feedstock and fixed-bed residue hydrotreating product were dissolved by n-heptane, and were further separated into eight components. The eight components were saturates, light aromatics, middle aromatics, heavy aromatics, light resins, middle resins, heavy resins and asphaltene separately. These separation schemes could quantify the components, and prepare for later analyses.With the help of modern instruments, the information of the composition and physical chemistry properties of the samples were provided. Metal content was determined by ICP-AES; Sulfur was detected by ultraviolet fluorimetry, nitrogen by chemiluminescence. Those information and data they offered can provide necessary data for further study on group composition and chemical composition. The results show that heteroatom concentrates in heavier component. Sulfur mainly concentrates in aromatics and resins of eight components. Sulfur content is highest in heavy aromatics and light resins of eight components. Nitrogen content increases in evidence in heavy aromatics, and is highest in heavy resins. The results also demonstrate that at the stage of
