Pyrolysis kinetic, thermodynamic and product analysis of different leguminous biomasses by Kissinger-Akahira-Sunose and pyrolysis-gas chromatography-mass spectrometry

To ascertain the potential of various leguminous biomass such as L. leucocephala, C. proliferus, P. alba and S. sesban, both energetic a source high added value products, pyrolytic behaviour was studied at different heating rates by using analytical method thermogravimetric (TG), isoconversional Kissinger-Akahira-Sunose (KAS), determination some thermodynamic parameters pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS). It concluded that leucocephala or proliferus are more suitable for pyrolysis since less energy is required to degrade them, evident in final stages degradation which sesban present very activation energies calculated KAS. All produced volatile compounds with phenol content peak maximum hemicellulose, most heavy derivates derived from lignin, ferulaldehyde methoxyeugenol, because sufficient has not yet been provided break down structure. At this it can see furans saccharides case higher C5 its composition. A wide range were detected cellulose, produce short-chain give rise bio-oils whereas, especially alba, addition, quantity levoglucosan d-allose (4.73% 13.94%, respectively).
