Deoxygenation of second generation bio-oils issued from ligno-cellulosic

Limitations of catalyst deactivation and H2 cunsumption

  • Concerned subject :

Energy and environment

  • Project summary :

The second generation bio-fuels are renewable power source that does not compete with food production. A large number of researches are launched on their production and purification processes. One of the routes to produced 2nd generation bio-fuels is the pyrolysis of ligno-cellulosic products (agricultural and wood residues, .). However, the so-produced oils contain a very high level of oxygenated compounds (up to 45 wt%), that should be removed through a hydrodeoxygenation (HDO) reaction to obtain high quality and stable diesel oils. The aim of this project is to propose a rational design of the catalyst and reaction conditions for HDO of bio-oils.

  • Principal objective aims :

Propose a rational design of the catalytic HDO step with optimization of H2 consumption and limitation of catalyst deactivation.

  • Principal expected effects :

Through a fundamental approach, we aimed at developing large knowledges in the field of synthesis and purification of bio-oils that could be used at an industrial scale.
