Patent number: 8647851Abstract: A stable continuous method for producing ethanol from the anaerobic bacterial fermentation of a gaseous substrate containing at least one reducing gas involves culturing in a fermentation bioreactor anaerobic, acetogenic bacteria in a liquid nutrient medium; supplying the gaseous substrate to the bioreactor; and manipulating the bacteria in the bioreactor by reducing the redox potential, or increasing the NAD(P)H TO NAD(P) ratio, in the fermentation broth after the bacteria achieves a steady state and stable cell concentration in the bioreactor. The free acetic acid concentration in the bioreactor is maintained at less than 5 g/L free acid. This method allows ethanol to be produced in the fermentation broth in the bioreactor at a productivity of greater than 10 g/L per day. Both ethanol and acetate are produced in a ratio of ethanol to acetate ranging from 1:1 to 20:1.Type: GrantFiled: December 8, 2011Date of Patent: February 11, 2014Assignee: Ineos Bio LimitedInventors: James L.

Patent number: 7421959Abstract: A multi-step process is provided in which waste material is processed in two or more steps. Specifically, an earlier step of the process heats the waste material at a first temperature. This results in a release of vapors for materials having a boiling point that is lower than the first temperature. A subsequent step of the process heats some or all of the remaining waste material at a second temperature, which is preferably higher than the first temperature. The subsequent heating results in a release of additional vapors for those materials having a boiling point that is lower than the second temperature. A system configured to carry out the process is also disclosed.Type: GrantFiled: October 7, 2005Date of Patent: September 9, 2008Assignee: Rineco Chemical Industries, Inc.Inventors: John P.

Patent number: 7196218Abstract: 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.Type: GrantFiled: May 5, 2004Date of Patent: March 27, 2007Assignees: Celanese International Corporation, Bioengineering Resources, Inc.Inventors: James L.
