METHOD FOR THERMAL CRACKING OF HEAVY PETROLEUM OIL Abstract of the Disclosure The specification discloses a method for the thermal cracking of a heavy petroleum oil by feeding the heavy petroleum oil into a reaction system and bringing it therein into contact with a gas which does not react with the heavy petroleum oil, at a temperature in the range of from 400°C to 2000°C. The method includes the use, as the reaction system, of a plurality of reactor vessels arranged in series and in which the interior temperatures are successively lowered by at least 3°C in the direction of the transfer of the charge. In this way, the aromatic hydrocarbon pitches thus produced are of good quality and can be obtained in high yield. -1-
