In this paper,cyclopentanone was used as raw material to prepare cyclopentanol by nickel-based catalyst through fixed bed hydrogenation process.The effects of solvent,reaction temperature,hydrogen pressure,cyclopentanone content and feed space velocity on the reaction were studied,and the process conditions were optimized.Experiments were carried out in a 5 mL catalyst evaluation device.The optimum process conditions were obtained as follows:ethanol was used as solvent,the temperature was 190℃,the hydrogen pressure was 1.5 MPa,ethanol mixture with cyclopentanone content of 15%,and the feed space velocity was 2.16 h-1.The conversion of cyclopentanone was 91.47%,and the selectivity of cyclopentanol was 97.66%.
