Sustainable production of acrolein: Preparation and characterization of zirco…

Abstract ZrO2-supported H3PW12O40 (HPW) catalysts were used to catalyze the dehydration of glycerol to produce acrolein at 315 8C under a high space velocity (GHSVGlycerol = 400 h1). 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 of alcogel-derived ZrO(OH)2-AN for the support…
