Abstract In this research, de-oiled biomass such as Chlorella vulgaris (CV), and Spirulina Platensis (SP) was utilized to study its kinetics of pyrolysis behavior. The pyrolysis conditions studied were set at the different heating rate at 10 °C, 20 °C, 30 °C and 40 °C/min under inert atmosphere in the temperature range of 30–1000 °C. Iso-conversional method was adopted to calculate the apparent kinetic energy, and it was found that the activation energy of the CV is in the range of 8.7–20.9 kJ/mol., which is less than the SP range of 16.4–157.7 kJ/mol. The kinetics data reveals the CV is found suitable for fuel production. The average regression coefficient value of the experiments was obtained as R2 0.96. The major products found were H2O, CO2, and CH4, which shows the potential for producing syngas, and biofuel from the microalgae.
