Pyrolysis oil of wood (woody tar, WT) and a mixture of WT and vanillin (10%) was partially hydrodeoxygenated using a continuous-flow slurry-bed reactor, and the oxygen content of them was reduced to around 10%. The hydrodeoxygenated oil (HWT) was separated into light, middle distillates and bottom (>360℃). The recycle use of the bottom and catalyst recovered was also tested. The middle distillate (HWT-MD, 240〜360℃) was co-hydrotreated with petroleum LGO using a continuous-flow fixed bed reactor. Since the nitrogen content of HWT-MD(1700ppm) was much higher than that of LGO (40ppm), the HDS reaction was inhibited significantly by the addition of HWT-MD.
