| 20100012583 | ADVANCED BIOREFINERY PROCESS - The present invention is a method for refining native biomass to extremely fine and highly disrupted particles using high shear and/or cavitation in combination with high temperature and high or low pH conditions which dissolve biomass to a high percentage. The method of the present invention results in a high percentage of hydrolysis, in many cases near theoretical levels, in short residence times while minimizing inputs over other methods, using low chemical inputs, and optionally with no chemical inputs in certain stages compared to existing processes. The method of the present invention also uses minimal electrical energy inputs and conserves heat energy within the process and reduces equipment requirements while producing concentrated products. | 01-21-2010 |
| 20100230350 | Method and apparatus for treating selenium-containing wastewater - A method and an apparatus for treating selenium-containing wastewater, in which wastewater containing hexavalent selenium is subjected to reduction treatment, selenium can be effectively removed at a small amount of metal leached, and, preferably, sludge produced during treatment is white, thereby facilitating the disposal of the sludge. The selenium-containing wastewater is brought into contact with an alloy or a mixture of metallic titanium and a first metal other than metallic titanium to partially leach the first metal, thereby subjecting selenium in the wastewater to reduction treatment. | 09-16-2010 |
| 20100237010 | USE OF PVPP TO REMOVE CONTAMINANTS FROM PRODUCED WATER OF AN OIL OR GAS WELL - In accordance with the present invention there is provided a method of removing acidic and/or aromatic contaminants, such as benzene, xylene, toluene, phenols and polyphenols, from produced water of an oil or gas well. The method comprises the step of contacting the produced water with polyvinylpolypyrrolidone (PVPP) to remove the contaminants from said water. | 09-23-2010 |
| 20110079556 | SEPARATION OF SOLIDS FROM LIQUIDS BY FILTRATION AND CENTRIFUGATION - A method and apparatus for efficiently performing solid phase extraction techniques for cleanup of samples to be used in analysis for pesticides, food products, etc. An insert to a centrifuge tube is disclosed which provides for mixing the solid and liquid, after which centrifuging is used to separate the liquid from the solid, after processing it through an appropriate filter. | 04-07-2011 |
| 20110079557 | MATERIALS FOR THE SOLID/LIQUID EXTRACTION OF HEAVY METAL IONS, CONTAINING SUPPORTED N-FUNCTIONALIZED POLYAZACYLOALKANES - The present invention relates to a material notably adapted for the extraction of metal cations in an aqueous medium, comprising a solid support on which are attached polyazacycloalkane compounds having a ring including at least 4 nitrogen atoms, and wherein the nitrogen atoms of the ring are substituted with coordinating groups, which each are independently:

| 20110094961 | EXTRACTION OF SOLUTE FROM SOLUTE-BEARING MATERIAL - This invention is directed to a process for separating a solute from a solute-bearing material. A substantial amount of solute is extracted from the solute-bearing material by contacting particles of the solute-bearing material with globules of an extraction solvent. The particle size of the solute-bearing material and the globule size of the extraction solvent are balanced such that little if any solute or extraction solvent remains in the solute-bearing material. | 04-28-2011 |
| 20110192792 | Method and Apparatus for Processing Algae - Methods and apparatus for processing algae are described in which a hydrophilic ionic liquid is used to lyse algae cells. The lysate separates into at least two layers including a lipid-containing hydrophobic layer and an ionic liquid-containing hydrophilic layer. A salt or salt solution may be used to remove water from the ionic liquid-containing layer before the ionic liquid is reused. The used salt may also be dried and/or concentrated and reused. The method can operate at relatively low lysis, processing, and recycling temperatures, which minimizes the environmental impact of algae processing while providing reusable biofuels and other useful products. | 08-11-2011 |
| 20110192793 | Method and Apparatus for Lysing and Processing Algae - Methods and apparatus for processing algae are described in which a hydrophilic ionic liquid is used to lyse algae cells at lower temperatures than existing algae processing methods. A salt or salt solution is used as a separation agent and to remove water from the ionic liquid, allowing the ionic liquid to be reused. The used salt may be dried or concentrated and reused. The relatively low lysis temperatures and recycling of the ionic liquid and salt reduce the environmental impact of the algae processing while providing biofuels and other useful products. | 08-11-2011 |
| 20120055873 | GREEN SYNTHESIS OF NANOMETALS USING PLANT EXTRACTS AND USE THEREOF - The present invention relates to methods of making and using and compositions of metal nanoparticles formed by green chemistry synthetic techniques. For example, the present invention relates to metal nanoparticles formed with solutions of plant extracts and use of these metal nanoparticles in removing contaminants from soil and groundwater and other contaminated sites. In some embodiments, the invention comprises methods of making and using compositions of metal nanoparticles formed using green chemistry techniques. | 03-08-2012 |
| 20130299423 | Modular Assembly of Metal-Organic Super-Containers Incorporating Calixarenes - A new strategy to design container molecules is presented. Sulfonylcalix[4]arenes, which are synthetic macrocyclic containers, are used as building blocks that are combined with various metal ions and tricarboxylate ligands to construct metal-organic ‘super-containers’ (MOSCs). These MOSCs possess both endo and exo cavities and thus mimic the structure of viruses. The synthesis of MOSCs is highly modular, robust, and predictable. | 11-14-2013 |
| 20140263050 | POLYOL-INDUCED EXTRACTION OF WATER FROM ORGANIC LIQUIDS - Disclosed are methods of extracting water from a composition of an organic liquid and water, using a polyol. | 09-18-2014 |
