A mixed gas such as hydrogen, carbon dioxide, and water vapor is generated, and a water gas conversion reaction is performed with or without adding water vapor to the mixed gas, and the resulting gas containing hydrogen, carbon dioxide, and water vapor is transferred to a deep sea. The present invention relates to a hydrogen production method characterized by pressurizing hydrogen into a container having an opening at the bottom through which seawater can flow, and collecting gas collected at the top of the container.

。The carbon source to be gasified is coal, heavy oil, etc. In addition, coke, charcoal, coal tar, etc. can also be used. The gasifying agent is oxygen, water vapor, etc. The gasification reaction may be similar to a known water gas reaction, and may be maintained at about 1000° C. or higher while feeding a gasifying agent in a known gas generating furnace. The gases produced include carbon monoxide, hydrogen, carbon dioxide, water vapor, etc.
このガスを必要により脱硫等の触媒毒除去処理を行ない
、次いで水性ガス転化反応させる。This gas is subjected to catalyst poison removal treatment such as desulfurization if necessary, and then subjected to a water gas conversion reaction.
水性ガス転化反応は酸化鉄一酸化クロム触媒、酸化亜鉛
一酸化クロム触媒等の水性ガス転化用触媒の存在下、２
００〜６００°Ｃ程度で反応させる。圧力は常圧であっ
てもよ（、反応容器を小型化し、あるいは反応速度を高
める目的で加圧してもよい。The water gas conversion reaction is carried out in the presence of a water gas conversion catalyst such as an iron oxide chromium monoxide catalyst or a zinc oxide chromium monoxide catalyst.
The reaction is carried out at about 00 to 600°C. The pressure may be normal pressure (or may be pressurized for the purpose of downsizing the reaction vessel or increasing the reaction rate.
この反応は平衡反応であるので水蒸気をさらに添加して
一酸化炭素の３倍モル以上、特に５倍モル以上としてお
くことが好ましい。Since this reaction is an equilibrium reaction, it is preferable to further add water vapor to make the amount of carbon monoxide 3 times or more, particularly 5 times or more, by mole.
水性ガス転化反応を行なわせたガスは深海に圧入する。The gas subjected to the water gas conversion reaction is injected into the deep sea.
深さは５００ｍより深くすることが好ましい。The depth is preferably greater than 500 m.
この深海には下部に海水が流通可能な開放部を有する容
器を設けておいて、そこに吹込む。この容器には送気ラ
インと排気ラインを接続してお（。A container with an opening at the bottom through which seawater can flow is installed in this deep sea, and the water is blown into it. Connect the air supply line and exhaust line to this container (.
容器の上部はガス溜として機能する。海中に吹き出させ
たガスは炭酸ガスを充分に溶解しうるよう、微気泡とな
るようにし、さらに上昇路をラセン状にするとか、邪魔
板を適宜設けることが好ましい。The top of the container acts as a gas reservoir. It is preferable that the gas blown into the sea be made into microbubbles so that carbon dioxide gas can be sufficiently dissolved, and that the ascending path be spiral-shaped or that baffles be provided as appropriate.
容器の上部に集まったガスは排気ラインを通って地上に
回収される。The gas that collects at the top of the container is returned to the ground through an exhaust line.
このガスは必要により深冷分離するなどしてさらに精製
し、水素ガスとして利用に供する。This gas is further purified by cryogenic separation, if necessary, and then used as hydrogen gas.
水性ガス転化反応させたガスを深海に吹き込むことによ
って炭酸ガスが臨界圧に近くなり、あるいは臨界圧を越
えて溶解度が高まり海中に溶解する。深海の水はほとん
ど上面に移動しない。そこで、炭酸ガスは深海に貯蔵さ
れることになり大気中の炭酸ガスを増加させない。By injecting the gas resulting from the water gas conversion reaction into the deep sea, the carbon dioxide gas approaches or exceeds the critical pressure, increasing its solubility and dissolving into the sea. Deep sea water rarely moves to the top. Therefore, carbon dioxide gas is stored in the deep sea and does not increase the amount of carbon dioxide gas in the atmosphere.
