Abstract

SAPO-34 catalysts were synthesized by hydrothermal method, and characterized by X-ray diffraction (XRD), NH3 temperature-programmed desorption (NH₃-TPD) and thermogravimetric-differential thermal analysis (TG-DTA). The synthesized catalysts were tested for dehydration of bio-ethanol to ethylene in comparison with commercial ZSM-5 and γ-Al₂O ₃. The home-made SAPO-34 catalysts exhibited similar bio-ethanol conversion and ethylene selectivity at 60°C and 110°C lower compared to commercial ZSM-5 and γ-Al₂O₃ catalysts, respectively, indicating higher lowerature activity. It was found that the crystallinity and surface acidity of synthesized SAPO-34 decreased after 4 h on stream, which is attributed to the carbonaceous deposits on catalyst confirmed by TG-DTA.
