Electrochemical Processes for Bio-Oil Deoxygenation
. by Martin Bergstedt
Biomass fast pyrolysis yields oxygen rich (hydrogen deficient) hydrocarbons of inferior fuel quality. They contain upwards of 40 dry-weight % oxygen, whereas petroleum contains around 1%, so these bio-oils must be upgraded to be rightfully considered a replacement for liquid fossil fuels. Jack Ferrell of NREL's National bioenergy Center spoke at the Spring Meeting about their program to develop electrochemical hydrodeoxygenation processes.
