中文摘要：
采用氢等离子体还原法制备了体相Ni2P,新鲜制备的Ni2P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：氢等离子体（PR）还原法制备的Ni2P催化剂的加氢脱硫活性高于程序升温还原（TPR）法制备的催化剂。XRD表征结果表明,氢等离子体还原法制备的Ni2P的粒度较小,活性中心较多,其高活性可归于其活性中心数量的增加。氢等离子体还原法制备的Ni2P具有良好的反应稳定性。
英文摘要：
The bulk Ni2P was synthesized by means of hydrogen plasma reduction（ PR）. A mixture of 10% H2S in Ar was used to passivate the freshly-synthesized Ni2P to protect their crystal structures before entering the fixed bed reactor. The experimental results show that their catalytic performances are higher in the hydrodesulfurization（ HDS） than those prepared by the conventional temperature-programmed reduction（ TPR） method. XRD characterization results reveal that there exist more active sites in the PR-synthesized Ni2P than in the TPRsynthesized ones due to the decreased particle sizes of the PR-synthesized Ni2P. The PR-synthesized Ni2P exhibits a good stability during HDS reaction.
