29Si MAS-NMR STUDIES ON DEALUMINATION OF MORDENITE
A series of different H-mordenites from acid leaching and steam calcination have beenmeasured with 29Si NMR. Through analysis of these solid-state 29Si NMR spectra, theresults related to dealumination process of mordenite are obtained. It is shown that mor-denite is combined by four kinds of non-equ...

| description | A series of different H-mordenites from acid leaching and steam calcination have beenmeasured with 29Si NMR. Through analysis of these solid-state 29Si NMR spectra, theresults related to dealumination process of mordenite are obtained. It is shown that mor-denite is combined by four kinds of non-equivalent Si （or Al） via oxygen bridges. The deal-umination order is T（1）, T（2）, T（4） and T（3）. The dealuminated amount in the non-equivalentsites during different dealumination processes has also been discussed in detail. |
