中文摘要：
采用免焙烧的方法,直接将Ni（NO3）2和（NH4）2HPO4盐的前驱体,或是担载Ni（NO3）2和（NH4）2HPO4盐的前驱体通过氢等离子体法（PR）制备了Ni2P-NC-PR,Ni2P（25）/Si O2-NC-PR加氢脱硫催化剂。以质量分数为0.8%的二苯并噻吩/十氢萘溶液为模型化合物,考察了催化剂的HDS反应性能,并用XRD对催化剂晶相进行了表征。新鲜制备的催化剂在移入固定床反应器之前用体积分数10%H2S/Ar钝化,以保护其结构不被破坏。实验证明,PR还原法制备的Ni2P-NC-PR催化剂的加氢脱硫活性高于Ni2P-C-PR催化剂,PR还原法制备的Ni2P（25）/Si O2-NCPR催化剂的加氢脱硫活性高于Ni2P（25）/Si O2-C-PR催化剂。XRD表征结果表明：Ni2P-NC-PR或Ni2P（25）/Si O2-NC-PR催化剂的颗粒尺寸都小于Ni2P-C-PR或Ni2P（25）/Si O2-C-PR催化剂的颗粒尺寸,催化剂的活性中心较多,其高活性可归于其活性中心数量的增加。
英文摘要：
Ni2P-NC-PR and Ni2P（25）/SiO2-NC-PR hydrodesulfurization （HDS） catalysts were prepared by noncalcination method, in which the precursors containing Ni（ NO3 ）2 and （NH4 ）2HP04 were directly converted to the active phosphide phase by hydrogen plasma reduction （ PR ） method. The HDS performances of the prepared catalysts were studied by using a model fuel containing mass fraction 0.8% dibenzothiophene in decalin, and the morphologies of the catalysts were characterized by XRD. A mixture of volume fraction 10% H2S/Ar was used to passivate the freshly synthesized catalysts to protect the crystal structures before entering the fixed bed reactor. Experimental results show that the hydrodesulfurization performances of Ni2P-NC-PR and Ni2P （25）/SiO2-NC-PR prepared by PR method are higher than that of Ni2 P-C-PR and Ni2 P （25）/SiO2-C-PR respectively. XRD characterization results reveal that the catalyst particle size of Ni2P-NC-PR or Ni2P （25）/SiO2-NC-PR is less than that of Ni2P-C-PR or Ni2P （25）/SiO2-C-PR. The catalyst active center of Ni2P-NC-PR or Ni2P （25）/Si02-NC-PR is more, and its high activity is attributed to the increase in the number of the active center.
