Bio-oils are produced from various biomass sources through processes such as pyrolysis and hydrothermal treatment. While conventional oils from fossil energy sources contain less than 0.1 wt% oxygen, the oxygen content of bio-oils can reach as high as 50 wt% causing several undesired properties such as high viscosity, instability and low energy content. The oxygen can be removed partly or totally by hydrodeoxygenation (HDO). Process characteristics of the HDO of wood-based bio-oils and HDO studies carried out with bio-oil model components are presented.
