Abstract

MFI type zeolites were synthesized with chromium and gallium. Hydrothermal synthesis was applied using, either aluminum with gallium or chromium sources in 1:1 mole ratios, or impregnation of H-ZSM-5 with the desired metal. Propylene yield and selectivity over Ga- and Cr-modified H-ZSM-5 zeolites increased remarkably with the steaming of the catalysts, as a consequence of the suppression of their acidity and therefore of the dramatic decrease of their oligomerization capability. Thus, Ga- and Cr- modified steamed zeolites are promising catalysts for the dehydrogenation of propane to propylene. This is an abstract of a paper presented at the International Workshop on Oxide Based Materials: New sources, novel phases, new applications (Como, Italy 9/13-16/2004).
