Intrinsic Kinetics of Ethanol Dehydration Over Lewis Acidic Ordered Mesoporous Silicate, Zr-KIT-6

Lewis acidic Zr-KIT-6 catalyst was tested for ethanol dehydration. Under the reaction conditions studied (T = 300–380 °C, P = 1 atm, P ethanol = 5 % in N 2 ), Zr-KIT-6 materials showed high ethylene selectivity (~80 %) with stable activity (60 h). The activation energy for ethanol dehydration to et...

Zusammenfassung:	Lewis acidic Zr-KIT-6 catalyst was tested for ethanol dehydration. Under the reaction conditions studied (T = 300–380 °C, P = 1 atm, P ethanol = 5 % in N 2 ), Zr-KIT-6 materials showed high ethylene selectivity (~80 %) with stable activity (60 h). The activation energy for ethanol dehydration to ethylene, estimated from intrinsic rate constants normalized with respect to the Lewis acid sites, was approximately 79 ± 1 kJ/mol.
