The supported WP catalysts showed considerable activity in HDS reaction of dibenzothiophene and HDN reaction of quinoline. The ibenzothiophene HDS activity and quinoline HDN activity of the spported WP catalysts synthesized by co-impregnation method was better than that synthesized by mixing method. The HDS and HDN activities of 25～30% WP catalysts synthesized by co-impregnation method and reduced at 650～750℃ were better than those of the corresponding sulfurized catalyst.

负载型WP催化剂具有较好的二苯并噻吩加氢脱硫和喹啉加氢脱氮活性，共浸渍法制备的磷化钨催化剂二苯并噻吩加氢脱硫和喹啉加氢脱氮活性要高于混合法制备的磷化钨催化剂。650～750℃还原制备的负载量25～30%的浸渍法磷化钨催化剂具有较高的二苯并噻吩加氢脱硫和喹啉加氢脱氮活性，高于相应的硫化态催化剂。

The results show that WO_3 can be nitrided in the mixture gas of hydrogen and nitrogen, and ...

结果表明，WO3可以在氢氮混合气中被还原氮化；氮化反应分两段进行；在氢氮体积比(4～5)∶1，反应温度650℃的条件下，WO3可以被还原为产物W2N；在不同氢氮比的混合气中氮化，WO3会生成不同的中间产物WO2和WOXNY，中间产物WOXNY进一步氮化生成W2N要比WO2容易；助剂Ni的加入使氮化反应温度降低了100℃；载体γ-Al2O3的加入使金属氧化物的氮化过程变为一步氮化还原反应。
