| 摘 要： | CO2重整甲烷反应中，采用纳米MgO作为催化剂载体使其具有高的活性和稳定性。纳米MgO的制备以六水氯化镁和氨水为原料，考察了氯化镁的浓度、反应pH、反应温度、中间产物焙烧温度和焙烧介质以及表面活性剂聚乙二醇（PEG）对纳米MgO的影响，并用X射线衍射仪（XRD）、透射电子显微镜（TEM）及物理吸附仪（ASAP-2020）对产物进行了表征。通过适宜工艺条件的控制，制备了粒径约为20 nm、且基本上无团聚的纳米MgO。

| Abstract: | A catalyst using nanoparticle magnesia as the support was prepared for CH4 CO2 reforming system, which exhibited higher activity and stability. The nanoparticle magnesia support was prepared from MgCl2·6H2O and ammonia liquor using PEG as the modifier. Influence of MgCl2 concentration, pH value, reaction temperature, intermediate calcination temperature, calcination medium and surfactant PEG on nanoparticle magnesia was investigated. The resultant samples were characterized by XRD, TEM and physical adsorber (ASAP 2020). Nanoscale magnesia with narrow size distribution and high surface area was obtained with particle size of about 20 nanometer and without agglomeration. |
