Zhu Jianhua Chunyuan Department of Chemistry, School of Chemistry and Chemical Engineering, Nanjing University Abstract: An overview of the main progress in the development of strong alkaline and ultra-strong alkaline zeolites at home and abroad since the 1990 s, zeolite molecular sieves due to its structural characteristics, it is difficult to change the chemical composition of the framework to produce strong base sites, analysis of the silica-alumina zeolite load alkali metal salt difficult to produce strong alkaline, to explore the neutral potassium salt modification and magnesium oxide microwave radiation dispersion preparation of alkaline zeolite law; the relationship between the structural properties of the carrier and the formation of superbasic sites is described, and the development direction of the development of strong and superbasic zeolites is prospected.
Keywords: strong basic molecular sieve solid super alkali zeolite catalytic material molecular sieve
