Improved Process for Preparing Bio-oils from Biomass

The invention described herein provides an improved process for preparing bio- oils from biomass using pyrolysis. The process can comprise a step of acid pre-treatment of biomass prior to microwave assisted pyrolysis, and comprise a reformation step prior to condensation. The process of the invention can be used to produce simpler higher quality bio-oil compositions from a given biomass input, and with greater liquid percent yield relative to starting biomass solid weight. Resultant bio-oil output can comprise a water- soluble fraction and insoluble oil fraction, the components of which can be further separated to provide various useful compounds.
