Popis: | Ab initio molecular orbital calculations were performed on model clusters with a geometry derived from the known structure of ferrierite. The data show that siting and pairing of aluminum probably take place preferentially in the six-membered rings. As observed earlier for mordenite and zeolite ZSM-5, charge distribution analyses indicate the highly covalent nature of the zeolitic framework and its behavior as a weak but soft (anionic) base. 26 references, 10 figures, 8 tables. |
