| Abstract: | XRD, 29Si, 27AI MAS NMR, the adsorption of nitrogen at low temperature,129Xe NMR, XPS, IR-TPD, NH3-TPD, the high vacuum volumetric analysis and pulse flow microreaction were used to study the difference in structure and property between the US-SSY zeolites obtained by quick and slow cooling after treating SSY zeolite with steam at high temperature. The results showed that the cooling rate was one of the important controlling factors during preparing the ultrastabilized Y zeolite. |
