The hydrodenitrogenation of the bio-oil produced from activated sludge was performed at 250-370℃ and 2.0MPa over the sulfided P-added NiMo/Al_2O_3 catalysts. The bio-oil was prepared from the pyrolysis of dried activated sludge using steam, nitrogen and air fed to a fluidized bed reactor at 500℃ and residence time of 1s. The reaction in the present work was carried out in a continuous flow fixed bed reactor with LHSV=5-10h^<-1>. The xylene-soluble (partially dissolved) bio-oil (BO/Xy) and totally soluble bio-oil in ethanol (BO/EtOH, ratio=1:4) and in diethylene glycol (BO/DEG, ratio=1:8) were prepared as the reaction feed. The nitrogen containing compounds were totally denitrogenated throughout the 6h reaction period during the hydrotreatment of BO/Xy containing 0.5% nitrogen compounds at 367℃. Indole, pyridine and other compounds were denitrogenated.
