Abstract
Effect of alkali metal cations on dealumination of a framework of ZSM-5 zeolite with water was investigated by using 27Al MASNMR and FT-IR. It was found that under the steaming conditions of 600 °C for 13.5 h, dealumination of the zeolite is quantitatively controlled by alkali metal cations introduced by an ion-exchange method, leaving framework aluminium in the concentrations nearly equal to those of the metal cations.Keywords
