Abstract:

Four factors affecting the sedimentation performance of coal pitch are respectively analyzed in this paper with coal pitch as feedstock and with aromatics and aliphatic hydrocarbon as extractant by process of solvent extraction-standing sedimentation so that the sedimentation behavior of coal pitch can be evaluated quickly and accurately.The result shows the appropriate working conditions as aromatic lipid ratio 1∶0.6,solvent to feed ratio 1∶1,treatment temperature 130℃ and sedimentation time 4 hours,which is characterized with convenience,being quick,rationality and low investment.
