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.

The invention relates to a process and a plant for producing pure methanol, wherein the crude methanol stream discharged from a methanol synthesis unit is decompressed in a decompression vessel, is subsequently at least partially freed of low-boiling by-products in a prerun column and is then supplied to a single- or multi-stage methanol purification apparatus from which a pure methanol product stream is finally discharged. According to the invention the tops product stream from the prerun column is subjected to a scrubbing step with a methanol-selective scrubbing medium, thus at least partially recovering methanol present and sending a methanol-depleted tops product stream to the offgas disposal apparatus.
