Abstract
Energy is essential for improving human living conditions, but, at the same time it is necessary to provide not only energy, but it clean and renewable. One way to ensure the generation of clean and renewable energy is through biomass gasification process. However, there is still a lack of data in the literature for different biomass gasification process. This work performs thermal analysis in the microalga, Chlorella sp., in order to verify the behavior and characteristics of this biomass for application in energy production through gasification process. Thermal analysis of TGA/DTG and calorimetry were performed. It was possible to define two stages of thermal degradation (30 °C - 500 °C and > 500 °C) attributed to the volatilization of different compounds. The peak of mass loss rate occurs at approximately 560 °C, which must be related to the thermal degradation of char formed by biomass. It is noticed a great ash presence at the end of the temperature of 800 °C, which can be a harmful factor for its application in the gasification. Finally, the calorific value of the microalga, presenting a value close to the other feedstock.
