abstract
Dealumination rate of HZSM-5 zeolite under various water vapor pressures was investigated by means of 27 Al MAS NMR. The dealumination rate was markedly dependent on the water vapor pressure. Under water vapor pressure ranging from 0.1 to 1 kg/cm2, it was found that the dealumination rate was apparently third-order dependent on the content of framework aluminum and approximately 1.5-order dependent on water vapor pressure. Based on these results, a plausible mechanism of dealumination of HZSM-5 zeolite by steaming was proposed.
