Decomposition Characteristics and Kinetics of Microalgae in N₂ and CO₂ Atmospheres by a Thermogravimetry

Table 2

Results from thermogravimetric analysis for Chlorella vulgaris in different atmospheres with the heating rate of 10°C/min.

Atmosphere	Heating rate (°C/min)	(°C)	DTG1 (% min^−1)	(°C)	DTG2 (% min^−1)	(% min^−1)	Residual mass (%)
CO2	10	323.8	−3.54	901.1	−3.26	−3.54	16.86
N2	10	322	−3.94	—	—	−3.94	23.12

Note: is the temperatures for the first weight losses reaction peak; DTG₁ is the reaction rate for the first weight losses reaction peaks; is the temperatures for the second weight losses reaction peak; DTG₂ is the reaction rate for the second weight losses reaction peak; is the maximum reaction rate.
