Abstract
Analysis of two kinds of bio-oil, woody tar and pyrolyzed Jatropha residue was carried out and effect of the composition of bio-oil on its hydrodeoxygenation was investigated. The nitrogen content of pyrolyzed Jatropha residue was 2.5% and it was much higher than that of woody tar (0.1%). The nitrogen conmpounds contained in pyrolyzed Jatropha residue were basic nitrogen compounds such as pyrazines and pyridines and acid amides derived from fatty acids. Distillated woody tar gave a product rich in monocyclic aromatic hydrocarbons in the hydrodeoxygenation over a CoMo sulfide catalyst.
