Abstract
This study aims to analyze the thermal characteristics of Tetraselmis chuii (T.Chuii) microalgae in the presence of TiO2 (Titanium dioxide). The experiment was carried out on thermal analyzer equipment under inert condition. The blended sample has a mass ratio of microalgae and TiO2 that was 10:0.03 (wt%). The results of the thermal analysis show that the addition of TiO2 can change the temperature characteristics during the reaction process. The Coats-Redfern method is applied to calculate activation energy (Ea) resulted in the value of the blended fuel in the second stage that was 56.9 kJ/mol lower than that of pure microalgae that was 70.68 kJ/mol and conversely in the third stage the value of activation energy for blended fuel was 264.57 kJ/mol higher than pure microalgae that was 223.25 kJ/mol. Overall results pointed out that TiO2 had a significant impact on the thermal characteristic of Tetraselmis chuii during the pyrolysis process.
