英文摘要Acidity and coking activity of (NH4)(2)SiF6 dealuminated faujasites have been investigated by means of infrared spectroscopy. Results show that with the increasing framework Si/Al ratio of (NH4)(2)SiF6 dealuminated Faujasties, (1) Pyridine can interact gradually with the OH groups in the small cavites, while partial OH groups in supercages can not interact with pyridine, (3) the amount of bronsted acid sites decreases, while the amount of its strong part increases. There is no Lewis acid essentially, (4) the coking rate and coke quantity both decrease, which is in consistent with the acidity of faujasites determined by pyridine.
