Abstract

Mesoporous γ-Al₂O₃with tailoring textural structure was synthesized by precipitation and thereafter hydrothermal treatment in the presence of glucose as a soft template. The effects of various experimental factors on the textural properties of γ-Al₂O₃were investigated using characterization analysis of X-ray diffraction, N₂sorption isotherms, TEM,²⁷Al MAS NMR, and FTIR. The results showed that the mesoporous γ-Al₂O₃in the presence of glucose had the highest surface area up to 429 m²/g, which increased by 100% as compared with the γ-Al₂O₃prepared without template. In the catalytic reaction of ethanol dehydration, the γ-Al₂O₃with higher surface areas caused higher ethanol conversion and ethylene selectivity at the same reaction temperature. The good correlation between the surface area and ethanol conversion suggested that the activity of ethanol dehydration to ethylene is influenced by the surface area of γ-Al₂O₃catalyst.
