Characterization of Ni2P/rGO-Al2O3 Catalyst and Its Catalytic Performance in Hydrodeoxygenation

Using flake graphite as raw material, graphite oxide (GO) was synthesized by hummer method, and GO was mixed with pseudo-boehmite solution to synthesize reduced graphene oxide-alumina (rGO-Al2O3) composite support. Then, Ni2P/rGO-Al2O3 catalyst was prepared by impregnated method. The catalysts were characterized by scanning electron microscopy (SEM), physical adsorption (BET) and X-ray diffraction (XRD). The performance of Ni2P catalyst supported on rGO-Al2O3 composite support and rGO or Al2O3 alone in hydrodeoxygenation (HDO) was compared, under the conditions of reaction temperature of 300℃, pressure of 2.5 MPa and reaction time of 4 h with benzaldehyde as substrate. Results show that the rGO-Al2O3 has abundant of pore structure and large surface area, and the Ni2P/rGO-Al2O3 catalyst shows excellent catalytic activity and selectivity. © 2019, Editorial Office of Acta Petrolei Sinica(Petroleum Processing Section).
