Direct conversion of bio-ethanol to propylene in high yield over the composite of In₂O₃ and zeolite beta

Abstract

The superior propylene yield of the In₂O₃-beta composite (<italic>ca.</italic> 50%) for the conversion of ethanol to propylene compared to In₂O₃ (<italic>ca.</italic> 32%) is due to the fact that zeolite beta in the composite enhances the conversion of the intermediate of acetone to propylene <italic>via</italic> an additional pathway.
