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.

A new approach to address the problems of the large land area required for cultivation, culture contamination and the difficult and costly dewatering of the harvested cells in large-scale algal biofuel projects is under development at Iowa State University.
