In Nigeria, assemblage and discarding of residues from energy crops are increasingly becoming laborious and costly and may pose serious environmental challenges if not correctly managed. The Energy Commission of Nigeria’s long term (2016-2030) plan on the nation’s energy requirements is entirely non-fossil. This is attributable to the global decline of fossil fuel sources, soaring prices, climate crisis and the need to utilize hitherto abundant biomass resources for energy and chemical feedstocks purposes in Nigeria. In this research, an experimental study on the bio-oil generated through slow pyrolysis of Jatropha curcas L. biomass residues – Jatropha curcas L. seed shell (JSS) and Jatropha curcas L. fruit hull (JFH) were realized in a fixed bed reactor at 450 ℃ in a batch-wise step, biomass sample (1.14 mm) particle size, designed by authors. The biomass samples were subjected to pretreatment with 4% sulphuric and sodium hydroxide solutions each respectively. The Chemical compositions and functional groups available in the bio-oil of both raw and pretreated biomasses obtained at 450 ℃ were investigated by Gas Chromatography-Mass Spectrometry (GC-MS) and Fourier Transform- Infrared (FT-IR) spectroscopy analysis respectively. Scanning Electron Microscopy (SEM) was used to look into the residual biomass surface morphology of pretreated and untreated Jatropha curcas L. waste of JSS and JFH. The results acquired disclosed that the bio-oil obtained from JSS and JFH might be a principal liquid fuel starting point and chemical feedstocks.
