Effect of Blended Feedstock on Pyrolysis Oil Composition

Kristin Smith, Katherine Gaston

Research output: NRELPoster


Current techno-economic analysis results indicate biomass feedstock cost represents 27% of the overall minimum fuel selling price for biofuels produced from fast pyrolysis followed by hydrotreating (hydro-deoxygenation, HDO). As a result, blended feedstocks have been proposed as a way to both reduce cost as well as tailor key chemistry for improved fuel quality. For this study, two feedstocks were provided by Idaho National Laboratory (INL). Both were pyrolyzed and collected under the same conditions in the National Renewable Energy Laboratory's (NREL) Thermochemical Process Development Unit (TCPDU). The resulting oil properties were then analyzed and characterized for statistical differences.
