| 252193000 | AMMONIA, ALKALI OR BASE, BINDANT CONTAINING | 10 |
| 20100155660 | MIXTURES OF AMMONIA AND IONIC LIQUIDS - Mixtures of ammonia and ionic liquids are provided that are suitable for use as absorption cooling fluids in absorption cycles, and ammonia storage. | 06-24-2010 |
| 20110073806 | CONNECTED HEAT CONDUCTING STRUCTURES IN SOLID AMMONIA STORAGE SYSTEMS - A compacted block of material constructed of one or more units consisting of matter comprising an ammonia-saturated material capable of reversibly desorbing and ad- or absorbing ammonia surrounded by a gas-permeable, flexible material having a thermal conductivity of at least five times the thermal conductivity of said ammonia-saturated material at −70° C. to 250° C. and methods for producing the same are described. | 03-31-2011 |
| 20140097382 | Process for Preparing Crosslinked Polymer-Carbon Sorbent - A polymer-carbon sorbent for removing at least one of carbon dioxide, heavy metals or toxic materials from a flue gas from a combustion process, such as coal-fired power plants, is described. The sorbent comprises a carbonaceous sorbent material and a cured amine-containing polymer, and sulfur. The polymer-carbon sorbents are formed by curing a curable amine-containing polymer in the presence of the carbonaceous sorbent material, sulfur, a cure accelerator and, optionally, a cure activator. A convenient carbonaceous sorbent material is an activated carbon, and a convenient curable amine-containing polymer is an allyl-containing poly(ethyleneimine), having a number average molecular weight between about 1,000 and about 10,000. The polymer-carbon sorbents may contain sulfur in molar excess of an amount needed to cure the curable amine-containing polymer. Such polymer-carbon sorbents are shown to capture more mercury, in both elemental an ionic forms, compared to activated carbon and adsorb carbon dioxide. | 04-10-2014 |
| 20140145111 | CONTROL OF MERCURY EMISSIONS - Methods for controlling mercury emissions and/or reducing corrosion of equipment used in combustion processes are provided, and more particularly, methods for controlling mercury re-emissions from a wet flue gas desulfurizer and/or reducing corrosion of the wet flue gas desulfurizer. | 05-29-2014 |
| 20140239224 | Sorbent for Lithium Extraction - This invention relates to a method for preparing a lithium aluminate intercalate (LAI) matrix solid and methods for the selective extraction and recovery of lithium from lithium containing solutions, including brines. The method for preparing the LAI matrix solid includes reacting aluminum hydroxide and a lithium salt for form the lithium aluminate intercalate, which can then be mixed with up to about 25% by weight of a polymer to form the LAI matrix. | 08-28-2014 |
| 20140264166 | PHENOXYPYRAZOLE COMPOSITION AND PROCESS FOR THE SOLVENT EXTRACTION OF METALS - Metal extractants of 2-hydroxyphenyldiazole compounds according to Formula (2): | 09-18-2014 |
| 20140306154 | Freezer/Fridge Mats - Freezer/Fridge Mats, is a line absorbent, odor absorbing and disposable mats that are easily applied to refrigerator and freezer shelves and drawers to easily and effectively maintain a clean and sanitary refrigerator. Freezer Fridge Mats are manufactured with an absorbent sanitary paper material or comparable biodegradable synthetic blend. Each Freezer Fridge Mats is rectangular in shape and is perforated and easily cut to fit various size drawers and shelving. Freezer Fridge Mats are infused with baking soda to absorb odors and provide optimal refrigerator and freezer freshness. | 10-16-2014 |
| 20140374655 | METHODS FOR MITIGATING THE LEACHING OF HEAVY METALS FROM ACTIVATED CARBON - Compositions, methods, and systems for reducing leaching of heavy metals from sorbents having adsorbed heavy metals are described herein. Such compositions and methods may include reducing agents. | 12-25-2014 |
| 20150060729 | METHOD FOR PRODUCING A SULPHIDED COPPER SORBENT - A method for producing a sulphided copper sorbent includes the steps of: (i) contacting a sorbent precursor material containing one or more sulphidable copper compounds, with a sulphiding gas stream including hydrogen sulphide to form a sulphided sulphur-containing sorbent material, and (ii) subjecting the sulphided sulphur-containing sorbent material to a heating step in which it is heated to a temperature above that used in the sulphiding step and ≧110° C., under an inert gas selected from nitrogen, argon, helium, carbon dioxide, methane, and mixtures thereof, the inert gas optionally including hydrogen sulphide. The method provides sulphided copper sorbents that have reduced levels of elemental sulphur. | 03-05-2015 |
| 20150343378 | CATALYTICALLY ENHANCED COMPOSITIONS FOR EFFICIENT REMOVAL OF CONTAMINANTS IN FLUE GAS STREAMS - A sorbent composition that is useful for injection into a flue gas stream of a coal burning furnace to efficiently remove mercury from the flue gas stream. The sorbent composition may include a sorbent with an associated ancillary catalyst component that is a catalytic metal, a precursor to a catalytic metal, a catalytic metal compound or a precursor to a catalytic metal compound. Alternatively, a catalytic metal or metal compound, or their precursors, may be admixed with the coal feedstock prior to or during combustion in the furnace, or may be independently injected into a flue gas stream. A catalytic promoter may also be used to enhance the performance of the catalytic metal or metal compound. | 12-03-2015 |
