主　　题：Hydrodeoxygenation(HDO) Catalysts Ni-Nb_(2)O_(5) Solgel method Anisole 

摘      要：The Ni-Nb_(2)O_(5)nanocatalysts have been prepared by the solgel method,and the catalytic hydrodeoxygenation(HDO)performance of anisole as model compound is *** results show that Nb exists as amorphous Nb_(2)O_(5)species,which can promote Ni *** addition of Nb_(2)O_(5)increases the acidity of the ***,when the content of niobium is high,there is an inactive Nb-Ni-O mixed *** size and morphology of Ni grains in catalysts are different due to the difference of Nb/Ni molar *** Ni_(0.9)Nb_(0.1)sample has the largest surface area of 170.8 m^(2)·g^(-1)among the catalysts prepared in different Nb/Ni molar ratios,which is mainly composed of spherical nanoparticles and crack *** HDO of anisole follows the reaction route of the hydrogenation HYD *** Ni_(0.9)Nb_(0.1)catalyst displayed a higher HDO performance for anisole than Ni *** selectivity to cyclohexane over the Ni_(0.9)Nb_(0.1)sample is about 10 times that of Ni catalyst at 220℃and 3 MPa H_(2).The selectivity of cyclohexane is increased with the increase of reaction *** anisole is almost completely transformed into cyclohexane at 240℃,3 MPa H_(2)and 4 h.
