Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an energy-saving low-cost method for the hydrocracking of crude oil necessitating remarkably reduced space of a refinery plant. SOLUTION: Crude oil subjected to pretreatment such as desalting is pressurized, heated, sealed in a high-pressure hydrogen tank, maintained to 50-120 kg/cm2G and 250-350°C, and decomposed by adding a decomposition-promoting additive such as naphtha containing sulfur, cumene, cymene, ethylbenzene, butyl mercaptan, benzothiophene and H2S in an amount of 3-10% or more.
