Zusammenfassung:	To provide a technology capable of obtaining CO2 containing almost no H2.SOLUTION: A disclosed method comprises: (a) liquefying supercritical water by cooling a high-temperature, high-pressure fluid containing supercritical water, CO2, and H2, and separating liquid water from the fluid; (b) liquefying CO2 by cooling the fluid from which the liquid water has been separated, and separating the liquefied CO2 from the fluid; and (c) producing dry ices by releasing the liquefied CO2 into the air.SELECTED DRAWING: Figure 1 【課題】Ｈ２をほぼ含まないＣＯ２を得ることができる技術を提供する。【解決手段】開示された方法は、（ａ）超臨界水とＣＯ２とＨ２とを含む高温高圧の流体を冷却することによって超臨界水を液化し、流体から液水を分離する工程と、（ｂ）液水が分離された流体を冷却することによってＣＯ２を液化し、流体から液化ＣＯ２を分離する工程と、（ｃ）液化ＣＯ２を空気中に放出することによってドライアイスを生成する工程と、を備える。【選択図】図１
