| Abstract: | Impregnating pitch is a densified reinforcing agent for improving carbon products. Quinoline insoluble matter (QI) in raw coal pitch is removed by solvent-sedimentation method，and then the solvent was removed by distillation under reduced pressure to obtain the impregnating pitch products. The operating conditions of the removal of quinoline insoluble are discussed，including the ratio of solvent，settling temperature，distillation temperature. The comparison of the performance of impregnated asphalt products prepared by the different raw materials are conducted. Impregnating pitch products with 83 ℃ of softening point，0.084% of quinoline insoluble and 49.32% of coking value were obtained. |
