ETHANOL DEHYDRATION CATALYST FOR ENERGY SAVING AND METHOD OF MANUFACTURING ETHYLENE USING SAME

摘要

Provided are an ethanol dehydration catalyst having a high ethylene yield even at a low temperature region, as an ethanol dehydration catalyst for converting a feedstock including anhydrous ethanol or hydrous ethanol to ethylene, and a method of preparing ethylene by using the same. In the ethanol dehydration catalyst for converting a feedstock including anhydrous ethanol or hydrous ethanol to ethylene of the present invention, the catalyst includes 0.1 wt% to 0.5 wt% of lanthanum (La) or 0.05 wt% to 1 wt% of gallium (Ga) in ZSM-5.
