Bio Oil

The market demand of bio-fuel is 11,8 billion litters based on recent reported data. Hence, with the high demand of bio-fuel, the bio-fuel production utilizing rice husk can be one of the solutions. Beside, bio-oil can be produced by pyrolysis process utilizing rice husk as the feedstock. In this research, the optimization condition in producing bio-oil from rice husk by catalytic pyrolysis process was studied. The effect of catalyst type (H-β, H-Y, HZSM-5), catalyst loading (1wt%, 5wt%, 12wt%), temperature (400-500°C) and flow rate (60-100ml/min) were investigated through repetitive experiments using L9 Taguchi Orthogonal Array. The highest liquid yield of 38wt% was obtained at the optimum conditions with temperature of 500°C with nitrogen flow rate of 60ml/min and 12wt% of H-ZSM-5.

Groundnut Shell

Pyrolysis process in a fixed bed reactor was performed to derive pyrolytic oil from groundnut shell. Experiments were conducted with different operating parameters to establish optimum conditions with respect to maximum pyrolytic oil yield. Pyrolysis process was carried out without catalyst (thermal pyrolysis) and with catalyst (catalytic pyrolysis). The Kaolin is used as a catalyst for this study. The maximum pyrolytic oil yield (39%wt) was obtained at 450°C temperature for 1.18- 2.36 mm of particle size and heating rate of 60°C/min. The properties of pyrolytic oil obtained by thermal and catalytic pyrolysis were characterized through Fourier Transform Infrared Spectroscopy (FT-IR) and Gas Chromatography-Mass Spectrometry (GC-MS) techniques to identify the functional groups and chemical components present in the pyrolytic oil. The study found that catalytic pyrolysis produce more pyrolytic oil yield and improve the pH value, viscosity and calorific value of the pyrolytic oil as compared to thermal pyrolysis.
