Simone, A A

Coal tar pitch is contacted with a promoter liquid having a 5 volume percent distillation temperature of at least 250/sup 0/F and a 95 volume percent distillation temperature of at least 350/sup 0/ and no greater than about 750/sup 0/F, with the liquid having a characterization factor of at least 9.75 to promote the separation of quinoline insolubles from the pitch. A coal tar pitch fraction essentially free of quinoline insolubles is then subjected to coking to produce a needle coke. The process is also applicable to separation of quinoline insolubles from coal tar derived binder pitch.
