title: Pyrolytic and kinetic analysis of two coastal plant species: Artemisia annua and Chenopodium glaucum.
abstract: The large amount of coastal plant species available makes them ideal candidates for energy production. In this study, thermogravimetric analysis was used to evaluate the fuel properties of two coastal plant species, and the distributed activation energy model (DAEM) was employed in kinetic analysis. The major mass loss due to devolatilization started at 154 and 162°C at the heating rate of 10°C min(-1) for Artemisia annua and Chenopodium glaucum, respectively. The results showed that the average activation energies of Artemisia annua and Chenopodium glaucum were 169.69 and 170.48 kJ mol(-1), respectively. Furthermore, the activation energy changed while the conversion rate increased, and the frequency factor k 0 decreased greatly while the activation energy decreased. The results also indicated that the devolatilization of the two coastal plant species underwent a set of first-order reactions and could be expressed by the DAEM. Additionally, a simplified mathematical model was proposed to facilitate the prediction of devolatilization curves.
