Abstract
NiO and CaO catalysts with different weight percentages were used as catalysts in pyrolysis to investigate the feasibility of producing biofuels from Bambusa balcooa. Non-catalytic bio-oil was dominated by aromatic (23.74 %), acids (18.07 %), and alcohols (20.02 %) while optimized catalysts NiO and CaO increased the rate of ketonization in pyrolysis of Bambusa balcooa and decreased the mass yield of acids to 6.31 % and 9.06 % respectively. The quality of bio-oil obtained from catalytic tests was compared to the non-catalytic tests in terms of its product distribution, gasoline range hydrocarbon, viscosity, pH, flash point and fire point. It was observed that 0.5 wt.% NiO and 5 wt.% CaO contained a high yield of gasoline range hydrocarbon reaching 66.75 % and 73.47 %, respectively. In addition to the chemical composition, lower viscosity of the pyrolytic oil shows 0.5 % NiO as a better catalyst in pyrolysis systems to produce enhanced quality bio-oil.
