| 摘 要： | Using aluminum isopropoxide as the aluminum source and O,O′-bis(2-aminopropyl) polypropylene glycol-block-polyethylene glycol-block-polypropylene glycol as the template,ordered worm-like mesoporous nano-alumina was prepared by sol-gel method.The characterization results showed that the surface area,average pore diameter and pore volume of the calcined mesoporous alumina were 341.1 m2·g-1,17.4 nm and 1.54 cm3·g-1,respectively.The catalytic properties of the mesoporous nano alumina for the dehydration of isopropanol to propylene was investigated.The results indicated that the as-prepared mesoporous nano-alumina exhibited high catalytic activity.The conversion of isopropanol and the selectivity to propylene were more than 99.0% and 98.5%,respectively，when isopropanol WHSV was 0.5 h-1,1.0 h-1 and 2.0 h-1 and the corresponding reaction temperature was controlled at the range of (230-320) ℃,(250-340) ℃ and (260-350) ℃,respectively.
