Pyrolysis is that the thermal decomposition of biomass into liquids, gases, and char (solid residue) within the absence of oxygen. Pyrolytic products are also used as fuels, with or without prior upgrading, or they could be utilized as feedstock for chemical or material industries. Bio-oil was produced from sawdust of Gmelina arborea, and Cordia millenii in an exceedingly fixed-bed slow pyrolysis reactor under two temperature regimes (500°C and 600°C). The bio-oil produced was characterized by proximate analysis, CHN-elemental analysis, pH in solution, bomb calorimetric for higher heating value. The results of the proximate analysis revealed that the fixed carbon content) within the bio-oil samples strongly trusted the intensity of the thermal treatment (i.e. higher temperatures and longer residence times within the pyrolysis process). the actual yield in fixed carbon values ranged from 25.00 to 61.67% recorded in Gmelina arborea and 23.33 to 58.33, recorded for Cordia milenii. The results of the study shows that there is no significant difference between the chosen sawmill wood residues used at different temperature range. High percentage ash content of 40.00 it had been recorded in Gmelina arborea at lower temperature of 500°C, while Cordia milenii has the lower mean percentage ash content of 31.67% at lower temperature of 500°C and least percentage average of 21.67% at higher temperature of 600°C. The norm for percentage of volatile matter ranged from 20.00 to 45.00 try to 13.33 to 35.00% which indicated that Cordia milenii has higher mean percentage volatile matter at 500°C while Gmelina arborea at 600°C has the tiniest amount mean percentage volatile matter. The results of the calorific value revealed the upper and lower mean for the heating value of the bio-oil which ranged from 23083.22 to 26725.74, and 20305.98 to 25637.17 (Kj/kg) for Cordia milenii and Gmelina arborea at 500°C and 600°C respectively. The ultimate analysis showed the variations within the basic composition of the chosen sawmill wood residues used. The FT-IR spectra of bio-oil samples obtained from different temperatures exhibited identical peaks but these spectra differed within the relative intensity of some bands.
