Hydrocarbon Transformations Over Analogs And Derivatives Of Zeolite-Y

Zeolites of type Y are prepared by either primary or secondary synthesis. Structures include zeolite Y in both the cubic and hexagonal forms, SAPO-37 and faujasitic frameworks containing Ga or Zn. These materials are characterised using solid state NMR, X-ray powder diffraction, infrared spectroscopy, surface analysis and sorption. Catalysts are then evaluated for the conversion of n-hexane, cyclohexane and gas-oil. Results are interpreted in terms of the effectiveness of catalytic sites in alkane activation and in the effect of both density and distribution of active sites.
