【摘要】 进行了从低温煤焦油的脱酚混合油中蒸馏切取不同馏分作为废水脱酚萃取剂的试验,结果表明,其分配比和萃取率均高于轻苯和洗油,为低温煤焦油的综合利用开发了新途径。更多还原

【Abstract】 A test that the different fractions obtained by the distillation of the de-phenoilzed oil mixture from low temperature coal tar are used as dephenolizing extractant is carried out. The results show that its mixing ratio and extracting rate are higher than those of light benzol and wash oil, which has developed a new way for the multipurpose utilization of low temperature coal tar.更多还原
