Patent application number | Description | Published |
20100155330 | TARGET MATERIAL REMOVAL USING RARE EARTH METALS - The present invention is directed to the removal of one or more selected target materials from various streams using a rare earth metal-containing fixing agent. | 06-24-2010 |
20120074071 | PROCESS FOR TREATING WATERS AND WATER HANDLING SYSTEMS TO REMOVE SCALES AND REDUCE THE SCALING TENDENCY - The present disclosure includes an embodiment to a method for treating water and/or a water handling system to decrease deposit formation and/or to remove a deposit. More particularly, to a method for treating water and/or a water handling system with one or more rare earths to decrease deposit formation and/or to remove a deposit. Struvite is an example of deposit material that can be removed and/or deposition inhibited by treating a water and/or water handling system with one or more earths. | 03-29-2012 |
20120103909 | PARTICULATE CERIUM DIOXIDE AND AN IN SITU METHOD FOR MAKING AND USING THE SAME - This disclosure relates generally to methods and compositions for removing contaminants from streams and is particularly concerned with methods and compositions for removing contaminants from municipal wastewaters, municipal drinking waters and recreational waters. The present disclosure is to particulate cerium, more particularly to particulate cerium (IV) formed by an in situ oxidative process and to a method for removing target materials from a target material-containing stream using particulate cerium formed in situ. | 05-03-2012 |
20120187047 | RARE EARTH REMOVAL OF HYDRATED AND HYDROXYL SPECIES - This disclosure relates generally to methods and rare earth-containing additives for removing target materials in the form of hydroxides, carbonates, hydrates, or oxyhydroxyls from, a typically aqueous, liquid medium. | 07-26-2012 |
20120187337 | RARE EARTH REMOVAL OF PHOSPHORUS-CONTAINING MATERIALS - This disclosure relates generally to methods and rare earth-containing additives for removing inorganic and organic phosphorus-containing target materials. | 07-26-2012 |
20120223022 | CONTAMINANT REMOVAL FROM WATERS USING RARE EARTHS - The present disclosure is directed to the use of rare earth-containing additives, particularly rare earth-containing additives comprising rare earths of plural oxidation states, to remove, particularly from recreational waters, various target materials, such as disinfectant by-products and precursors thereof, phosphates, and organophosphates. | 09-06-2012 |
20120238683 | COMPOSITION AND PROCESS FOR MAKING THE COMPOSITION - An aggregate composition and process for making the aggregate composition. The aggregate composition includes an insoluble rare earth-containing compound and a polymer binder. The insoluble rare earth-containing compound can include one or more of cerium, lanthanum, or praseodymium. A suitable insoluble cerium-containing compound can be derived from cerium carbonate or a cerium salt. In a specific embodiment, the aggregate composition consists essentially of one or more cerium oxides, the polymer binder and optionally a flow aid. A process for making the composition includes mixing the insoluble rare earth-containing compound with a polymer binder to form a mixture, and subjecting the mixture to mechanical, chemical and/or thermal treatment to adhere the rare earth compound to the polymer binder. The aggregate composition can be used in a variety of fluid treatment applications to remove one or more chemical and biological contaminants in a fluid. | 09-20-2012 |
20120261345 | RARE EARTH REMOVAL OF HYDRATED AND HYDROXYL SPECIES - This disclosure relates generally to methods and rare earth-containing additives for removing target materials in the form of hydroxides, carbonates, hydrates, or oxyhydroxyls from, a typically aqueous, liquid medium. | 10-18-2012 |
20120261347 | NON-METAL-CONTAINING OXYANION REMOVAL FROM WATERS USING RARE EARTHS - The present disclosure is directed to the use of rare earth-containing additives, particularly rare earth-containing additives comprising rare earths of plural oxidation states, to remove non-metal-containing oxyanions. | 10-18-2012 |
20120261611 | RARE EARTH REMOVAL OF PHOSPHORUS-CONTAINING MATERIALS - This disclosure relates generally to methods and rare earth-containing additives for removing inorganic and organic phosphorus-containing target materials. | 10-18-2012 |
20130001094 | Lanthanide-Mediated Water Splitting Process for Hydrogen and Oxygen Generation - The application generally relates to a process for generating hydrogen, oxygen or both from water. More particularly, the application generally relates to a lanthanide-mediated electrochemical and/or photoelectrochemical process for generating hydrogen, oxygen or both from water. | 01-03-2013 |
