As the bioenergy industry focuses on the near-term development of conversion pathways from biomass feedstocks to infrastructure-compatible fuel blendstocks, analysis capabilities and models are essential for assessing the values of biomass-derived blendstocks based on its fuel properties and the constraining parameters for blending them with petroleum-derived products. Funding from DOEâ??s Bioenergy Technologies Office (BETO) has enabled the analysis team to develop both linear programming models (Aspen PIMS) and process models (Aspen Plus and Aspen HYSYS) to meet the new analysis needs. In addition to developing these analysis tools, the team has also utilized published experimental blending data to validate the results of the models and to improve blend property predictions. These models are already playing a vital role at NREL in understanding the potential to integrate fuel products from biomass conversion pathways under BETOâ??s research and development portfolio.

This presentation will focus on (1) an overview of the analysis approaches and process models developed under this effort, (2) the benefits for utilizing the tools for assessing biomass-derived blendstocks, (3) examples of blending analysis results, (4) comparison of results from blending models relative to experimental data and (5) future work for this effort in assessing blending of oxygenated compounds.
