Hydrocracking of Jatropha oil over Ni-H_3PW_(12)O_(40)ano-hydroxyapatite catalyst

摘要

The Ni-H_3PW_(12)O_(40)ano-hydroxyapatite catalyst with H_3PW_(12)O_(40) (HPW) loading was prepared by impregnation method and performed through hydrocracking of Jatropha oil in a fixed-bed reactor. The catalyst was characterized by N_2 adsorption-desorption, powder X-ray diffraction (XRD), Fourier transform infrared (FT-IR), X-ray photoelectron spectroscopy (XPS), temperature-programmed desorption of ammonia (NH3-TPD), thermogravimetric analysis (TGA). The conversion of Jatropha oil over Ni-HPW (30 wt%)HA was 100%, the liquid yield of liquid product was 83.4%, the ratio of i-paraffins was 1.64 at 360 ℃, 3 Mpa, H_2/oil (v/v) = 600 and LHSV = 2 h~1. The pour point of final product oil was -28 ℃ and the catalyst was used without sulfurization.
