Abstract
Processes for producing alcohols from biomass are provided. The processes utilize supercritical methanol to depolymerize biomass with subsequent conversion to a mixture of alcohols. In particular the disclosure relates to continuous processes which produce high yields of alcohols through recycling gases and further employ dual reactor configurations which improve overall alcohol yields. Processes for producing higher ethers and olefins from the so-formed alcohols, through alcohol coupling and subsequent dehydration are also provided. The resulting distillate range ethers and olefins are useful as components in liquid fuels, such as diesel and jet fuel.
