煤焦油加氢脱氧精制研究进展

摘要

简要介绍了煤焦油中主要含氧化合物的类型，包括酚类、萘类、酯类、酸类、呋喃类和醛类等含氧化合物，综述了不同类型含氧化合物在加氢脱氧( HDO)过程中的反应机理以及反应路径，总结了加氢脱氧过程中直接脱氧和间接脱氧的相互关系以及路径选择，最后针对煤焦油中含氧化合物复杂及多样性的特点提出了一些新的改进和研究方向，并对含氧化合物加氢脱氧的未来作了展望。%The types of the main oxygen-containing compounds in coal tar were briefly described, including phenols, naphthalene, esters, acids, aldehydes, furans and other oxygen-containing compounds, and the reaction mechanisms about different types of oxygen-containing compounds in hydrodeoxygenation ( HDO ) process was simply introduced. Meanwhile, reaction mechanism and pathway of different types of oxygen-containing compounds were also reviewed. The directly and indirectly in the process of HDO and path selection were summarized. For a complexity and diversity of oxygenated compounds contained in the coal tar, a number of improvements and new research directions were made. In addition, the prospect of oxygen-containing compounds HDO was discussed.
