20130118914 | METHOD FOR REMOVING OXYGEN FROM A REACTION MEDIUM - The invention relates to a method for removing oxygen from a water containing reaction medium. A pair of electrodes (cathode and anode), are added to the medium, with a surfactant attached to the surface of at least one of the cathode and anode. The medium is kept at an acidic pH, and an electrical current is applied. Oxygen is drawn to the electrodes, displacing surfactant, and reacts with H | 05-16-2013 |
20140102987 | PLANT BASED MATERIAL USEFUL IN ADSORBING PETROLEUM PRODUCTS, PROCESSES FOR MAKING THESE, AND USES THEREOF - The invention relates to methods for making completely biodegradable, hydrophobic, oleophilic plant based materials which are useful in adsorption of petroleum products. The materials have an average diameter of from 1 to 5 mm, and an ash content of from 10% to 30%. The non-paraffin coating is an animal fat product, preferably produced by dissolving a pure animal fat and using this as the coating material. | 04-17-2014 |
20140194539 | CARBON DIOXIDE CONVERSION TO HYDROCARBON FUEL VIA SYNGAS PRODUCTION CELL HARNESSED FROM SOLAR RADIATION - A process for converting carbon dioxide to hydrocarbon fuels using solar energy harnessed with a solar thermal power system to create thermal energy and electricity, using the thermal energy to heat a fuel feed stream, the heated fuel feed stream comprising carbon dioxide and water, the carbon dioxide captured from a flue gas stream, converting the carbon dioxide and water in a syngas production cell, the syngas production cell comprising a solid oxide electrolyte, to create carbon monoxide and hydrogen, and converting the carbon monoxide and hydrogen to hydrocarbon fuels in a catalytic reactor. In at least one embodiment, the syngas production cell is a solid oxide fuel cell. In at least one embodiment, the syngas production cell is a solid oxide electrolyzer cell. | 07-10-2014 |
20150184085 | DEMULSIFICATION OF EMULSIFIED PETROLEUM USING CARBON DIOXIDE AND RESIN SUPPLEMENT WITHOUT PRECIPITATION OF ASPHALTENES - Methods for demulsifying an emulsified petroleum source having a predetermined resin-to-asphaltene ratio without substantial aggregation or precipitation of asphaltenes may include adding a resin supplement to the emulsified petroleum source to form a resin-supplemented emulsion having a resin-to-asphaltene ratio above a predetermined critical value. An acidic-to-basic ratio of acidic functional groups to basic functional groups in the supplemented emulsion may be adjusted to be from about 0.25 to about 4.0. The resin-supplemented emulsion may be contacted with carbon dioxide to form an initial mixture having an emulsified oil phase and an emulsified aqueous phase. The initial mixture may be stabilized to facilitate rupture of the resin-supplemented emulsion, to cause phase separation, and to allow removal of a separated oil phase. The resin-to-asphaltene ratio being above the predetermined critical value in the supplemented emulsion maintains asphaltene suspension during demulsification, such that asphaltene agglomeration and precipitation are avoided. | 07-02-2015 |

20150315486 | Demulsification and Extraction of Biochemicals from Crude and its Fractions Using Water and Subcritical/Supercritical Carbon Dioxide as Proton Pump with pH Tuning without Precipitating Oil Components - A demulsification process for extracting surface active biochemical products from crude oil and its fractions when they are used as feedstock during biochemical productions utilizes subcritical/supercritical CO | 11-05-2015 |
20150343416 | Activation of Waste Metal Oxide as an Oxygen Carrier for Chemical Looping Combustion Applications - A process for producing black powder oxygen carriers for use in a chemical looping combustion unit includes the steps of: (a) removing and collecting the black powder waste material that was formed in a gas pipeline; (b) pre-treating the collected black powder to adjust its spherical shape to avoid attrition and fines production; and (c) activating the black powder to increase its reactivity rate and produce the black powder oxygen carrier that is suitable for use in the chemical looping combustion process as an oxygen carrier. | 12-03-2015 |
20150353847 | Integrated Systems And Methods For Separation And Extraction Of Polynuclear Aromatic Hydrocarbons, Heterocyclic Compounds, And Organometallic Compounds From Hydrocarbon Feedstocks - Methods are provided for extracting heterocyclic compounds, organometallic compounds, and polynuclear aromatic hydrocarbons from a hydrocarbon feedstock such as crude oil or a crude fraction. The heterocyclic compounds and organometallic compounds are removed from the hydrocarbon feedstock through one or more successive extractions to form a first raffinate. The extractions use a first solvent system containing an ionic liquid formed from carbon dioxide and water. The polynuclear aromatic hydrocarbons are removed from the first raffinate using a second solvent system containing an aprotic solvent such as NMP, DMSO, aromatics, or combinations thereof. The extracted compounds remain chemically intact and may be fractionated for further applications. Further methods are provided for producing a hydrocarbon raffinate having reduced levels of heterocyclic compounds, organometallic compounds, and 2-4 cycle polynuclear aromatic hydrocarbons. | 12-10-2015 |
