Bio-oil derived from pyrolysis of biomass has been expected as alternative fuel sources replacing the conventional fossil fuels. However, the direct application of bio-oil as transport fuels without prior treatment is prohibited due to its high content of oxygenated compounds resulting to undesired properties. This research aimed to prepare and upgrade the bio-oil obtained from pyrolysis of Leucaena leucocephala via deoxygenation catalyzed by platinum supported on alumina (Pt/Al2O3). The bio-oil used for catalytic deoxygenation was the mixture of heavy bio-oil, collected from solvent leaching of char and residue inside the pyrolysis reactor, and light bio-oil, obtained from the condensation of pyrolysis vapor, at 1/1 (w/w). The oxygen and water contents in this bio-oil were ca. 37% and 55% wt; respectively. For deoxygenation catalyzed by 10% wt of Pt/Al2O3 under nitrogen atmosphere for 1 h, the results indicated that the increase in the reaction temperature to 420°C gave the highest %oxygen removal as ca. 56%. The composition of deoxygenated bio-oil analyzed by using GC-MS also indicated the conversion of oxygenated complexes as phenol and its derivatives.
