Abstract: By using SETARAM heat-flow calorimeter the differential heats of adsorption for cyclohexene and 2-methyl-pentene-1 on NaY, CaY, R_EY and HY zeolites at ambient temperature have been measured. By means of Benson's method for the estimation of thermochemical data, the heats of adsorption for tertiary and secondary carbonium ions have been obtained. According to the differnce between heats of adsorption for cyclohexene and 2-methyl-pentene-1 at the same adsorption amounts the adsorption mechanism for cyclohexene and 2-methyl-pentene-1 on the zeolites has been discussed.
