| 20080276677 | System and method for carbon dioxide double sequestration - A climate control system capable to absorb many times the human-industrial-generated carbon dioxide and reverse the trend of global warming is described in this invention. Method of partially executing Solvay soda ash process without converting sodium bicarbonate to soda ash and recycling ammonia, further thereafter implementing ammonium chloride thus obtained as deep-water ocean fertilizer to capture carbon dioxide naturally in weights of the order of hundred times that was originally released through fossil fuel combustion. | 11-13-2008 |
| 20120137744 | ACID-IMPREGNATED ACTIVATED CARBON AND METHODS OF FORMING AND USING THE SAME - An acid-impregnated activated carbon matrix is formed from a carbonaceous material by the addition of a mineral acid, and may be used to chemisorb ammonia from a gas stream. The ammonia reacts with the acid to form a fertilizer salt. The spent matrix may be used as a fertilizer, or the fertilizer salt may be elutriated from the matrix. | 06-07-2012 |
| 20120204613 | METHOD AND APPARATUS FOR INCINERATING WASTE - The invention provides a method and apparatus for incinerating waste, wherein the waste is one or more of an organic waste and an inorganic waste. The apparatus includes a grinder for grinding a mixture of the waste and calcium carbonate. The ground mixture is then fed to a molten metal bath contained within a crucible. Thereafter, a heating member configured proximal to the crucible combusts the mixture of the waste and the calcium carbonate to form one or more of slag and one or more acidic gases. On combustion, the one or more acidic gases are neutralized by calcium hydroxide produced as a result of combusting the calcium carbonate. Additional metal compounds usable as fertilizers are also produced in response to reacting with the one or more acidic gases. | 08-16-2012 |
| 20120240650 | STABILIZATION AND REMOTE RECOVERY OF ACID GAS FRACTIONS FROM SOUR WELLSITE GAS - A method for the recovery of hydrogen sulphide and other acid gas fractions from sour wellsite gas in hydrocarbon production is provided. The selected acid gas fractions are absorbed into a noncorrosive and transportable solvent solution at the wellsite, the rich solvent solution being transported to a central plant location where it is desorbed from the solvent solution for further handling or processing. The lean solvent solution can then be recycled. Multiple acid gas fractions could be recovered from the sour gas in question using a single appropriate solvent solution. Carbon dioxide could be absorbed and desorbed at the wellsite rather than at the central plant location. Clean gas is yielded at the natural gas into solvent wellsite for downstream processing or sale. | 09-27-2012 |
| 20150033812 | Methods and Systems for the Co-Generation of Gaseous Fuels, Biochar, and Fertilizer From Biomass and Biogenic Wastes - Methods and systems for converting a biomass and biogenic wastes to hydrogen with integrated carbon dioxide capture and storage are disclosed. In some embodiments, the methods include the following: mixing at least one of a dry solid or liquid or liquid hydroxide and catalysts with a biomass to form a biomass mixture; heating the biomass mixture until the hydroxide and the biomass react to produce hydrogen, carbonate, biochar, and potentially fertilizer; calcining the carbonate or performing double replacement reactions of the carbonate to produce sequestration-ready carbon dioxide and a hydroxide; storing the carbon dioxide produced; transferring the hydrogen produced to a fuel cell; and generating electricity with the fuel cell. | 02-05-2015 |
| 20150344363 | Titanium-Containing Aggregate, Method for its Manufacture, and Use Thereof - The invention concerns a titanium-containing aggregate obtainable by mixing and/or treating residues from the manufacture of titanium dioxide which are obtained during the manufacture of titanium dioxide using the sulphate and/or chloride process with basic slags from the manufacture of metals, a method for its manufacture and its use in metallurgical processes, as well as its use as an aggregate and/or filler for concrete, cement, asphalt, refractory materials, repair compounds and sizes. | 12-03-2015 |
