A reactor is filled with hydrogen prior to a reaction, and liquid sodium and water vapor are injected into the reactor; when the water vapor comes into contact with the liquid sodium, a combustion reaction occurs to generate hydrogen and sodium hydroxide, and the water vapor which does not participate in the reaction absorbs heat to form high-temperature water vapor having a higher temperature; the temperature of a gas mixture of the hydrogen and the high-temperature water vapor is lower than 70°C after passing through a heat exchanger, the high-temperature water vapor is condensed into water and flows back to the bottom of the reactor, and the hydrogen is discharged from a hydrogen collecting pipe via a pressure relief valve; and a drain valve is controlled during the combustion reaction, and the height of a sodium hydroxide solution is made to be lower than the outlet end of a water vapor injection pipe. Potential safety hazards such as explosions caused by the reaction of sodium with water in the prior art are avoided, a heat source having a relatively high temperature and hydrogen can be formed, and the operation cost is reduced.

Resumen de: WO2025096690A1
A cyclic process for the capture of carbon dioxide (CO2) directly from air utilizing a three-compartment electrolytic cell coupled with a hydroxide-based CO2 capture system as well as a carbonate-based CO2 capture system. Air is passed over a hydroxide compound in the hydroxide-based CO2 capture system to extract carbon dioxide from the air and produce a carbonate compound which is transferred to the carbonate-based CO2 capture system, where air is passed over the carbonate compound to extract carbon dioxide from the air and produce a bicarbonate compound. The bicarbonate is then passed into the three-compartment electrolytic cell where CO2, hydrogen and oxygen gases are separately released and the bicarbonate solution is transformed into a hydroxide solution that is reused in the hydroxide-based CO2 capture system. The flow of input compounds from one system to the other enables efficient operation of the direct air capture of carbon dioxide system.
