Descrição: dc.descriptionIsoconversional kinetic analysis is applied to thermogravimetry data on vaporization of n-decane and dimethyl sulfoxide from alumina nanopores and bulk. For bulk vaporization, the isoconversional activation energy is independent of conversion and equal to the enthalpy of vaporization. For vaporization from nanopores, the isoconversional activation energy varies stronglywith conversion, passing through aminimumat midrange conversions. This behavior is shown to be consistent with the successive transition of the rate control fromthe Kelvin effect to Knudsen diffusion, and eventually to surface diffusion. All three phenomena are demonstrated to have their specific activation energies. It has been determined that the deceleration of vaporization from nanopores is due to a dramatic decrease in the value of the preexponential factor. The decrease is linked to the high frequency of collisions with the pore walls and to a possibility of adsorption on the walls. (C) 2020 Elsevier B.V. All rights reserved.-
