The processes of dehydration of C2-C4 alcohol and dealkylation of alkylbenzenes over H-β and WO3/ZrO2
catalysts were studied using the method of temperature programmed reaction. On the basis of TPR spec-
tra of olefin formation the linear relationships between the temperatures of maximal rates of these reac-
tions and proton affinities of alcohol and alkylbenzene molecules was found.
