摘要
热解是煤转化过程中重要基础,其实质是自由基反应过程.自由基的形成、转移和稳定对于理解煤热解过程机理与产物生成至关重要.详细综述了煤中自由基研究方法,煤中固有自由基同煤自身性质的关系,以及煤转化过程中自由基形成和演变行为的研究进展与现状.最后结合煤中自由基研究面临的困难和挑战,指出了煤转化过程自由基研究在未来的发展方向.
Coal pyrolysis is the important basis of coal conversion and its essence is the process of free radicals reaction. The formation, transfer and stabilization of free radicals are essential for under- standing the mechanism of coal pyrolysis process and the composition of products. The research method of free radicals in coal and the relation between the native free radicals and coal properties, and the research situation of the formation and transformation of free radicals in coal conversion process were summarized in details. Finally, based on the difficulties and challenges of investiga- tion into coal free radicals, the study on coal-derived free radicals in the future development direc- tion is presented.
