摘　　要：C_(10)芳烃是1种重要的化工原料,作者讨论C_(10)芳烃的直接和间接利用途径,着重描述其中的均四甲苯、石油萘、甲基萘、三苯等产品的用途。简单介绍C_(10)芳烃深加工工艺以及国外重芳烃轻质化技术,Toray TAC9、ZEOLYST/SK、Trans-Plus等有代表性的国外重芳烃轻质化反应工艺具有各自的优势与不足,未来重芳烃轻质化工艺技术发展应针对重芳烃轻质化反应的特点,开发以小颗粒、大孔径的分子筛作催化剂活性组元,增产附加值高的二甲苯。主要技术方案和工艺流程对C_(10)芳烃开发利用的展望,对提高C_(10)芳烃的整体效益以及深加工的研究具有十分重要的意义。C10 aromatics hydrocarbon was an important chemical raw material, the direct use and indirect use of C10 aromatics hydrocarban were discussed, and the products including 1,2,4,5-teramethybenzene, petronaphthalene, methyl-naphthalene, benzene, toluene and xylene, etc. were explained in detailed. The process of producing C10 aromatics hydrocarbon unit and the advanced technology of the conversion of heavy aromatics to Light aromatics abroad were described. The advantages and shortcomings of some representative technologies of the conversion of heavy aromatics to light aromatics, such as Toray TAC9, ZEOLYST/SK and Trans-Plus, were analyzed. The key future trends in this field were presented. According to the characteristics of the conversion reaction, the molecular sieves with small particle size and large pore diameter should be chosen as an active ingredient of solid acid catalysts to produce xylerte. And the technical proposal and process flow, etc. also were discussed. The future exploitation and coprehensive utilization of C10 aromatics hydrocarbon were also presented on the basis of the literature reviewing. Improving the overall efficiency and the deep processing of raw materials of C10 aromatics hydrocarbon were of great significance.
