An efficient bifunctional Ni-Nb2O5 nanocatalysts for the hydrodeoxygenation of anisole
文献摘要：
The Ni-Nb2O5 nanocatalysts have been prepared by the sol-gel method,and the catalytic hydrodeoxy-genation(HDO)performance of anisole as model compound is studied.The results show that Nb exists as amorphous Nb2O5 species,which can promote Ni dispersion.The addition of Nb2O5 increases the acid-ity of the catalyst.However,when the content of niobium is high,there is an inactive Nb-Ni-O mixed phase.The size and morphology of Ni grains in catalysts are different due to the difference of Nb/Ni molar ratio.The Ni0.gNb0.1 sample has the largest surface area of 170.8 m2·g-1 among the catalysts prepared in different Nb/Ni molar ratios,which is mainly composed of spherical nanoparticles and crack pores.The HDO of anisole follows the reaction route of the hydrogenation HYD route.The Ni0.9Nb0.1 catalyst dis-played a higher HDO performance for anisole than Ni catalyst.The selectivity to cyclohexane over the Ni0.9Nb0.1 sample is about 10 times that of Ni catalyst at 220℃and 3 MPa H2.The selectivity of cyclo-hexane is increased with the increase of reaction temperature.The anisole is almost completely trans-formed into cyclohexane at 240℃,3 MPa H2 and 4 h.
