离子型表面活性剂对煤沥青制分离行为的影响 -

以QI含量为5.3%的中温煤焦油沥青为原料在420～470℃时聚合90min,得到含中间相小球的母液,采用溶剂热过滤方法分离,对比添加离子型表面活性剂对母液分离效率及得到产品收率、性能的影响,所得中间相炭微球的球形结构较好,作为锂电池负极材料电性能优良,且较显著提高分离效率。 The middle temperature coal-tar pitch with 5.3% QI is condensated for 90 minutes at 420～470℃,then the liquor that contains MCMB is separated by heating filtering. When some ionic-surfactant is put in the process of filtering,the separation efficiency and yields are higher than before. The MCMB's sphericity is better,and its electrochemical performance as carbon material for Li battery anode is perfect
