Abstract A preparation method of cyclopentane includes the following steps: depolymerizing dicyclopentadiene in depolymerization reactor at 160-400 deg.C in the presence of hydrogen gas and diluent under the condition of system pressure of 0.1-2.5 MPa to obtain cyclopentadiene, then making the cyclopentadiene undergo the process of hydrogenation treatment in fixed bed reactor with head-exchange device at 10-100 deg.C to obtain cyclopentane, and collecting said product. The yield of cyclopentane can be obviously raised, can be up to above 70%, and the service life of catalyst also can be prolonged.
