► The low-boiling fraction of rice husk pyrolytic bio-oil was used for hydrogen production. ► Hydrogen content of the gas products can be as high as 65vol.%. ► Reaction temperature is about 400K lower than that applied in steam Reforming. ► Aqueous-phase reforming is a promising method to utilize organics in low-boiling fraction of the bio-oil to produce hydrogen. Aqueous-phase reforming (APR) of the low-boiling fraction (LBF) of bio-oil from rice husk pyrolysis was investigated over Pt/Al2O3 for hydrogen production. The influence of reaction temperature (503–563K), reaction time (1–4h), different load of organics in water (3–12wt.%) and catalyst amounts (0.25–1g) were studied. The hydrogen content of the gas products reached 65vol.% at 533K for 4h with a feedstock of 9.6g LBF and 30mL water in the presence of 0.5g of 2wt.% Pt/Al2O3. APR is a promising method to make use of the organics in LBF of bio-oil to produce hydrogen.
