| 摘 要： | 随着国内重芳烃产量逐年提升，炼厂对提质增效需求日益高涨，对重芳烃高效转化利用技术的需求也日益迫切。由于重芳烃富含稠环芳烃，而加氢是稠环芳烃转化为单环芳烃的重要手段，因此，重芳烃中代表性芳烃的加氢机理和热力学研究日趋受到重视。本文从重芳烃原料性质分析入手，详细阐述了重芳烃中代表性芳烃的加氢反应路径及机理、加氢反应热力学的研究进展，以期为实际应用和催化剂开发提供参考。稠环芳烃组成对适宜的加氢反应条件、单环芳烃产品收率、氢耗、反应放热等都有较大影响，为了最大化生产低碳芳烃、降低氢耗，需要根据重芳烃的组成，从原料预切割/预处理、催化剂结构及活性中心、工艺条件这3个方面同时着手进行优化，进而实现对加氢过程的定向调控。

| Abstract: | With the increasing yield of heavy aromatics, the refinery’s demand for quality and efficiency enhancement in production is growing significantly. Meanwhile, the need for effective conversion and utilization of heavy aromatics is becoming more and more urgent. Since heavy aromatic hydrocarbons are rich in polycyclic aromatic hydrocarbons(PAHs), and hydrogenation is an important means of converting PAHs into monocyclic aromatic hydrocarbons, the studies on the hydrogenation mechanism and thermodynamics of typical aromatics in heavy aromatics have attracted increasing attention. Starting by analyzing the properties of heavy aromatic hydrocarbons, we described the research progress in the hydrogenation reaction path and the mechanism of typical aromatics in detail, as well as the hydrogenation reaction thermodynamics, which could provide reference for their practical application and the catalyst development. We also pointed out that the composition of PAHs has a great influence on the suitable hydrogenation conditions, the yield of monocyclic aromatics, hydrogen consumption, and reaction heat release. In order to maximize the production of light aromatics and to reduce hydrogen consumption, optimization should be carried out by considering raw material precutting/pretreatment, catalyst structure and activity center, and process conditions together according to the composition of heavy aromatic hydrocarbons, so as to realize directional regulation of hydrogenation process. |
