Abstract:
Gas phase dehydration of glycerol to acrolein over a series of supported HSiW on ZrO2 and nano-sized gAl2O3 catalyst has been investigated. The characterization results revealed that impregnation of g-Al2O3 nanoparticles increased the specific surface area, pore diameter, and thermal stability of the supported catalysts. The highest acrolein selectivity of 88.5% at 97.0% glycerol conversion was achieved over 0.5 g 30HZ-20A catalyst in 3 h at glycerol feed concentration of 10 wt%, temperature = 300 ?C and
TOF = 136 h1. The coke deposition has no significant effect on the activity of 30HZ-20A catalyst. Indeed, the catalyst was stable even after 40 h.
