Characterization of lignocellulose biomass based on proximate, ultimate, structural composition, and thermal analysis

This research deals with the determination of physicochemical and thermal properties of biomass samples to enhance pyrolysis yields. Proximate, ultimate, structural composition, trace elements, and thermal analyses were conducted using fifteen lignocellulose biomass samples obtained in Ajase market, Ajasse Ipo, Kwara State, Nigeria, and Omu-Aran, Kwara State, Nigeria respectively. Results obtained from the ultimate analysis showed that Oxygen, carbon, and sulfur show minimum, medium, and peak effects on the HHV and LHV of biomass, while Nitrogen and Hydrogen do not positively influence the HHV and LHV. Also, Also, for the proximate and structural composition analysis, it was observed that fixed carbon, volatile lignin, ether extracts, cellulose, and hemicellulose positively enhanced the desirability of the biomass by increasing its heating value, while moisture, ash, and corrosiveness reduced pyrolysis yield because they reduced the HHV and LHV of lignocellulose biomass.
