    摘要: A method for producing a cycloolefin and a cycloalkane, which method comprises: a step of hydrogenating a monocyclic aromatic hydrocarbon under an acidic condition in the presence of a catalyst composition, (i) wherein said catalyst composition is a slurry which comprises a ruthenium catalyst, water and zinc sulfate, and which is preserved, prior to being used in said hydrogenation reaction, under a high temperature and high pressure hydrogen atmosphere of from 100 to 200.degree. C. and from 1 to 100 atm for 1 hour or more, and (ii) wherein said hydrogenation reaction is conducted under a controlled pressure, while maintaining a phase separated state of: (a) an oil phase comprising, as main components, the starting materials and the products; and (b) a water phase comprising water as a main component, to thereby control a formation molar ratio of the cycloolefin and the cycloalkane to be formed.
