Abstract
A process is disclosed for the thermal cracking of heavy oil containing nonvaporizable, high-molecular weight hydrocarbone in the presence of steam in one or more thermal cracking tubes or ducts, which process is characterized in that a fluid comprising steam and heavy oil is flowed through a thermal cracking tube such that thermal cracking is carried out under the following conditions: PA0 (a) temperature of the fluid in the thermal cracking tube: 800.degree. to 1100.degree. C. PA0 (b) pressure of the fluid in the thermal cracking tube: 0 to 50 kg/cm.sup.2 G PA0 (c) flow rate or velocity of fluid through the thermal cracking tube: 10 to 100 m/sec, and PA0 (d) residence time of the fluid in the thermal cracking tube: at least 0.2 seconds.
