| Abstract: | Y zeolites were modified by steaming and NH 4Cl solution.The influence of modification on the structure and acidity of Y zeolites was investigated.Modified zeolites were studied by TPD,XRD,BET and MP methods to characterize their pore structure,crystal structure and surface acidic properties. When HY was modified by steaming,the crystal type remained unchanged.With increasing steaming temperature,the total acidic comtent,Bronsted acidic Content,crystallinity,surface area of micropore and total surface area of modified Y zeolites all lowered. |
