BackgroundThe present work is part of a cross-disciplinary national Swedish research project on advanced tailor-made biofuels that aims at identifying drop-in biofuel options for the transport sector that combine excellent combustion properties with sustainable production pathways. A key aspect of the research collaboration is a close dialogue between the experimental engine research teams investigating engine performance and biofuel handling and combustion in the engine systems, and the energy systems research groups analyzing the biomass potential, production aspects for the respective biofuels, and performance of the entire value chain from well-to-wheel (WTW). The present paper addresses the methodology and primary results of the biofuel production pathway assessment for the Diesel fuel alternatives identified for assessment within the project.
Gasfication-based Butanol-based Ethanol-based
Eight diesel fuel alternatives – production pathways
Preliminary results• Highest biomass to 2-Ethylhexanol conversion via ethanol
• Varying spectrum of by-products
• 2-Ethylhexanol production performs worse from an energyefficiency perspective than ”conventional” biofuels (due to additional conversion steps)
• Use phase benefits such as higher blend-in ratios, existingdistribution infrastructure and reduced NOx or particleemissions may change the WTW picture
Outlook• Evaluation of process concepts using attributional Life Cycle
Assessment accounting for by-products by system expansion with product substition (to be presented at TMFB conference 20-22 June 2017)
• Guidance towards promising pathways (platform chemicals) based on critical parameters for 2-Ethylhexanol production
• Combination of WTT data with engine combustionexperiments to evaluate the whole WTW performance
• Multi-criteria analysis to illustrate potential for advancedbiofuels from different perspectives
Research challenge• Multitude of potential fuels in
combination with numerous productionpathways available
Methodology• Screening of promising fuels• Production pathway analaysis• Choice of industrially relevant pathways• Process synthesis and analysis of process
integration opportunities• Identification of critical factors for
sustainability performance
• The methodology is illustrated for2-Ethylhexanol (2-EH)
