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.
