Dealumination of ZSM-5 Zeolites with Water [PDF]
Chemistry Letters, 1987 Abstract Dealumination of a framework of H-ZSM-5 zeolites with water was investigated by 27Al MASNMR. It was found that the rate of dealumination is apparently second-order dependent on the concentration of framework aluminium.
