    Abstract: PURPOSE:To enable a reaction at high temperature for a short retention time, and to increase olefin yield, by pressurizing a mixed emulsion of a hydrocarbon and water, feeding it to a reactor, preparing an olefin by heating of internal heat method. CONSTITUTION:For example, a combustible gas such as hydrogen, hydrocarbon etc. is burnt with oxygen to prepare a combustion gas at 1,300-2,500 deg.C high temperature, and a raw material of hydrocarbon is fed to the gas. The raw material or hydrocarbon is blended with water to form an emulsion with 5-50wt% water content, which is pressurized by a pump, and fed to preheater. The emulsion is heated by the preheater to a temperature (usually 150- 300 deg.C) to make the fed raw material have
