Abstract

The kinetic data of about 150 points for methanol dehydration were obtained at the temperature of 240~270^oC, the GHSV of 25,000~120,000 (mL/g_cat./h) and under atmospheric pressure. The data were fitted into six plausible equations. The kinetic equation derived from the molecular adsorption of methanol on two sites fit the kinetic data best, however, that from the dissociative adsorption of methanol could not be safely ruled out. The activation energy of 114.7 kJ/mol for methanol dehydration on γ-Al ₂O₃ was obtained from the kinetic analysis.
