Biofuels production from lignocellulosic biomass is hindered by high conversion costs in the generation of high-quality fuels, driving research towards the development of new pathways with less severe conditions, higher yields and higher-quality products. This presentation will highlight a market-responsive biorefinery concept based on bio-derived methanol as the key intermediate, and the development of novel pathways to generate advantaged blendstocks for gasoline, jet, and diesel fuels. The high-octane gasoline pathway generates an advantaged fuel that is rich in 2,2,3-trimethylbutane (“triptane”), having a pure-component RON value of 112 and a sensitivity of 11. This pathway also produces olefins that can be coupled to a jet blendstock that meets 5 key ASTM International specifications. Fuel property testing results for these two products will be presented. The dehydrogenative coupling of methanol generates poly(oxymethylene)ethers (POMEs), which are promising as diesel fuel blendstocks due to their high cetane values and extremely low sooting behavior. In addition to the development of a one-step production process for the generation of POMEs from methanol, this talk will highlight a “fuel-property first” approach to end-group exchange chemistry that further enhances the fuel properties of POME molecules. These pathways being developed here lead to higher-quality, higher-value fuel products that may enable market pull over processes that generate a regular gasoline, kerosene (jet) or distillate blendstocks.
