Gas phase glycerol dehydration to acrolein using supported silicotungstic acid catalyst

The gas phase dehydration of glycerol to acrolein over a series of supported silicotungstic acid (HSiW) on γ-Al2O3 nanoparticle (W10-Al, W20-Al, W30-Al and W40-Al) has been investigated. The catalysts were characterized by temperature programmed desorption, nitrogen adsorption–desorption, thermograv...
