Abstract
A process is described for sequestering carbon dioxide. In the process, a carbonate, oxide or hydroxide of a divalent cation is reacted with the carbon dioxide and water and / or with a species resulting from the dissolution of the carbon dioxide in water, to form a hydrogen carbonate of the divalent cation. The carbonate, oxide or hydroxide of the divalent cation has a low solubility in water. The divalent cation of the hydrogen carbonate of the divalent cation thus formed is exchanged for a monovalent cation using an ion exchange medium, to produce a solution of a hydrogen carbonate of the monovalent cation.
Description
technical field [0001] The present invention relates to a method for the preparation of cationic halides, the use of the compounds thus prepared for the absorption of carbon dioxide, a method for the preparation of alkaline earth metal halides, a method for the absorption of carbon dioxide in the atmosphere, and the recovery of calcite, magnesite, dolomite from seawater stone and a variety of other compounds and substances. Background technique [0002] The excess carbon dioxide present in the atmosphere produced by burning fossil fuels is believed to be the main cause of global warming. In response to this problem, the carbon credit system is promoting efforts to absorb and absorb CO in the atmosphere 2 industries, the carbon credits can be compared with the production of CO 2 industry to trade. [0003] A major form of carbon sequestration that is rewarded with carbon credits is the cultivation of biomass, such as tree planting. However, carbon sequestration by this me...
