煤焦油中芳烃化合物催化加氢机理研究进展

Research Progress in Catalytic Hydrogenation of Aromatic Compounds in Coal Tar

煤焦油成分非常复杂,主要是大量的芳烃化合物,此外,还含有少量非烃类的N、S、O杂原子化合物,将芳烃催化加氢饱和以及脱除杂原子N、S、O成为煤焦油加氢精制技术的关键。本研究分别从加氢饱和反应和杂原子脱除反应两个方面分析了煤焦油加氢机理,为后续煤焦油的深加工和开发利用提供理论参考。

The components of coal tar are very complex,mainly a large number of aromatic compounds,in addition,there are also a small number of non-hydrocarbon N,S,O heteroatomic compounds,aromatics catalytic hydrogenation saturation and removal of heteroatomic N,S,O become the key technology of coal tar hydrorefining.This study analyzed the hydrogenation mechanism of coal tar from two aspects of hydrogenation saturation reaction and hetero atom removal reaction,providing theoretical reference for further processing and utilization of coal tar.
