Zhu Jianhua Chunyuan Department of Chemistry, School of Chemistry and Chemical Engineering, Nanjing University Abstract: The main progress in the development of strong alkaline and super alkaline zeolites since the 1990s is reviewed. Zeolite molecular sieves are difficult to change the chemical composition of the framework due to its structural characteristics. The strong base site is generated, the reason why the alkali metal salt supported by the silica alumina zeolite is difficult to produce strong alkalinity is analyzed, and the rule of the neutral potassium salt modification and the preparation of basic zeolite by the magnesium oxide microwave radiation dispersion method is discussed; the structural properties of the carrier are explained The relationship with the formation of super base sites, and the prospects for the development of strong alkaline and super alkaline zeolites.
