Production of Ethylene from Ethanol Dehydration over H3PO4-Modified Cerium Oxide Catalyst

Production of ethylene from ethanol dehydration was investigated over H3PO4 (10wt% to 30wt%)-modified cerium oxide catalysts synthesized by wet impregnation technique. The prepared catalysts were characterized using scanning electron microscope (SEM), N2 adsorption-desorption method, X-ray diffracti...
