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 methan`ol could not be safely ruled out. The activation energy of 114.7 kJ/mol for methanol dehydration on gamma-Al2O3 was obtained from the kinetic analysis.
