Producing an infrastructure-ready fuel from biomass also requires a better understanding of the chemical constituents of the gasoline, diesel and jet fuel fractions of the biofuel product. Determining the distribution of heteroatoms, especially O and S, impacts the acceptability of a distillate fraction within specific fuel specifications. These reactive and corrosive components can cause complication during downstream processing of bio-oils. We have developed a suite of standardized methods to analyze and describe bio-oils. We refined the analysis of distillates from pyrolysis oil by controlling the source and processing of hydroprocessed bio-oils with two oxygen contents. The upgraded bio-oils were subsequently distilled into five fractions. Analytical techniques such as elemental analysis, density, viscosity, simulated distillation (ASTM D2887), 13C NMR, PIANO and HPLC measurement were used and results will be presented. Specific fractions were found to satisfy boiling point requirements but functional group characterization will likely preclude their direct use as fuel. The methods developed, lessons learnt, and application of these methods to different oils will be discussed.
