    摘要: A modified water-immiscible solvent useful in the extraction of acetic acid from aqueous streams is a substantially pure mixture of isomers of highly branched di-alkyl amines. Solvent mixtures formed of such a modified solvent with a desired co-solvent, preferably a low boiling hydrocarbon, are useful in the extraction of acetic acid from aqueous gaseous streams. An anaerobic microbial fermentation process for the production of acetic acid employs such solvents, under conditions which limit amide formation by the solvent and thus increase the efficiency of acetic acid recovery. Methods for the direct extraction of acetic acid and the extractive fermentation of acetic acid also employ the modified solvents and increase efficiency of acetic acid production. Such increases in efficiency are also obtained where the energy source for the microbial fermentation contains carbon dioxide and the method includes a carbon dioxide stripping step prior to extraction of acetic acid in solvent.

    摘要: A process is provided for fermentation of syngas that is effective for reducing conductivity and providing an alcohol STY of about 10 g ethanol/(L·day). The process includes introducing the syngas into a reactor vessel and providing a nitrogen feed rate to the reactor vessel of about 100 mg or more nitrogen/gram of cells produced. Fermentation of the syngas is effective for providing a fermentation medium having an average conductivity of about 16 mS/cm or less and an STY of 10 g ethanol/(L·day) or more.
