| Abstract | 采用共沉淀法制各了具有协同稳定作用的Ni/La2O2CO3催化剂，用于山梨醇选择性氢解为小分子醇的研究。采用X射线衍射、氢气程序升温还原、C02程序升温脱附和扫描电镜对催化剂进行了表征。考察了不同配比Ni、La的加氢位点和碱性调控对山梨醇氢解产物的影响。结果表明，Ni、La摩尔比为2：3时，山梨醇转化率达到98.6%，C2~c3多元醇的产率达到43.8%，催化剂经2次反应后对山梨醇的转化率仍高达90%。探究了催化剂从酸性到碱性调变过程中，山梨醇氢解的产物分布，并提出了反应路径。 |
| Other Abstract | Ni/La2O2CO3 catalysts with different Ni/La ratios were prepared by co-precipitation and the performance was tested in selective hydrogenolysis of sorbitol to C2--C3 polyols. The catalysts were characterized by X-ray diffraction(XRD), H2 temperature-programmed reduction(H2-TPR), CO2 temperature-programmed desorption(CO2-TPD) and scanning electron microscopy (SEM). The effect of hydrogenation and base regulation was investigated by varying the Ni / La ratios. The result shows that the conversion of sorbitol was 98.6% and the yields of C2-C3 polyols was 43.8% when the mole ratio of Ni to La is 2:3. After two times of reaction, the catalyst still achieved a sorbitol conversion of 90%. From acidic to alkaline, the products distribution of hydrogenolysis of sorbitol was discussed. The reaction pathway was also proposed based on the experiment results. |
