Manuscript-Ethanol dehydration to diethyl ether over CuSUZ-4 zeolite and FeSUZ-4 zeolite.pdf

This study investigates the catalytic dehydration of ethanol to diethyl ether using SUZ-4 zeolite modified with 2.5%, 5.0%, 7.5%, and 10.0% copper and iron to enhance catalytic efficiency. The catalysts were characterized using XRD (to analyze crystallinity), SEM (to observe morphology), FTIR (to identify functional groups), BET (to determine surface area and pore structure), and TPD-NH3 (to evaluate acidity). The effects of reaction temperatures (160°C, 190°C, 220°C, and 250°C) were examined. Results indicate that the 5.0% Fe/SUZ-4 catalyst exhibited the highest diethyl ether formation at 220°C, with ethanol conversion rates ranging from 27.34% to 60.24%.
