ous catalysis. A novel catalyst of BC supported alumina (Al O ) was developed by soaking purified BC hydrogel in 2 3 aluminum nitrate (Al(NO ) ) aqueous solution, dehydration 3 3 (hot air drying and freeze-drying) and calcination. The Al/ BC catalysts reveal interior meso–macro porous structures with average pore diameters in the range of 17–34 nm. The catalytic activities were examined through an ethanol dehy- dration reaction in the gas phase at atmospheric pressure in the range of 200–400 °C. The effects of acidic metal load- ing and dehydration methods were investigated. Increasing Al loading from 12 to 50% resulted in a decreased surface area but an increase in pore size. At the same Al loading, the catalysts with a dehydration process by hot air drying presented higher Al concentrations on the outer surface compared with those by freeze-drying. At high tempera- ture of 400 °C, Al/BC catalysts with 25 wt% Al loading and Keywords Catalyst support · Composites · Reaction · dehydrated by freeze drying (25Al/BC FD) and 50 wt% Al Bacterial cellulose · Alumina · Ethanol dehydration loading, dehydrated by hot air drying (50Al/BC TD) exhib- ited the highest ethanol conversions of 65.7–66.4% and ethylene yields of 43.26–44.24%, respectively, whereas at 1 Introduction
