【 摘 要 】

The thermal decomposition of the microalgae Spirulina platensis, synthetic wastes, and their blends under an oxidative atmosphere and their kinetic parameters were investigated using a thermogravimetric analyzer. Three stages were observed during the combustion of the blended fuels, and two distinct peaks occurred in the second stage. A kinetic analysis during combustion was studied according to the fitting method proposed by Coats-Redfern and Horowitz-Metzger. The addition of the microalgae to the synthetic waste led to an increase in the apparent activation energies in Zone I in the second stage, whereas an increasing proportion of the microalgae in the blends resulted in decreasing apparent activation energies in Zone II in the second stage.
