摘要
本文介绍了离心沉降法净化煤焦油的试验情况。试验室试验表明,在最佳操作条件下,QI脱除率达95～98％,即保证净化煤焦油中的QI含量低于0.1％(重量)。同时,进行了添加溶剂(脱酚酚油、洗油)试验。
The experiment on purifying the coal tar by the centrifugal settling method is described in this paper. The bench-scale experiment indicates that QI removal rate can reach 95-98% under optimal test conditions, it can be warranted to be lowered to<0.1% (wt) in purifying the coal tar. At the same time, the experiment is performed by additive solvent (dephenolized carbolic oil, wash oil).
