ABSTRACT:
Continuous production of coke by pyrolysis of a hydrocarbon mixture containing petroleum tar, coal tar pitch or pyrolysis tars in which the hyrocarbon mixture and recycled condensate is heated in a preheater at a rate to increase the mesophase content of the mixture up to 30 to 60%; the preheated mixture is then heated in a coking zone at a rate to form a raw coke having a mesophase content of 70 to 100%; continuously removing the raw coke from the coking zone and heating it in a calciner. The coke produced is more uniform and the process more efficient.
