Abstract:	本發明關於一種二氧化碳捕集與利用之處理方法，其利用氫氧化鉀(KOH)對二氧化碳之高溶解度。先將二氧化碳送入含有氫氧化鉀溶液之吸收塔內，藉以形成碳酸鉀，再導入流體化床結晶槽來與鈣離子(或鎂離子、或鋇離子)反應形成碳酸鈣(或碳酸鎂、或碳酸鋇)結晶顆粒，藉此將二氧化碳捕集下來。此外，結晶槽中的鉀離子再以KOH的形式迴流至該吸收塔，回收再使用。是以，本發明得以避免額外製造環境污染外，還能產製化學品提供利用，進而增加額外的收益。再者，本發明更提供一種二氧化碳捕集與利用之裝置用於本發明的處理方法。 The present invention relates to a treatment method for carbon dioxide capture and utilization, which utilizes the high solubility of carbon dioxide in KOH solution. The carbon dioxide is firstly absorbed in a solution containing KOH to form potassium carbonate in an absorption tower and then introduced into a fluidized bed crystallization tank to react with calcium, magnesium or barium ions to produce crystalline particles of calcium carbonate, magnesium carbonate, or barium carbonate for capturing the carbon dioxide . Furthermore, potassium ions in the crystallization tank are recycled to the absorption tower for reuse. Therefore, the present invention can avoid the additional environmental pollution, and can produce chemicals for reused, which increases additional benefits. In addition, the present invention further provides a device for carbon dioxide capture and utilization for the treatment method of the present invention.
