γ- Al₂O₃ as a support , a series of tungsten phosphide catalyst s containing vanadium were prepared by the method of co - impregnation and temperature programmed reduction ( TPR) in H₂. The catalyst s were characterized by XRD, BET, TG, XPS. Carbazole hydrodenit rogenation ( HDN) activities of catalyst s were tested by a high pressure micro - reactor in condition of 3 MPa , 360 ℃and a space velocity of 4 h^{- 1}. The result show that dispersity of active species WP on the support surface is affected by adding some content of vanadium into tungsten phosphide catalyst. The cooperative effect is greatly between vanadium and support and active species with vanadium content of 5 %, which resulting in a very smaller changing in XRD pattern. Adding some content of vanadium during the preparation of catalyst produced the original phosphiding-reduction temperature of W species on the support surface for catalyst s precursor increasing and phosphiding - reduction extent decreasing, while the amount of high valence of W⁶⁺ on the surface of catalyst s are improved. Catalyst with vanadium content of 1 % is favor to carbazloe HDN reaction, which gaving 12. 7 % higher carbazole HDN conversion than that without vanadium. It is also observed that carbazole HDN reaction showed three paths: a very low direct denit rogenation selectivity (only 3. 2 %, the first path way ) and a high hydrodenit rogenation selectivity ( hydrogenation to saturating one benzene rings followed by denit rogenation, the second path way, and hydrogenation to saturating two benzene rings followed by denit rogenation, the third path way) . The third path way is a primary rout and the HDN selectivity reached 91. 0 %. Compared to the tungsten phosphide catalyst without vanadium , carbazole HDN selectivity of catalyst with 1 % content of vanadium showed a slightly decreased by the first path and gave a 6. 7 % lower by the third path, 7. 3 % higher by the second path.

The mesoporous materials were synthesized by an nanometer assembly crystallization process and characterized by XRD ，BET ，SEM ，TEM and NH_３－ TPD．The results of XRD show that the zeolite belongs to hexagonal symmetry，and it is a pure phase． The result of N_２ adsorption－desorption isotherm shows that the zeolite has both micropore and mesopore structure and Langmuir surface area is 1135he circumscription blurry．The TEM photos show that the zeolite has dense aperture and inhomogeneous dimension．IR shows that the zeolite presents much more Bronsted and Lewis acidic sites than HMCM －41.The catalytic cracking activity of 1,3,5 triisopropylbenzene over the zeolite is much higher than that over HMCM －41due to its structure and more acid amount.

Diammonium hydrogen phosphate and ammonium metatungstate were used to prepare WP precursor. The impregnation and mixing methods were used to prepare the WP/γ-Al ₂O ₃ precursor with loading of 30%(counting by WO ₃) , respectively. WP/γ-Al ₂O ₃ precursors by adding some content of promoter Ni,Co,V with loading of 30%(counting by WO ₃) were also prepared with impregnation method, respectively. All catalysts were measured with thermogravimetric（TG）analysis in H ₂ flow. The synthetic process of WP catalyst was studied. The effect of synthetic method and promoter on phosphiding extent of WP/γ-Al ₂O ₃ precursor was investigated. The results show that WP precursor can be reduced to WP completely in H ₂ flow. W species on the surface of WP/γ-Al ₂O ₃ precursors prepared by impregnation or mixing methods can not be reduced to WP completely in H ₂ flow . A substance with a similar structure of -Al-O-W-P is probably formed on the support surface. Compared with WP/γ-Al ₂O ₃ precursor by mixing method, W species is more difficult to be reduced to WP on the surface of WP/γ-Al ₂O ₃ precursor by impregnation method. It suggests that inginating reduced temperature of WP/γ-Al ₂O ₃ precursor is obviously decreased by adding promoter nickel(Ni). Cobalt(Co) increases the phosphiding extent of WP/γ-Al ₂O ₃ precursor. Adding vanadium(V) species on the surface of WP/γ-Al ₂O ₃ precursor is more different to be reduced to WP.
