Abstract:
The common main factor of the Na+ influence on the extra-framework aluminum (EFAL) transformations was observed while modeling partly hydrated zeolites at both periodic and cluster computational levels. It can be characterized as the attack of Lewis acid (Na+) toward electron pairs of different O atoms. The limiting step of EFAL formation is assigned to the transformation between the AlOH2+ and View the MathML source species. It allows the explanation of the poisoning effect of Na+ on the cracking reactions known experimentally. The role of electrostatic factor is also discussed.
