| 中文摘要: |
| 通过将Mg(NO3)3沉淀与碳纳米管(CNTs)上，制备了一系列质量比不同的MgO-CNTs混合并用于费托合成的载体。实验结果表明，在2 MPa，350 oC条件下大部分MgO-CNTs为载体制备的催化剂有着很高的CO转化率，同时，当MgO:CNTs的比例为2:1时，烯烃的选择性高于其他载体制备的催化剂。所有的催化剂用扫描电镜 (SEM），程序升温还原(H2-TPR)，X射线衍射(XRD)和N2物理吸附表征。 |
| 英文摘要: |
| A serious of Magnesia-carbon nanotubes (abbreviated as MgO-CNTs) nanocomposites with different weight ratio were prepared by impregnation of CNTs and used for Fischer–Tropsch synthesis. The results indicated that most of the MgO-CNTs supported catalysts showed high CO conversion and the olefin selectivity was higher than the others when the MgO/CNTs ratio was 2:1 under 2 MPa at 350 oC. The catalysts were characterized by scanning electron microscope (SEM), temperature programmed reduction (TPR) of H2, X-ray diffraction (XRD) and N2 desorption. |
