ABSTRACT:
A method for the batch thermal cracking of heavy oils, such as steam blowing for production of binder pitch, employing a reactor having a rotary injection pipe which is rotatable within the reactor. Upon completion of the thermal cracking and withdrawal of the reaction product, the injection pipe ejects preheated raw material under pressure against the interior wall surfaces of the reactor while in rotation to remove coke which has deposited on the reactor walls during the previous cracking operation.
