活性氧化铝载体的研究进展

Research progress of γ-alumina support

由于γ-Al2O3载体的孔结构、表面酸性等性质的可调性,γ-Al2O3载体被广泛应用于催化剂载体领域。催化剂的孔结构、表面性质均取决于γ-Al2O3载体,因此通过掌握γ-Al2O3载体性质的可调变规律就可制备出适合特定催化反应的高性能载体。本文以γ-Al2O3载体制备及γ-Al2O3载体后处理等过程为出发点,详细评述了近年来γ-Al2O3载体的孔结构、表面酸性和水热稳定性等性质调变的最新研究进展,并指明了γ-Al2O3载体今后研究重点和发展方向。

γ-Al2O3 is widely used as catalyst support because of the adjustability of its pore structure and surface acidity.The pore structure and surface properties of catalyst depend on γ-Al2O3 support,so high performance support would be found for specific catalytic reaction by controlling the properties of γ-Al2O3 support.The research progress in the adjustability of pore structure,surface acidity and hydrothermal stability of γ-Al2O3 support is reviewed,including controlling the preparation process of γ-Al2O3 support and its treatment after molding.Finally,research focus and development trend of γ-Al2O3 support are also suggested.
