ABSTRACT:
In methods of manufacturing olefines by thermally cracking hydrocarbons, there is disclosed a thermal cracking method for producing olefines from hydrocarbons, characterized in that hydrocarbon is burnt with oxygen in the presence of steam to generate a high-temperature gas containing steam of 1500.degree.-3000.degree. C.; methane and hydrogen are supplied into the high-temperature gas containing said steam, with the molar ratio of methane to hydrogen in said high-temperature gas being 0.05 or more, then hydrocarbon to be cracked is supplied into said high-temperature gas containing said methane, hydrogen and steam, so that the hydrocarbon is subjected to thermal cracking by maintaining the partial pressure of hydrogen at more than at least 0.1 bar at the outlet of a reactor, under conditions of reaction temperature, 800.degree.-1200.degree. C. and residence time in the reactor 5-300 milli second, and then the reaction product is cooled in a rapid manner.
