the catalytic synthesis of such ethers by reductive etherification/O‐alkylation of alcohols using building blocks that can be sourced from biomass. We find that long‐chain branched ethers have several properties that make them superior lubricants to the mineral oil and synthetic base oils used today. These ethers provide a class of potentially renewable alternatives to conventional lubricants produced

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.

Beschrieben wird ein Verfahren zur Reinigung von Abwässern, die aus der Herstellung von Alkoholen stammen, wobei diese Alkoholherstellung eine Aldolisierungsreaktion, eine nachfolgende Hydrierung sowie eine abschließende Alkoholdestillation umfaßt. Die Abwässer enthalten verschiedene Abwasserfraktionen aus den verschiedenen Schritten der Alkoholherstellung. Das Verfahren zur Reinigung dieser Abwässer schließt eine Ansäuerung und Extraktion von einer oder mehrerer dieser Abwasserfraktionen ein und zeichnet sich dadurch aus, daß eine oder mehrere der Abwasserfraktionen im Verlauf des Verfahrens mit einem Koalisierfilter in Kontakt gebracht werden.
