METHOD OF THERMALLY CRACKING HEAVY PETROLEUM OIL Abstract of the Disclosure The specification discloses a method of thermally cracking a heavy petroleum oil by introducing the heavy petroleum oil, heated in advance, into a reactor and contacting the heavy petroleum oil with a gas which does not react with the heavy petroleum oil at a temperature of 400 - 2000°C thereby thermally cracking the heavy petroleum oil therein, the method including using several reactors in succession so that the reaction can be carried out essentially continuously, and charging each reactor in advance with an amount of the heavy petroleum oil at a temperature lower than the reaction temperature. In this way, excessive coking of the oil can be prevented and the reactors are subjected to less thermal shock, and therefore damage, when the main charge of heated oil is introduced.
