Aromatic hydrocarbons are important components of petroleum-based transportation fuels, biomass, coal, and solid waste, etc. The reaction kinetics of aromatic hydrocarbons largely determine the combustion characteristics and pollutant emission of vehicle/jet engines, power plants, and industrial reactors. While a few reviews have recently focused on aromatic hydrocarbons in gasoline surrogate fuels, thermochemical conversion of biomass/coal/solid waste, and combustion soot formation, a dedicated overview of research on the combustion chemistry of aromatic hydrocarbons is still lacking. In the last decades, valuable investigations addressing the reaction kinetics were reported based on the measurements from pyrolysis, oxidation, flames, shock tubes, and rapid compression machines, complemented by quantum chemistry and detailed kinetic modeling. Significant advances have allowed a better understanding of such physicochemical reacting system, from aromatic decomposition, oxidation, to pollutants formation. In the present review, aromatic hydrocarbons are systematically categorized to five common classes: basic, mono-substituted, multi-substituted, hydrogenated, and polycyclic aromatics. Fundamental aromatic combustion chemistry consists of the reactions of basic aromatic molecular structures. Then the aryl group strongly influences the reaction kinetics of aromatic derivates, which leads to very different combustion performance from those ordinary paraffins, olefins, and naphthenes. This paper seeks to provide an introduction to the knowledge gathered in the recent research, highlight pertinent aspects of this rapidly enriching information, and outlook the challenges towards fundamentally comprehensive aromatic combustion chemistry and practically efficient aromatic combustion model.

芳烃的燃烧化学

芳烃是石油基运输燃料、生物质、煤和固体废物等的重要组成部分。芳烃的反应动力学在很大程度上决定了车辆/喷气发动机、发电厂和工业反应器的燃烧特性和污染物排放。虽然最近有一些评论集中在汽油替代燃料中的芳烃、生物质/煤/固体废物的热化学转化以及燃烧烟灰的形成,但仍然缺乏对芳烃燃烧化学研究的专门概述。在过去的几十年里,基于热解、氧化、火焰、激波管和快速压缩机的测量,辅之以量子化学和详细的动力学建模,报告了针对反应动力学的有价值的研究。重大进展使人们能够更好地理解这种物理化学反应系统,从芳香族分解、氧化到污染物形成。在本综述中,芳烃被系统地分为五个常见类别:碱性、单取代、多取代、氢化和多环芳烃。基本芳烃燃烧化学由基本芳烃分子结构的反应组成。然后芳基强烈影响芳烃衍生物的反应动力学,这导致与那些普通的链烷烃、烯烃和环烷烃有很大不同的燃烧性能。本文旨在介绍最近研究中收集的知识,突出这一迅速丰富的信息的相关方面,
