Abstract

Wastewater-fed microalgal biomass has attracted a considerable interest for biofuel production via pyrolysis in recent years. In this study, thermal degradation behavior and pyrolysis kinetic parameters have been investigated by non-isothermal thermogravimetric analysis. Analysis of the reactive phase showed two partially overlapping devolatilization stages, with degradation peaks at 540–570 K, accompanied by a shoulder at around 590–615 K, and 735–785 K, respectively. Model-free kinetic methods showed a large variation in the activation energy with the conversion degree, suggesting a multi-step reaction scheme. Consequently, a parallel order-based reaction model of three pseudo-components (proteins, carbohydrates and lipids) was applied, showing a good agreement with the experimental data. Based on this approach, the average activation energies were 143, 166 and 61 kJ·mol−1 for proteins, carbohydrates and lipids, respectively, while the average orders of reaction were 2.3, 1.6 and 0.6.
