Publication number: 20130102043Abstract: A process for producing ethanol including a combination of biochemical and synthetic conversions results in high yield ethanol production with concurrent production of high value coproducts. An acetic acid intermediate is produced from carbohydrates, such as corn, using enzymatic milling and fermentation steps, followed by conversion of the acetic acid into ethanol using esterification and hydrogenation reactions. Coproducts can include corn oil, and high protein animal feed containing the biomass produced in the fermentation.Type: ApplicationFiled: July 17, 2012Publication date: April 25, 2013Applicant: ZEACHEM, INC.Inventors: Dan Verser, Timothy J.

Publication number: 20090281354Abstract: A method is disclosed for the recovery of an organic acid from a dilute salt solution in which the cation of the salt forms an insoluble carbonate salt. An amine and CO2 are introduced to the solution to form the insoluble carbonate salt and a complex between the acid and the amine. The acid/amine complex is thermally dissociated, or “cracked”, in the presence of a water immiscible solvent in which the amine is selectively soluble and in which the acid is not appreciably soluble. The organic acid may then be recovered from the water by any suitable means such as distillation, reactive distillation, extraction, or reactive extraction.Type: ApplicationFiled: May 7, 2009Publication date: November 12, 2009Applicant: ZEACHEM, INC.Inventors: Gal Mariansky, Kevin Carlin, Dan Verser

Publication number: 20060222585Abstract: A process for the recovery of organic acids from dilute solutions such as those produced by fermentation, when the organic acids are present as dilute salt solutions, is provided. The organic acid production process is integrated with a nitrogen fertilizer production process by utilizing wasted chemical energy from the fertilizer process for acidification of the organic acid solution.Type: ApplicationFiled: January 9, 2004Publication date: October 5, 2006Applicant: ZEACHEM, INC.Inventors: Dan Verser, Tim Eggeman

Publication number: 20060127999Abstract: A process for producing ethanol by the conversion of carbohydrates from a corn dry milling process in which the bottoms fraction from distillation of ethanol in a conventional yeast fermentation is used in a process including a combination of biochemical and synthetic conversions. The process results in high yield ethanol production with concurrent production of high value coproducts. An acetic acid intermediate is produced from bottoms fraction, followed by conversion of the acetic acid into ethanol using esterification and hydrogenation reactions. Coproducts of the process include a high protein content solids fraction produced in the fermentation.Type: ApplicationFiled: January 24, 2006Publication date: June 15, 2006Applicant: ZEACHEM INC.Inventors: Dan Verser, Timothy Eggeman

Publication number: 20050256337Abstract: A method is disclosed for the recovery of an organic acid from a dilute salt solution in which the cation of the salt forms an insoluble carbonate salt. A tertiary amine and CO2 are introduced to the solution to form the insoluble carbonate salt and a complex between the acid and an amine. A water immiscible solvent, such as an alcohol, is added to extract the acid/amine complex from the dilute salt solution to a reaction phase. The reaction phase is continuously dried and a product between the acid and the solvent, such as an ester, is formed.Type: ApplicationFiled: January 28, 2005Publication date: November 17, 2005Applicant: ZeaChem Inc.Inventors: Dan Verser, Timothy Eggeman
