Abstract

The pyrolysis characteristic of the Tetraselmis chuii microalgae has been investigated through a thermogravimetric device. This experiment was carried out on 10 °C/min heating rate with 50 ml/min continuous nitrogen flow rate and 25-900°C temperature range. The results verified that four stages degradation processes were encountered during Tetraselmis chuii pyrolysis. During the pyrolysis process, the active region of volatile release occurs in two different stages. Degradation of carbohydrates and proteins take place in stage 2, whereas lipids are decomposed in stage 3. Analysis of kinetics parameters includes Ea (activation energy), A (pre-exponential factor), and n (reaction order) yielded the respective values of 70.68 kJ/mol, 1.72/minute, 1.22 and 223.25 kJ/mol, 11.43/minute, 2.44.
