摘要 煤直接转化液体产物中除含有大量的酚类化合物外,还含有一些其他含氧含氮化合物,这些物质对于酚的萃取分离具有重要影响。采用乙二醇-尿素复配溶剂作为萃取剂,考察了萃取剂中尿素含量、搅拌时间、静置时间、温度以及萃取剂使用量对煤直接转化液体产物模拟油中酚类化合物萃取效果的影响,探究了模拟油中杂原子化合物苯乙酮、吲哚、吡啶对酚类分离效果的影响。结果表明:乙二醇-尿素复配溶剂对间甲酚的萃取效果要明显优于尿素,搅拌时间为20 min,静置时间为10 min时就可达到萃取平衡,升高温度不利于萃取,间甲酚萃取率随着萃取剂使用量的增加呈现先增加后趋于平缓的趋势,当温度为25℃、m(萃取剂):m(模拟油)(剂油比)为1:1时,乙二醇-尿素复配溶剂对间甲酚萃取率可达99.2%;模拟油中添加苯乙酮、吲哚、吡啶均会降低萃取剂对间甲酚的萃取率,相对于苯乙酮和吲哚,吡啶对间甲酚分离影响最大,可使间甲酚萃取率降低到71.6%。

Abstract: The products of direct liquefaction of coal contain a large number of phenolic compounds and other oxygenated or nitrogenous compounds, which have direct impacts on the extraction and separation of phenols. In this paper, glycol-urea composite extractant was used as extractant, the effects of urea content in extractant, stirring time, static time, temperature and extractant usage on the extraction of phenols in the model oil were investigated. The effects of acetophenone, indole and pyridine on the separation of phenols were also investigated. The results showed that the extraction effect of m-cresol by glycol-urea composite extractant is significantly better than urea. When the stirring time was 20 min and the static time was 10 min, the extraction equilibrium could be reached. The increase of temperature was not conducive to extraction. Extraction efficiency of m-cresol increased first and then stabilized with the increase of extractant usage. The extraction efficiency of m-cresol could reach 99.2% at 25℃ and the mass ratio of extractant to model oil was 1:1. Adding acetophenone, indole, and pyridine to the model oil will reduce the extraction efficiency of m-cresol. Compared to acetophenone and indole, pyridine has the greatest effect on the separation of m-cresol, which can reduce the m-cresol extraction to 71.6%.
