Kinetic Study of Thermal Degradation Mechanisms of Oleaginous Biomass

Short Introductive summary

The soil’s salinity has been increasing in the last years, which causes a degradation of these and lowers the crop yield. To avoid the competition of productive land to produce energy vectors, it is proposed to use plants that grow in salty conditions as a source of energy. In this context, the production of biofuels from the thermochemical conversion, specifically liquefaction, of halophyte seeds is proposed. Determining kinetic parameters is crucial for elucidating the mechanisms of biomass liquefaction. Therefore, the activation energy necessary to trigger the liquefaction reaction of the raw material will be determined through the kinetic study of the thermal degradation of different biomasses. These parameters play a crucial role in determining energy efficiency. Therefore, the aim of this research is to optimize them by studying the thermal degradation of biomasses. For that purpose, the different thermal degradation mechanisms of oleaginous seeds were studied using thermogravimetric analysis. The calculations of the kinetic parameters of the reaction mechanisms were performed through the Kissinger and isoconversional methods.
