With the depleting oil reserves and the increasing demand worldwide for the transportation of fuels and chemicals, the need for an alternative fuel source is becoming increasingly apparent. Bio-oil is produced through fast pyrolysis or hydrothermal liquefaction routes. But the produced bio-oil has high oxygen content, leading to a low heating value and lower stability over the time. Hence, methods to upgrade bio-oil to make it more closely resemble the crude oil are urgently sought. Catalytic hydro-treatment is one of the most promising technologies for Hydrothermal Liquefaction (HTL) and upgrading biofuel. In the current study, HTL biooil produced from Chlorella microalgae slurry in a continuous flow reactor was hydro-treated with bio-Pd/C. Bio-Pd/C uses metallic NP-decorated whole bacterial cells as chemical catalysts and the activity of the Bio-Pd/C catalyst was evaluated against commercial Pd/C. The upgrading potential of the bio-Pd/C was investigated under three variables: Time, temperature and oil to catalyst ratio in a stirred reactor. Both catalysts Pd/C and bio-Pd/C showed similar activity under similar upgrading condition. Oxygen and nitrogen content were reduced by 65% and 35%, respectively, at 325Ã?Â°C in 4 h reaction time. Further analysis of upgraded oil by GC-MS, Sim- Dist, and elemental analysis attributed to the improvement in the fuel properties of bio-oil. Catalyst analysis with ICP-MS, TGA and elemental analyzer attributed that the biomass from bio-Pd/C contributed to bio-oil yield.
