The Pt-supported USY zeolite catalysts doped with Cr, Al or Zn were prepared by impregnation, and characterized by XRD, low temperature nitrogen physisorption, H2-chemisorption and IR spectroscopy of the pyridine adso...
The Pt-bearing SO42-/ZrO2 superacid catalysts supported on ultra stable Y (USY) zeolite were prepared by impregnation and characterized by X-ray diffracti on, nitrogen adsorption and Hammett indicators. Their catalyti...
