| Abstract | Bio-oil produced from fast pyrolysis of biomass is a potential candidate to replace conventional fossil-derived fuels. However, the fast pyrolysis derived oil generally has a high oxygen content (15-25% wt) that makes it unstable, corrosive and low in heating value. The aim of this study is to upgrade the properties of pyrolysis bio-oil by catalytic hydrodeoxygenation (HDO). To eliminate the inconsistent properties of real bio-oil for the experiment, a model bio-oil, which was a mixture of chemicals at proportions simulating bio-oil derived from eucalyptus bark reported in a previous study, was used as the sample. The experiment was conducted in a high pressure autoclave reactor operated on a batch mode at temperatures of 250-350?C, and under pressure of H2 in the presence of CoMo and NiMo catalysts. The results show that oxygen removal could be achieved and was favored by the increase in temperature. The NiMo/Al2O3 catalyst exhibited a higher activity for oxygen removal than did the CoMo/Al2O3 catalyst. Initial pressure of H2 was another factor that affects deoxygenation efficiency. The higher the initial pressure, the higher the deoxygenation efficiency. |
