This work develops a surrogate fuel that reproduces the octane blending of a market gasoline with ethanol. It first extends our previous investigation that reported strong, non-linear blending for ethanol/paraffin and ethanol/aromatic mixtures (Foong et al., Fuel 2014 p. 727) to consider mixtures of ethanol/cycloparaffin, ethanol/olefin, and hydrocarbons from different groups. On the molar basis, ethanol blends synergistically with cyclohexane and 1-hexene, whereas toluene blends antagonistically with ethanol and all hydrocarbons studied. Various alternative surrogate formulations are then considered given the observed inadequacy of toluene reference fuels (TRFs, mixtures of iso-octane, n-h..View full abstract
