摘要

PROBLEM TO BE SOLVED: To provide a modified tar which can provide needle coke and raw coke suited for the production of needle coke.;SOLUTION: A hydrogen-donating solvent in an amount of 30-300 pts.mass is added to 100 pts.mass coal-derived low-temperature tar or coal-derived pitch obtained by removing light fractions from coal-derived low-temperature tar, and the resultant mixture is kept at 380-450°C for 0.1-4 hours under a pressure of 0.3-5.0 MPa.;COPYRIGHT: (C)2011,JPO&INPIT
