Abstract
Energy demand is increasing due to rapid growth in population and leads to
depletion of fossil fuels. To prevent the energy crisis, this study explores fast pyrolysis
of Jackfruit peel into bio-oil in a drop-type fixed bed reactor. This is because, the
biomass considered very effective renewable resources compared to conventional fossil
fuels where it can be used for energy production which potentially sustainable and
reduce environmental pollution. Fast pyrolysis serves as promising techniques to
dispose of agriculture waste and to get bio-oil, bio-char and syngas simultaneously. The
experiment was carried out at different reaction temperature (350-650 oC), particle size
(0.25-2 mm) and nitrogen flow rate (200-400 mL/min). The highest bio-oil yield (57.86
wt%) was obtained at 550 oC with Jackfruit Peel (JFP) waste size of 0.5-1 mm and 200
ml/min of nitrogen gas flow rate. Preliminary experiment was conducted using
thermogravimetric analyzer (TGA) to determine the proximate analysis of JFP. Then,
elemental composition and higher heating value of the feedstock and bio-oil (550 oC)
were determined and compared. Additionally, the FTIR analysis and GC-MS analysis
were carried out on bio-oil to investigate the functional group and chemical composition
of bio-oil respectively. The chemical characterization of bio-oil results provide some
promising insight into the application of bio-oil in chemical plant, which could be
useful as a chemical feedstock and used as combustion fuels for electricity.
