    摘要: Disclosed is a process and an adsorbent for the separation of ethanol associated oxygenates from a dilute mixture of ethanol and associated oxygenates in water in the presence of organic compounds derived from a biofermentation process. After pretreatment, the separation is carried out in a simulated moving bed adsorption system employing an stationary phase adsorbent comprising fluorinated carbon or modified C18 silica gel selective for the adsorption of ethanol and associated oxygenates, such as 2,3-butanediol, with a mobile phase desorbent selected from the group consisting of methanol, ethanol, propanol, and methyl tertiary butyl ether. The process is useful for removing water from dilute aqueous mixtures of organic compounds comprising ethanol in dilute concentration in water and produced by fermentation, biomass extraction, biocatalytic and enzymatic processes which are not economically recoverable by conventional distillation methods.

    摘要: A process for converting a substrate such as carbon monoxide to useful chemicals has been developed. The process involves providing a substrate comprising CO to a bioreactor which contains a culture of one or more micro-organisms and anaerobically fermenting the substrate to produce 2,3-butanediol (BDO). The BDO is next converted to one or more of butane, butadiene and/or methyl ethyl ketone which in turn can be converted to other compounds. The source of the CO can be an industrial process such as the ferrous metal products manufacturing. The microorganism can be Clostridium autoethanogenum, Clostridium ljundahlii or Clostridium ragsdalei.
