ZrO 2 -supported H 3 PW 12 O 40 (HPW) catalysts were used to catalyze the dehydration of glycerol to produce acrolein at 315°C under a high space velocity (GHSV Glycerol =400h −1 ). The catalysts were prepared by varying the loading of HPW on two ZrO(OH) 2 supports of different preparations, followed by calcination in flowing nitrogen. The use...
Gas-phase dehydration of glycerol to produce acrolein was investigated at 315 °C over Nb 2 O 5 catalysts calcined in the temperature range of 350–700 °C. The catalysts were characterized by nitrogen physisorption, TG-DTA, XRD, and n-butylamine titration using Hammett indicators to gain insight into the effect of calcination temperature on catalyst texture, crystal structure, and acidity...
