Supporting Information: Activation Energy of Temperature Programmed Desorption Calculated Using Least-SquaresMethod for Benzene, Thiophene and Octane on NaY

Temperature programmed desorption (TPD) spectra of benzene, thiophene, and octane on NaYat different heating rates were measured and the order of desorption for the TPD was estimated by the shape of TPD spectra and their characteristic differential curves. A new TPD model using least-squares method was proposed, by which the desorption activation energies, as well as the kinetic parameters of the systems, could be calculated. Based on these experimental spectra, desorption activation energies of benzene, thiophene, and octane on NaY were calculated by a traditional model, the least-squares method, and the first differential curve of the TPD model. The results show that the desorption activation energies at different heating rates calculated by the least-squares method agree well with each other.
