| 20120116063 | METHODS AND SYSTEMS FOR PROCESSING LIGNOCELLULOSIC MATERIALS AND RELATED COMPOSITIONS - A method comprising: (a) providing a lignocellulosic substrate; (b) contacting said lignocellulosic substrate with an extractant comprising a water-soluble organic solvent to form an extracted substrate and a miscella; (c) removing miscella from said extracted substrate; and (d) hydrolyzing said extracted substrate using a chemically catalyzed process. | 05-10-2012 |
| 20120058526 | Methods and Systems for Processing Sugar Mixtures and Resultant Compositions - A method including: (a) selectively reacting a first sugar in a mixture which includes at least one second sugar to form a product mixture comprising a product of said first sugar; (b) separating said product of said first sugar from said product mixture; and (c) separating at least one of said at least one second sugar from said product mixture. | 03-08-2012 |
| 20110178290 | PROCESS FOR THE PRODUCTION OF HCL GAS FROM CHLORIDE SALTS AND FOR THE PRODUCTION OF CARBOHYDRATES - A process for the co-production of gaseous HCl and a salt product comprising a cation and an anion, which process comprises the steps of a. providing an aqueous solution comprising protons, chloride anions, and cations and anions of the salt product, b. bringing the solution into contact with a substantially immiscible extractant, the extractant comprising: 1) an oil soluble amine, which amine is substantially water insoluble both in free and in salt form; and 2) a carrier solvent for the amine; whereupon HCl selectively transfers to the extractant to form an HCl-carrying extractant and a chloride depleted aqueous solution containing the salt product; c. separating the HCl-carrying extractant from the chloride-depleted aqueous solution; and d. distilling HCl from the separated HCl-carrying extractant to form gaseous HCl and HCl depleted extractant. | 07-21-2011 |
| 20110028710 | PROCESS FOR THE RECOVERY OF HCL FROM A DILUTE SOLUTION THEREOF AND EXTRACTANT COMPOSITION FOR USE THEREIN - There is provided a process for the recovery of HCI from a dilute solution thereof, comprising bringing a dilute aqueous HCI solution into contact with a substantially water-immiscible extractant, the extractant comprising an oil soluble amine, which amine is substantially water insoluble both in free and in salt form; an oil soluble weak organic acid having a pKa above 3, which acid is substantially water insoluble both in free and in salt form; and a solvent for the amine and organic acid; whereupon HCI selectively transfers to the extractant to form an HCI-carrying extractant, and treating the HCI-carrying extractant to obtain gaseous HCI. Also provided is the extractant composition. | 02-03-2011 |
| 20100093995 | PROCESS FOR THE RECOVERY OF HCL FROM A DILUTE SOLUTION THEREOF - The invention provides a process for the recovery of HCl from a dilute solution thereof, comprising: a) bringing a dilute aqueous HCl solution into contact with a substantially immiscible extractant, said extractant comprising: 1) an oil soluble amine which amine is substantially water insoluble both in free and in salt form; 2) an oil soluble organic acid which acid is substantially water insoluble both in free and in salt form; and 3) a solvent for the amine and organic acid; whereupon HCl selectively transfers to said extractant to form an HCl-carrying extractant; and b) treating said HCl-carrying extractant to obtain gaseous HCl. | 04-15-2010 |
