| 摘 要： | 采用共沉淀的方法制备了以镍为活性组分、镁为助剂、 SiO_2为载体的Ni-Mg/SiO_2催化剂,以大豆油加氢为探针反应研究催化剂中残留Na的含量对加氢活性的影响.分别用ICP-AES、 XRD、 H_2-TPR、 TG-DSC、 SEM、 BET等手段对不同催化剂进行了表征.结果表明:催化剂中残留Na对加氢活性有很大影响, Na含量为6.86%时,催化剂基本没有活性.随Na含量的降低,催化剂活性逐渐升高.这主要是由于Na对Ni的分散、颗粒尺寸和与载体相互作用有较大的影响有关.

| Abstract: | A series of Ni-Mg/SiO2 catalysts with the different residual Na contents were prepared by co-precipitation method. Soybean oil hydrogenation was used as a probe reaction to study the effect of residual Na content in the catalyst on the hydrogenation activity. The catalysts were ?characterized by ICP-AES, XRD, H2-TPR, TG-DSC, SEM and BET. As a consequence, the residual Na in the catalyst has a great effect on the hydrogenation activity. The catalyst was basically inactive when the Na content was 6.86%, while the activity of hydrogenation to soybean increased with the drop of sodium exsited in nickel catalyst. It suggested that the residual Na would affect on the dispersion and particle size of Ni, and the interaction with the support between Ni and the support. |
