Abstract

Abstract: In the process of coal and petroleum processing, aromatics are important precursors or intermediate products.The preparation of advanced carbon materials, such as needle coke and carbon fiber, by heat treatment of coke tar or petroleum is mainly about pyrolysis of aromatics, including complex condensation and cracking reactions.In this paper, the study on the mechanism of the non-catalytic liquid phase pyrolysis reactions of aromatic model compounds, including naphthalene, anthracene, phenanthrene, pyrene and fluorine, has been summarized.Also, this paper summarized the rule of pyrolysis of aromatics.By comparing the research achievements of domestic and foreign scholars, this paper points out the existing problems in domestic research.Based on the research status of aromatic hydrocarbon compounds, the trend of the study of aromatic hydrocarbon pyrolysis mechanism was prospected.Previous research has the problem of isolated theoretical calculation and experimental research, so the combination of molecular simulation and experimental research should be strengthened.Meanwhile, modern precision analytical instruments should be fully used to analyze experimental products in molecular level.

摘要： 在煤和石油加工过程中，芳烃是重要的生焦初始反应物或中间产物。采用热处理方法制备优质炭材料，如针状焦、碳纤维等，反应过程主要是芳烃的热转化行为，包括缩合和裂解等复杂的反应历程。本文综述了近年来国内外学者采用芳烃模型化合物对芳烃液相非催化热转化反应机理的研究，重点介绍了萘、蒽、菲、芘、芴模型化合物的热转化反应机理，并总结了芳烃热转化反应规律。同时，对采用芳烃模型化合物进行共炭化研究进行了概述。通过对比国内外研究进展，指出国内相关研究存在的问题。基于芳烃模型化合物研究现状，展望了采用模型化合物研究芳烃热转化反应机理的发展趋势。现有研究存在理论计算与实验研究相孤立的问题，因而要加强模型化合物分子模拟计算与实验研究的结合。同时，充分利用现代精密分析仪器对实验产物进行分子水平的解析。
