- Biomass is a renewable resource utilized to produce energy, fuels and chemicals. In this study, 25 bioresidues were selected and the physical, chemical, thermal and elemental analyses of the residues were studied as per standard methods. The bioresidues were pyrolyzed at 450°C in a fixed bed reactor to produce biooil. Among the residues, paper (pinfed computer) and Parthenium produced maximum (45%) and minimum biooil (6.33%), respectively. Arecanut stalk, redgram stalk, rice husk, wheat husk, maize cob, coir pith, Cumbu Napier grass Co5, Prosopis wood and paper resulted in a better biooil yield. Models were developed to predict the effect of constituents of bioresidues on the yield of biooil. The volatile matter and cellulose had significant effect on biooil yield. Biooil thus obtained can be used as fuel that may replace considerable fossil fuels.
