Abstract
The hetero-atomic(B、 Ti、 Fe)zeolite Y was synthesized via hydrothermal synthesis method.The thermal and hydrothermal stability of zeolite USY、 USBY、 USTiY and USFeY were characterized by DSC and XRD.The results showed that titanium in the framework of zeolite Y enhanced the thermal and hydrothermal stability,while boron and iron in the framework reduced the thermal and hydrothermal stability of zeolite Y,especially the hydrothermal stability of zeolite FeY reduced badly.
