aqueous solutions were prepared

and characterized by inductively coupled plasma(ICP)

X-ray diffraction(XRD)

Fourier transform-infrared spectroscopy(FT-IR) and temperature-programmed desorption of ammonia

They are of lower Si/Al ratio and higher acid amount while keeping a high relative crystallinity.Their catalytic per-formances were evaluated with the liquid-phase
