Tóm tắt

 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. In this report, we present a market-responsive biorefinery concept based on methanol as the key intermediate, which generates high-octane gasoline (HOG) and jet fuel blendstocks from biomass. Process models and techno-economic analysis are linked with both fundamental and applied catalyst development research to quantify the impact of catalyst advancements on process economics. By facilitating reincorporation of C<
