Dehydration of glycerol to acrolein was performed on WO3/ZrO2 solid heterogeneous catalysts in a continuous flow fixed bed reactor. A maximum of 75% acrolein selectivity was achieved at 100% conversion of glycerol. The acrolein selectivity correlates with the concentration of weak acidic sites of the WO3/ZrO2 catalysts that were free of basic sites.
