Abstract:

以研究低温煤焦油中特定芳烃组分的选择性分离为目标,通过预处理分离酚类化合物和富集特定芳烃组分,采用多元溶剂萃取方法选择性分离芳烃和非芳烃组分,采用Hansen溶度参数理论进行多元溶剂的设计和萃取条件的优化。结果表明,溶剂对原料焦油的选择性随Hansen溶度参数“距离”(Ra)增加而增大,萃取能力则相反。研究得到的多元萃取剂是含水量为体积分数6%的N,N-二甲基甲酰胺溶液,优化萃取条件是温度25℃、剂/油比6:1。萃余物经多次萃取进一步分离芳烃组分,萃出物经甲酰胺多次萃取以分离出杂环化合物和极性组分。芳烃组分在最终分离产物中的质量分数为94%,其总萃取收率为95%。另外非芳烃化合物、杂环化合物和其他极性组分也在本过程中得到了有效富集。
