摘要
氧化铝催化剂载体领域中,γ-Al2O3应用最为广泛。文章综述了γ-Al2O3载体的应用、制备工艺,并总结了制备方法的改善,添加助剂和选择合适的前驱体的方法,对活性氧化铝进行改性,开发出大比表面积、适宜孔径分布及热稳定性良好的γ-Al2O3载体的研究成果。
γ-alumina has been used most widely in the area of alumina catalyst carrier.In the paper,the application and the preparation technology of active alumina catalyst carrier were reviewed.Furthermore,the active alumina was modified by improving the method of preparation,adding agents and choosing the right precursor.Catalyst carriers including γ-alumina with larger specific surface area,suitable pore size distribution,excellent thermal stability was developed.
