Fossil-derived energyEnergy sources have limited supply and become one of biggest global warming contributors, clean and renewable energyEnergy sources are needed. Biomass has huge potential to be used as fossil fuel substitution. Arthrospira platensis (AP) microalgae contains higher energyEnergy density compared to other biomass and can be converted into fuels through pyrolysisPyrolysis. However, tar deposit becomes a major AP conversion drawback, thereby catalysts are needed to accelerate degradation of complex molecule in pyrolysisPyrolysis process. Activated carbonCarbon (AC) is one of potential pyrolysisPyrolysis catalysts because it has excellent thermal sis cheapity and cheap. This study aims to understand the thermal behavior and determine the kinetic parameter of the AP-AC mixture with mass ratios of 10AP:7AC during the pyrolysisPyrolysis process. Thermal behavior analysis was carried out with the thermogravimetry (TG) instrument under the heating rates of 10 ℃/min. The results of the TG showed that the samples undergo three decomposition processes: moisture removal, volatile matter release or main decomposition zone, and fixed carbonCarbon recombination. The Coats-Redfern fitting method was applied to calculate the activation energyEnergy in the main decomposition zone by using ten reaction models. The result indicated that the order reaction model of F1.5 was the most proper model for decomposition of 10AP:7AC mixture. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
