Abstract

A pyrolysis fuel oil (black oil) is contacted with a promoter liquid having a 5 volume percent distillation temperature of at least 250.degree. F. and a 95 volume percent distillation temperature of at least 350.degree. F. and no greater than about 750.degree. F., with the liquid having a characterization factor of at least 9.75 to promote the separation of quinoline insolubles and asphaltenes from the fuel oil. A fraction free of quinoline insolubles and having a reduced content of asphaltenes may be subjected to coking to produce a needle coke, or employed directly for the production of carbon black.
