磷化镍催化剂的制备机理及其加氢脱氮性能
, PP. 335-340
Keywords: 磷化镍,制备机理,热重-质谱,加氢脱氮
Abstract:
？采用热重-质谱联用技术研究了次磷酸盐在氮气中的热分解过程,探讨了次磷酸盐热分解法制备磷化镍的反应机理:次磷酸镍中的ni2+能够"催化"h2po2-低温发生歧化反应生成ph3,继而还原ni2+得到ni2p。制备了不同负载量的ni2p/sio2催化剂,用x射线衍射(xrd)、低温n2吸附-脱附、高分辨透射电镜(hrtem)等分析技术对催化剂结构进行表征。结果表明,ni2p活性组分在sio2载体上具有良好的分散性,颗粒粒径为5～8nm。以喹啉为加氢脱氮模型化合物,在高压微型固定床反应器上对催化剂活性进行评价,在反应温度为360℃、氢气压力为2.0mpa、液时空速为2.0h-1、氢油体积比为500:1时,ni2p(20%)/sio2催化剂的加氢脱氮率为41.5%。
