Abstract: A method including: introducing a feed comprising an alcohol and an activator into a reactor comprising a solid acid catalyst; contacting the alcohol and the activator in the presence of the solid acid catalyst under conditions effective to convert at least a portion of the alcohol and the activator to produce a product stream comprising C8-C16 olefins and water; thermally contacting at least a portion of the C8-C16 olefins and/or water with a working fluid to heat the working fluid to form a heated working fluid; and introducing at least a portion of the C8-C16 olefins and water from the product stream into a distillation column and forming a bottoms stream comprising a majority of the C8-C16 olefins from the product stream, wherein a reboiler thermally coupled to the distillation column is at least partially heated by the heated working fluid.

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.

Abstract: Provided are two-stage processes by which primary alcohols such as ethanol or 1-butanol are converted into distillate-range ethers and olefins utilizing Guerbet coupling followed by intermolecular dehydration. The ethers can be used, for example, as cetane-improvers in diesel fuel, while the olefins can be hydrogenated to afford paraffins.
