Pyrolysis of micro- and macroalgae in thermobalance coupled with mass spectrometer

Popis výsledku v původním jazyce

Due to the constant increase of energy demand, new ecological sources of energy are being sought. One of the promising directions is the use of algae biomass from special cultivation or biomass floating on the sea. In order to determine the potential of algae for thermal decomposition, the pyrolysis study in thermobalance coupled with mass spectrometer was carried out at heating rates of 5, 10, 20 °C/min, in the temperature range of 30–900 °C Three types of algae: macroalgae Cladophora glomerata and Fucus vesiculosus, and microalgae Chlorella pyrenoidesa were used in this research. During the deconvolution of the derivative of the thermogravimetric curves, three peaks were assigned to the decomposition of carbohydrates, proteins and lipids. The isoconversional kinetic model used indicated that the pyrolysis process occurred in several reactions. The proposed kinetic model consists of three nth order independent parallel reactions of pseudo-components. The calculated activation energy ranged from 39 to 266 kJ/mol for carbohydrates, 177–181 kJ/mol for proteins, and 110–229 kJ/mol for lipids. The obtained results could be used in the design of 3rd generation biorefineries.
