“…Another form of upgrading that produces a stable bio-oil uses electricity to remove oxygen. A few studies (Lessard, 2014;Li et al, 2014;Moutet, 1992;Wang, Lee, Olarte, & Zacher, 2016;Zhang, Zhang, & Zhong, 2018) have explored the use of electrocatalytic hydrogenation (ECH) as an approach to stabilize and upgrade biomass pyrolysis liquids to form chemicals and fuels. Herein, we review a fast pyrolysis process with electrochemical deoxygenation, wherein the biomass undergoes fast pyrolysis forming char and bio-vapor, which are separated via a cyclone to isolate the vapor and pass it through a solid oxide membrane reactor (EDOx; Milobar, Hartvigsen, & Elangovan, 2015).…”
