The aim was to recycle greenhouse gas carbon dioxide for mitigating emissions, to evaluate the thermal behavior, reactivity, conversion and product composition in terms of structural/chemical characteristics of the fuels, and to provide accurate kinetic parameters useful in the scaling-up of the process. The experiments were conducted in a thermogravimetric system, coupled with a mass spectrometer. Both models accurately represented the pyrolysis process by three first-order reactions with deviation values ranging from 1.6% to 2.4%. For the gasification process, one pseudo-component described the process successfully, with deviation values of 2.3-5%. The IPR model provided a superior fit. Activation energy values estimated by the DAEM model were higher than those predicted by the IPR model.
