Novel Electro-Deoxygenation Process for Bio-oil Upgrading
Biomass is a potential source of renewable fuel. Bio-oil produced by fast pyrolysis is a prospective option to replace fossil fuels for transportation. However, bio-oil needs to be upgraded to remove its high oxygen and water content, and acidity to produce useful fuels. The upgrading of bio-oil is generally accomplished by hydrodeoxygenation (HDO) using hydrogen. The instability of bio-oil poses a major challenge in transportation to central upgrading facility. An electro-deoxygenation (EDOx) process was evaluated to fully or partially deoxygenate bio-oil using solid oxide electrolysis process. This device uses an oxygen ion conducting membrane which under an applied electric potential removes oxygen in the form of an ion and transports it to the opposite side of the membrane where it is released as oxygen molecule. When water is present in the bio-oil vapor, the process generates in situ hydrogen to facilitate deoxygenation over the electrode that functions as catalyst.
