由表征数据分析可知，与原料蒙脱土相比，蒙脱土负载型催化剂具有明显的布朗斯特酸位和路易斯酸位，酸性得到增强，层间距明显增大，晶型保持良好，比表面积和孔容变大，平均孔径减小，无机盐分布比较均匀，并且具有良好的热稳定性。
The characterization results demonstrate that, compared to the starting montmorillonit, the montmorillonite supporting the catalyst has apparent Brφnsted acid sites and Lewis acid sites, which enhances the acidicity thereof. In addition, the montmorillonite supporting the catalyst has drastically increased interlamellar spacings, well-retained crystilline types, increased specific suface area and pore volumens, and reduced average pore diameters. Furthermore, the montmorillonite supporting the catalyst has evenly distributed inorganic salt, and good thermal stability. |
