The Gibbs energy change, isosteric heat and entropy of CO 2 , sorbed at intervals of approximately 30 K between 273 and 393 K in X-type zeolites exchanged with Zn2+ and Cu2+ cations to different degrees, are investigated. The best fit of sorption isotherm data is obtained with the Langmuir model. Th
