Abstract
In this study, the physicochemical properties such as proximate, ultimate analysis and heating value of five wood species sawdust (WSD) samples have been determined. The Higher Heating Values (HHVs) of the samples were estimated as functions of fixed carbon (FC) and volatile matter (VM), and were also calculated from an elemental composition-based correlation equation. Results showed the ranges of VM and FC were 74.95 – 75.74% and 14.25 – 14.80%, respectively. The High Heating Values (HHV) of Iroko, West African Entada, Ebony, African cam and Rough chaff, according to ultimate analysis-based correlation equation, were found to be 18.85, 18.77, 18.75, 18.55 and 18.52 MJ kg-1, respectively while according to proximate analysis-based correlation equation, were 18.41, 18.53, 18.43, 18.50 and 18.14 MJ kg-1. The high percentage of VM and the value range of FC resulted in appreciable HHVs for the samples. It can be concluded that woody biomass residues are good sources of bio-fuels for sustainable development.
