摘要
对炭素厂浸渍后的废沥清再生的可能性进行了研究。研究表明浸后废沥青可以通过离心分离法脱除其中的固形杂质及喹啉不溶物，喹啉不溶物的脱除率与废沥青稀释剂的溶剂比有关，所得再生沥青的喹啉不溶物的含量均低于炭素厂对粘结剂和浸渍剂的要求。
The possibility of the regeneration of waste pitch of impregnation process in carbon plant has been investigated. The result shows that the quinoline insoluble (QI) and solid impurity can be eliminated from waste pitch by centrifugal separation method. The percentage of eleminated QI varies with tile ration of dilution solvent. QI content of regeneration pitch is lower than that of binder and impregnant in carbon plant.
