Abstract: A selective pyrolysis process for the production of bio-oils enriched in pyrolytic sugars and phenols and conversion of these compounds into second generation bio-fuels is disclosed herein. One embodiment of the process comprises pre-treating a biomass with superheated steam or gases in a selected range of temperatures, followed by fast pyrolysis using synthesis gas as a carrier, and a two-step condensation operation. The aqueous phase from the second condenser can then be reformed to produce hydrogen or can be gasified together with the charcoal to produce syngas.
