Patent number: 11453636Abstract: A method is provided for separating a dicarboxylic acid product from a mixture containing such dicarboxylic acids. The method involves: providing a dicarboxylic acid-containing mixture of which at least 35% of the carboxylic acid content of the mixture is a dicarboxylic acid product of interest; running an extraction of said dicarboxylic acid-containing mixture through a chromatographic column configured with an amphoteric resin, such that the dicarboxylic acid product elutes preferentially from the dicarboxylic acid-containing mixture. In certain embodiments, the dicarboxylic acid product of interest can be a glucaric or gluconic acid product from a mixture of either or both of these with still other carboxylic acids.Type: GrantFiled: June 20, 2018Date of Patent: September 27, 2022Assignee: ARCHER DANIELS MIDLAND COMPANYInventors: Pam Anklam, William Chris Hoffman, Mitchell Schultz, John G.

Patent number: 11078174Abstract: A process is provided for making esters of FDCA, in which an aqueous feed comprising glucaric acid is first reacted with a high boiling first alcohol in the presence of an acid catalyst and with removing water during the reaction, to form a first product mixture comprising a first ester of FDCA and the high boiling first alcohol, then unreacted high boiling first alcohol is removed from the first product mixture. The first ester of FDCA and the high boiling first alcohol is then transesterified with a lower boiling second alcohol selected from the group consisting of methanol, ethanol, isopropanol and n-propanol, to form a second product mixture comprising a second ester of FDCA with the lower boiling second alcohol, and the second ester of FDCA with the lower boiling second alcohol is recovered.Type: GrantFiled: June 20, 2018Date of Patent: August 3, 2021Assignee: ARCHER DANIELS MIDLAND COMPANYInventors: Pam Anklam, William Chris Hoffman, Stephen J.

Patent number: 9174902Abstract: A method for reducing contaminants in the production of a bio-derived glycol product of polyol hydrogenolysis is described. The method involves subjecting an aqueous, polyol product mixture (from the hydrogenolysis conversion of biologically-derived carbohydrate feedstock) to ion-exclusion chromatography to separate and reduce impurities from an eluant fraction containing a desired product, and distilling the eluant fraction to yield the desired product (e.g., propylene glycol or ethylene glycol). The reaction product mixture can be introduced into a continuous ion-exclusion chromatography system to reduce the impurities and produce in a high-throughput manner a finished otherwise commercially acceptable glycol product.Type: GrantFiled: August 21, 2013Date of Patent: November 3, 2015Assignee: Archer Daniels Midland Co.Inventors: John G.

Patent number: 8177980Abstract: The present invention provides methods of separating at butanediol compound from a mixture containing polyhydric alcohols and butanediol compounds. The mixture of polyhydric alcohols typically contains propylene glycol and ethylene glycol in addition to the butanediol contaminants. Butanediol contaminants are removed by contacting the mixture with a chromatographic matrix. Either the butanediol compounds or the non-butanediol compounds adsorb to the chromatographic matrix. If desired, the adsorbed compounds may be eluted from the matrix, purified and used in products.Type: GrantFiled: September 22, 2008Date of Patent: May 15, 2012Assignee: Archer Daniels Midland CompanyInventors: Ahmad K.

Patent number: 8088710Abstract: The present invention is directed to a method of preparing compositions enriched in compounds containing carbon chains of varying degrees of unsaturation using argentation chromatography. The present method utilizes an argentized cationic resin or a conditioned argentized alumina to separate compounds containing saturated or mono-unsaturated carbon chains from compounds having polyunsaturated carbon chains present in a starting composition. The invention is particularly useful for preparing a composition enriched in polyunsaturated fatty acid alkyl esters from mixtures of fatty acid esters in a starting composition derived from vegetable oils. The present invention is also directed to a method of preparing a conditioned argentized alumina adsorbent having increased selectivity for compounds containing one or more polyunsaturated carbon chains.Type: GrantFiled: December 16, 2009Date of Patent: January 3, 2012Assignee: Archer Daniels Midland CompanyInventors: Thomas P.

Patent number: 7828978Abstract: Simultaneous synthesis and purification of a fatty acid monoester biodiesel fuel from a triacylglycerol feedstock is described. In an exemplary method, the triacylglycerol feedstock is continuously contacted with a catalytic chromatographic bed comprising a first (solid phase) basic catalyst through a first port of a simulated moving bed chromatographic apparatus. A monohydric alcohol and optional second (mobile phase) basic catalyst is continuously contacted with the catalytic chromatographic bed through a second port and pumped in a first direction toward the triacylglycerol feedstock to contact the triacylglycerol in a reaction zone of the catalytic chromatographic bed where the fatty acid monoester and glycerol coproduct are formed. The fatty acid monoester is removed from the reaction zone through a product port of the simulated moving bed apparatus.Type: GrantFiled: June 8, 2006Date of Patent: November 9, 2010Inventors: Doug Geier, John G. Soper

Patent number: 7705170Abstract: The present invention is directed to a method or preparing fatty acid alkyl esters from fatty acids contained in co-product streams, or waste or recycled fatty acid stock. The present method utilizes an acidic resin to convert the fatty acid stock into esters. The present method encompasses the use of reactive simulated moving bed chromatography, wherein above about 95 percent of the fatty acid stock is converted to fatty acid alkyl esters. The present method has been optimized to separate the ester product from the raffinate stream formed during the chromatographic process, thereby improving the yield of the esterification and preventing acid hydrolysis of the ester.Type: GrantFiled: April 11, 2005Date of Patent: April 27, 2010Assignee: Archer-Daniels-Midland CompanyInventors: Douglas F. Geier, Ahmad K. Hilaly, John G. Soper
