The thermal decomposition of the microalgae 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.
使用热重分析仪研究了微藻合成废物及其混合物在氧化气氛下的热分解及其动力学参数。在混合燃料燃烧过程中观察到三个阶段，并且在第二阶段出现了两个明显的峰。根据Coats-Redfern和Horowitz-Metzger提出的拟合方法研究了燃烧过程中的动力学分析。将微藻添加到合成废物中导致第二阶段I区的表观活化能增加，而混合物中微藻比例的增加导致第二阶段II区的表观活化能降低。
