ABSTRACT:
A process for selectively producing olefins and aromatic hydrocarbons by thermal cracking of hydrocarbons which comprises the steps of: burning hydrocarbons with oxygen in the presence of steam to produce a hot gas of from 1300.degree. to 3000.degree. C. comprising steam; feeding a heavy hydrocarbon to the hot gas to thermally crack the heavy hydrocarbon under conditions of a temperature not lower than 1000.degree. C., a pressure not higher than 100 kg/cm.sup.2 g, and a residence time of from 5 to 20 milliseconds; further feeding a light hydrocarbon downstream of the feed of the heavy hydrocarbon in such a way that a light hydrocarbon with a lower boiling point is fed at a lower temperature side downstream of the feed of the heavy hydrocarbon, thereby thermally cracking the light hydrocarbon under conditions of a reactor outlet temperature at not lower than 650.degree. C., a pressure at not higher than 100 kg/cm.sup.2 g, and a residence time at 5 to 1000 milliseconds; and quenching the resulting reaction product.
