The ultra-stable zeolite DASY-0.0 was prepared by hydrothermal method in commercial scale.Its structure was further modified via the treatment for cleaning of pores(CP).The zeolite samples before and after CP treating were analyzed and characterized by XRF,XRD,NMR,IR,BET and DTA.The results showed that,in comparison with the conventional ultra-stable zeolite DASY-0.0 prepared by the hydrothermal process,the CP-modified zeolite SOY0 exhibited a higher relative crystallinity.a larger surface area and pore volume,a higher thermal stability and contained less amorphous non-framework Al.
