摘要： Provided is a fixation method of carbon dioxide. The method includes a) grinding waste gypsum to become 200˜300 mesh; b) performing reaction by supplying mixed gas while mixing the ground waste gypsum with aqueous ammonia, and c) separating solid from liquid in the manufactured slurry by centrifugation and drying separated solid and liquid portions with calcite and ammonium sulfate, wherein the mixed gas is formed of nitrogen and carbon dioxide, and the carbon dioxide provides carbon dioxide fixation method containing 5˜25 wt %. When carbon dioxide is fixed by using waste gypsum, reaction efficiency is remarkably high. The fixation method makes more than 95% of supplied carbon dioxide fixed. Also, provided is an economical method that disposes carbon dioxide as a disposal target without its separation, refinement and liquefaction processes, to thereby remarkably reduce the entire process and costs for processes.
摘要翻译：提供二氧化碳的固定方法。该方法包括：a）研磨废石膏达到200〜300目; b）通过在将废弃石膏与氨水混合的同时供给混合气体进行反应，和c）通过离心并分离固体和液体部分与方解石和硫酸铵进行干燥分离制得的浆料中的固体，其中形成混合气体的二氧化碳，二氧化碳提供含有5〜25重量％的二氧化碳固定方法。当使用废石膏固定二氧化碳时，反应效率非常高。固定方式使95％以上的二氧化碳固定。此外，提供了在不进行分离，精制和液化过程的情况下将二氧化碳作为处置对象处理的经济方法，从而显着地减少了整个过程和工艺成本。
