Thermogravimetric analysis has established kinetics for the devolatilization of bio sanitary waste as possible sources for alternative fuels. In this study, the thermal degradation of materials was carried out at different heating rates: 5, 15, 30 °C/min with dynamic ramps and isothermal periods in the thermogravimetric analyzer. The data from the mass loss at different times and temperatures, the conversion of the thermal decomposition reaction was calculated, this value was used in three mathematical models that will predict the kinetic parameters such as activation energy, pre-exponential factor, and order of the reaction. A better fit model is proposed by minimizing the error between the calculated thermal degradation rate and the experimental one. It is concluded that the best kinetic model for contaminated clothes and gloves considered the Arrhenius equation and reaction order two and includes reference temperatures of 450 and 367 °C for each material. The activation energy values for contaminated gowns and gloves are 553.62 and 154.06 kJ/mol, respectively. It is established that by achieving a conversion of 0.98 in the thermal degradation of these materials, they can be converted into the material of interest as alternative fuels.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
