It is intended to provide a process for producing an LPG fraction, a gasoline fraction, a kerosene fraction, a light oil fraction, monocyclic aromatic hydrocarbon and a nonaromatic naphtha fraction by converting hydrocarbon oil containing polycyclic aromatic hydrocarbon into a light hydrocarbon fraction and efficiently and selectively producing monocyclic aromatic hydrocarbon. The process for producing a hydrocarbon fraction comprises a hydrogenolysis step of subjecting a raw material hydrocarbon oil which contains polycyclic aromatic hydrocarbon and in which the ratio of carbons constituting an aromatic ring to the total carbons in the hydrocarbon oil is 35% by mole or more to catalytic cracking in the presence of hydrogen, and is characterized in that 40% or more of a fraction with a boiling point of 215°C or higher in the raw material hydrocarbon oil is converted into a fraction with a boiling point lower than 215°C and an oil produced by hydrogenolysis containing 30% by volume or more of monocyclic aromatic hydrocarbon is produced. |
