Abstract:
Zeolites Y and ZSM-5 with varying Si/Al ratios are treated in liquid water at 150 and 200 degrees C under autogenic pressure to assess their hydrothermal stability. The changes in the structure are characterized by atomic absorption spectroscopy, X-ray diffraction, scanning electron microscopy, argon physisorption, (27)Al and (29)Si MAS NMR spectroscopy, temperature-programmed desorption of ammonia, and pyridine adsorption followed by IR spectroscopy. During treatment in hot water, zeolite Y wit...     »
