Production of Ethylene From Ethanol Dehydration Over H3PO4-Modified Cerium Oxide Catalysts = Penghasilan Etilena Daripada Pendehidratan Etanol Dengan Mangkin Serium Oksida Terubahsuai H3PO4

Production of Ethylene From Ethanol Dehydration Over H3PO4-Modified Cerium Oxide Catalysts = Penghasilan Etilena Daripada Pendehidratan Etanol Dengan Mangkin Serium Oksida Terubahsuai H3PO4

Production of ethylene from ethanol dehydration was investigated over H3PO4 (10 wt.% 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 diffra...
