Manufacture of pitch coke with needle-like structure by mixing pyrolysis oil condensate formed in the process with a coal-tar pitch having a softening point between 70.degree. and 150.degree. C, filtering the mixture at a temperature 100.degree. to 200.degree. C above the softening point, heating the filtrate to a temperature between 450.degree. and 525.degree. C in a tubular heater and coking the heated filtrate in a coking drum, passing volatile pyrolysis products from the drum to a fractionating column for separation of pyrolysis oil condensate from non-condensible gas.
