The proposed invention uses industrial byproducts such as fly ash in an ion exchange/reverse osmosis (IE/RO) patented technology to sequester carbon dioxide CO2 gas and produce 6 to 7% sodium carbonate (Na2CO3) liquor. Similar materials encompass alkaline Fly Ash (AFA) liquor, alkaline red mud (ARM), coal ash, wood ash, and similar natural byproduct materials that are rich in metallic oxides. The process uses AFA or ARM at the input of an IE/RO process where the hydroxides (OH″) get extracted and concentrated for CO2 gas sequestration. The remaining insoluble byproduct material is used in civil works such as construction and road industry. Ion exchange modules are used to remove all multivalent ionic impurities while a reverse osmosis (RO) skid concentrates the carbonated liquor up to 6 to 7% liquor (or 10% in advanced RO). The process is not an electrochemical chloro-alkali battery nor related to the ammonical Solvay process. The invention is inherently harnessed for carbon capture in the production of soda chemicals from waste alkaline byproducts. There are similarities in the hardware of patent # WIPO Patent App. No. PCT/IB2009/007713. |

Disclosed is a method for solidifying carbon dioxide into carbonate, in which carbon dioxide is stably converted into and solidified into carbonate (mineral facies) by using steel slag or natural mineral by extracting an alkali component by supplying an ammonium salt solvent as an extraction solvent to raw slag and injecting carbon dioxide into an extract solution supplied to a carbonation reactor to produce carbonate precipitate from the extract solution through the induction of a conversion reaction of the carbon dioxide into the carbonate precipitate. Then after the above two step are performed at least one an acetic acid solvent is supplied as an extraction solvent to the raw slag so as to finally extract an alkali component; and carbon dioxide is injected into an extract solution to produce carbonate precipitate from the extract solution through the induction of a conversion reaction of the carbon dioxide into the carbonate precipitate. |

This invention describes a complete sequestration of carbon (CO2 and CO) from coal burning plants. In this process, hydrogen can be generated which in turn permits the reduction in the cost of hydride synthesis. The hydrides store hydrogen for on-board application for automobiles and fuel cells. Hydrogen generation and synthesis of hydrides is accomplished by using an integrated approach in which coal is used as a fuel and carbon is sequestered in the process. The CO and or CO2 produced in coal burning power plants and the heat is used when available for producing hydrogen and hydrides. Carbon is used both as a reactant and as a fuel. Economically hydrogen production cost is comparable to or less than the current price of hydrogen produced from fossil-fuel with the added benefit of carbon sequestration and reducing global warming. Specific processes for synthesizing important hydrogen storage materials, hydrides are described. A hydrogen based automobile becomes viable as the cost of the hydrogen production and hydride synthesis is reduced. Although coal-burning power plant is specified here, any power plant, coal- or natural gas-burning, can be subjected to similar treatment. |

The present invention relates to a method and process for recovering solid sodium bicarbonate, from the effluent, of the cathode compartment of a diaphragm cell that contains sodium hydroxide and sodium chloride. The effluent is treated with carbon dioxide and ammonia to essentially convert the sodium hydroxide to sodium bicarbonate. Thereafter, the effluent is treated to decompose the ammonium chloride to evolve and recycle ammonia without the formation of pollutants, the treated effluent, free of NH.sub.3, CO.sub.2 and alkali, is resaturated and sent to the anode compartment of the diaphragm cell. In preferred embodiments, all of the steps are interconnected and the materials produced are recycled, such that the only products produced are chlorine, hydrogen and sodium bicarbonate, without waste products in a continuous process. |

The present invention is directed to an improved method for carrying out a exothermic chemical reaction with carbon dioxide in an aqueous environment. In the method, a fluid solution containing at least one chemical reactant which is exothermically reactive with carbon dioxide is provided. Liquid carbon dioxide is then injected into the solution of the chemical reactant at a pressure above the triple point of at least about 60 psig. The injection of the liquid carbon dioxide takes place under turbulent conditions wherein the liquid carbon dioxide expands to provide carbon dioxide vapor. The carbon dioxide vapor superheats to approach the exothermic reaction temperature which occurs between the carbon dioxide vapor and the chemical reactant. The chemical reactant and the carbon dioxide react in the dispersion exothermically to produce a chemical reaction product. The flow rate of liquid carbon dioxide can be controlled to control the reaction temperature without the encessity for providing any reactor cooling or heat exchange apparatus. |
