摘要
酚类化合物是煤炭直接液化产物中具有较高附加值的主要含氧化合物,也是煤液化油酸性物质的主要成分。它不仅对油品的提质加工的技术路线有影响,而且也对煤炭直接液化的经济性具有较大的影响。由于该方面的研究工作尚属起步阶段,借鉴煤焦油和石油系产品中酚类化合物的有关分离与利用情况,结合笔者的研究实践和认识,提出了在煤直接液化油中酚类的分离与利用方面应开展的工作和研究方向。
Phenolic compounds are the predominant oxygen-containing compounds which have high value-added in direct coal liquefaction products, also are the major components of the acid substances in coal liquids. It has large impact on the oil＇s hydro-upgrading technology courses and economy of the direct coal liquefaction. As this study work in the initial stage, the authors put forward work and research direction about the separation and utilization of the phenolic compounds referring the coal tar and petroleumg products separation and utilization and combining the authors＇ practices and knowledge.
