| 20120330057 | PROCESS FOR THE EXTRACTION OF HIGH MOLECULAR WEIGHT NAPHTHENIC ACIDS FROM CALCIUM NAPHTHENATE SALTS - A method for recovering high molecular weight naphthenic tetra-acids, particularly ARN acids from a calcium naphthenate deposit. Calcium naphthenate deposits contain large amounts of calcium naphthenate salts of ARN acids. The method dual solvent extraction process in which the naphthenic tetra-acids chemically bound as calcium naphthenate salts are converted into free acid monomers by an aqueous acid. The resulting free acid monomers are then dissolved into an organic solvent phase and the counterions dissolve in the aqueous acid phase. The naphthenic tetra-acids are then recovered from the organic solvent phase. | 12-27-2012 |

| 20160002045 | Large Scale Oxidized Graphene Production for Industrial Applications - Existing methods of producing high quality graphene/graphite oxides are generally accomplished by exfoliating graphite into flakes and oxidizing the graphite flakes with strong oxidizers under extreme conditions and require careful purification. The oxidizers are typically strong acids used in high concentrations at elevated temperatures requiring complicated purification processes to yield oxidized graphene/sheets. The existing processes can cost up to $12,000/gram. This invention uses a mild oxidant combined with mechanical processing where the sole products are oxidized graphite/graphene and water without the need for further purification. | 01-07-2016 |
