METHOD FOR PREPARING COMPOSITE CALCIUM CARBONATE THROUGH SOLUBILIZATION OF CARBON DIOXIDE OF COAL ASH FROM CIRCULATING FLUIDIZED BED POWER PLANT AND COMPOSITE CALCIUM CARBONATE PREPARED THEREBY
An embodiment of the present invention provides a method for preparing composite calcium carbonate through the solubilization of carbon dioxide of coal ash from a circulating fluidized bed power plant, the method comprising the steps of: immersing coal ash, generated from the circulating fluidized bed power plant, in water to prepare a mixture (step 1); injecting carbon dioxide into the prepared mixture to form calcium oxide in the coal ash into calcium carbonate (step 2); and subjecting the mixture, which has calcium carbonate formed therein, to solid-liquid separation (step 3).
Un mode de réalisation de la présente invention concerne une méthode de préparation de carbonate de calcium composite par solubilisation de dioxyde de carbone de cendres de charbon provenant d'une centrale électrique à lit fluidisé circulant, la méthode comprenant les étapes consistant à : immerger des cendres de charbon, générées à partir de la centrale électrique à lit fluidisé circulant, dans de l'eau pour préparer un mélange (étape 1); injecter du dioxyde de carbone dans le mélange préparé pour transformer de l'oxyde de calcium dans les cendres de charbon en carbonate de calcium (étape 2); et soumettre le mélange, qui a du carbonate de calcium formé à l'intérieur, à une séparation solide-liquide (étape 3).
