The dwindling natural resources and governmental constraints on greenhouse gas emissions have made renewable fuel production from biomass a viable supply chain option.  Generating liquid fuels through flash pyrolysis of woody biomass and the subsequent upgrading has been identified as one of the feasible ways to achieve this goal.  The overall aim is to produce a drop-in liquid fuel that has similar properties as conventional gasoline, diesel or jet fuel cuts through thermochemical and catalytic means. Bio oils are complex mixtures of many organic molecules with varying molecular weights, physical properties and functional groups. As such we need to have a good understating of the distribution of oxygenates after distillation into different cuts. These reactive and corrosive components can cause complication during downstream processing of bio-oils. In the last two years under the patronage of the US-DOE, we have developed a suite of standardized methods to analyze and describe bio-oils. We have applied these methods to understand the distribution of oxygenates when hydrotreated bio-oils are fractionated into gasoline, diesel or jet fuel cuts through distillation. The methods developed, lessons learnt, and application of these methods to different oils will be discussed.        <br/>
