Abstract
Terminalia ivorensis wood sawdust (TIWS) was pyrolyzed under nitrogen atmosphere. Pyrolysis temperature influence on the product yields and the fuel properties of the yields were investigated between heating range of 400 – 700 °C. The peak condition for bio-oil yield from pyrolysis was determined. The proximate and elemental analysis of the raw sample and bio-char yields at different temperatures were carried out. Gas chromatography mass spectrometry (GCMS) analysis of the bio-oil obtained at the optimum condition was also done. The optimum yield of bio-oil (50%) was obtained at a pyrolysis temperature of 500 °C. The proximate and elemental analysis results of the raw sample showed volatile matter and carbon were 75.22 and 49.80%, respectively with a Higher Heating Value (HHV) of 19.71 MJ/kg while those of bio-char showed average values of 14.38 and 75.45%, with an average HHV of 26.14 MJ/kg. GCMS analysis showed that dominant hydrocarbon mixtures in the bio-oil were palmitic acid (16.0%), cis-1, 9-hexadecadiene (15.0%), cis-10-pentadecen-1-ol (14.0%), 9-octadecenal (12.0%), trans-2-octadecadecen-1-ol (12.0%), oleic acid (7.3%), myristic acid (4.0%) and stearic acid (3.0%). These findings revealed considerable amounts of hydrocarbons, fatty acids, alcohols, esters, ethers, ketones, furan and phenolic compounds in bio-oil derived from pyrolysis of TIWS, making it a potential source of bio-fuel and chemical compounds, and that the derived bio-chars have sufficient heating values for solid fuel applications.
