Electrocatalytic hydrogenation and hydrodeoxygenation of oxygenated and unsaturated organic compounds

A process and related electrode composition are disclosed for the electrocatalytic hydrogenation and/or hydrodeoxygenation of biomass-derived bio-oil components by the production of hydrogen atoms on a catalyst surface followed by the reaction of the hydrogen atoms with the organic compounds in bio-oil. The catalyst is a metal supported on a monolithic high surface area material such as activated carbon cloth. Electrocatalytic hydrogenation and/or hydrodeoxygenation stabilizes the bio-oil under mild conditions to reduce coke formation and catalyst deactivation. The process converts oxygen-containing functionalities and unsaturated bonds into chemically reduced forms with an increased hydrogen content. The process is operated at mild conditions, which enables it to be a good means for stabilizing bio-oil to a form that can be stored and transported using metal containers and pipes.
