摘要：
A method for preparing a ruthenium catalyst, including a step of reducing a ruthenium catalyst precursor by holding the ruthenium catalyst precursor in an aqueous solution containing a metal salt at a temperature within the range of more than 180° C. and 220° C. or less and a hydrogen partial pressure within the range of 0.6 MPa or more and 5 MPa or less. A method for producing a cycloolefin, including a step of preparing a ruthenium catalyst by the method including a step of reducing a ruthenium catalyst precursor in an aqueous solution containing a metal salt by holding the ruthenium catalyst precursor at a temperature within the range of more than 180° C. and 220° C. or less and a hydrogen partial pressure within the range of 0.6 MPa or more and 5 MPa or less, and a step of partially hydrogenating a monocyclic aromatic hydrocarbon by use of the ruthenium catalyst obtained.
