负载型催化剂中载体对催化剂的加氢作用影响很大。通过γ- Al2 O3改变来研究载体对负载型纳米加氢催化剂的影响。本实验用浸渍方法在γ- Al2 O3上负载一层 Ti O2 。通过控制浸渍溶液的浓度制成一系列不同含量的 Ti O2 改性γ- Al2 O3载体。然后用物理法将纳米 Ni粉体加载到改性载体上 ,制成一系列改性催化剂。结果表明 Ti O2 含量不同的催化剂活性不同 ,在质量分数为 3.6%时出现一个极大值。在 XRD谱图中 ,即使 Ti O2 质量分数达到 1 4.5 % ,谱图中也没有明显的 Ti O2 峰出现 ,这说明 Ti O2 在 γ- Al2 O3分散性极好 The supported catalyst has a great influence on the hydrogenation of the catalyst. The influence of the support on the supported nano-hydrogenation catalyst was investigated by the change of γ-Al 2 O 3. In this experiment, a layer of Ti O2 was loaded on γ-Al 2 O 3 by impregnation method. By controlling the concentration of impregnation solution, a series of Ti O2 modified γ-Al2 O3 carriers with different contents were prepared. Then nano-Ni powder is loaded onto the modified carrier by physical method to make a series of modified catalysts. The results show that the catalysts with different Ti O2 contents have different activity, and a maximum at 3.6% is obtained. In the XRD spectrum, there is no obvious Ti O2 peak in the spectrum even though the mass fraction of Ti O2 reaches 14.5%, which shows that Ti O2 has excellent dispersibility in γ-Al 2 O 3
