Abstract: Nickel phosphide (Ni-P) catalyst was prepared by a solvothermal method using ethylene glycol
as solvent, NiCl 2·6H 2O and NaH 2PO 2·H 2O as nickel source and phosphorous source respectively, where the
molar ratio of phosphorus to nickel was 3 : 1. The sample was characterized by XRD, SEM, TEM, H 2-TPR,
H 2-TPD, N 2 adsorption-desorption and XPS. The effects of dosage of catalyst, hydrogen pressure, reaction
temperature and reaction time on the hydrogenation of furfural to cyclopentanone were evaluated. The
results showed that the optimal process conditions were: water as solvent, mass ratio of raw material to
catalyst 12, reaction temperature 150 ℃, hydrogen pressure 2.0 MPa and reaction time 4 h. Under these
conditions, the conversion of furfural and the yield of cyclopentanone reached 98.87% and 68.65%,
respectively. In addition, the stability test of Ni-P was carried out. It was found that there was no obvious
decrease in the catalytic activity of the reused catalyst even after being recycled four times. The yield of
cyclopentanone decreased by only 3.25%.
