Kinetic analysis and pyrolysis behavior of pine needles by TG-FTIR and Py-GC/MS

The pyrolysis performances and reaction kinetics of pine needles (PN) were investigated by integrating thermogravimetric analysis, Fourier transform infrared spectroscopy, pyrolysis-gas chromatography/mass spectrometry. average activation energy PN was estimated to be 183.2 kJ/mol Kissinger Akahira Sunose (KAS) 183.8 Flynn Wall Ozawa (FWO), respectively at heating rates 10, 20, 40 °C/min. found more efficient the lower rates, while increased promoted reaction. Using King-Kai (K-K) method, energies hemicellulose, cellulose, lignin calculated 156, 165, 172 kJ/mol, respectively. descending order evolving gases functional groups from CO2, C=C, C=O, H2O, CH4, CO. main pyrolytic by-products identified hydrocarbons, phenols, alcohols, ketones, aldehydes. determination kinetic parameters provides fundamental information for predicting which chemical reactions occur. This study demonstrates potential as a suitable source bioenergy.
