[0037] Furthermore, in describing the present invention, if it is determined that related publicly known techniques may obscure the gist of the present invention, detailed description thereof will be omitted.

[0038] The present invention will be described in detail below.

[0039] Extraction method for volatile substances from lunar soil The present invention provides a method for extracting volatile substances from lunar soil, which involves collecting frozen soil from the lunar regolith, heating it with a solar collector heater, and separating and storing the volatile substances from the soil.

[0040] The present invention provides a method for extracting volatile substances from lunar soil, comprising: (a-1) Collecting frozen lunar surface soil, heating it with a solar collector heater, and extracting and storing a mixed gas from the soil; (a-2) first analyzing and separating the mixed gas to store hydrogen, oxygen, and water; and (a-3) separating and storing the mixed gas into Group 0 gases such as Helium-3 and Helium-4 and carbon-based gases after primary analysis and separation of the mixed gas; The soil is obtained in the permanently shadowed areas of the Moon.

[0041] The present invention is innovative because it provides a method for extracting volatile substances from lunar soil, in which frozen soil from the lunar surface is collected, heated with a solar collector heater, and volatile substances are separated and stored from the soil, making it possible to live on the moon through this method of extracting volatile substances.

[0042] For humanity to survive, it is necessary to advance into space, and the moon and Mars are attracting attention as major targets for space exploration.

[0043] The moon is an outpost on the way to Mars, and the plan is to obtain space resources on the moon and then advance to Mars.

[0044] The space resources that we are trying to obtain on the moon include hydrogen, oxygen, water, helium, and carbon-based gases.

[0045] Therefore, through a long period of painstaking efforts and various research, the applicant has developed a method for extracting volatile substances from lunar soil, in which frozen soil is collected from the lunar surface, heated with a solar collector heater, and volatile substances are separated and stored from the soil, and a gas collection system using the same, thereby completing the present invention.

[0046] Here, the method for extracting volatile substances from lunar soil of the present invention may be a method for extracting volatile substances from lunar soil, which comprises collecting frozen lunar surface soil, heating it with a solar collector heater, and separating and storing the volatile substances from the soil.

[0047] In this case, in the step (a-1) of collecting frozen soil from the lunar surface soil, heating it with a solar collector heater, extracting and storing a mixed gas from the soil, The solar collector heater is a primary heat exchanger that converts solar energy into thermal energy and transfers it to a medium, and may include a reflector, a transparent cover, and a heat insulating material.

[0048] And the reflector of the solar collector heater may be an aluminum, glass or tempered glass reflector for solar heat collection.

[0049] In addition, in the step (a-1) of collecting frozen soil from the lunar surface soil, heating it with a solar collector heater, extracting and storing a mixed gas from the soil, When the frozen soil is heated by the solar collector heater, the frozen soil is heated, and the low-temperature gas contained in the voids in the soil or in the constituent materials of the soil is heated and extracted into a mixed gas, The extracted gas mixture can be stored in a chamber or container.

[0050] Here, the soil can be obtained in the permanently shadowed areas of the moon.

[0051] The soil can also be obtained from the lunar regolith.

[0052] Then, in the step (a-1) of collecting frozen soil from the lunar surface soil, heating it with a solar collector heater, extracting and storing a mixed gas from the soil, The components of the mixed gas may include hydrogen-based, helium-based, carbon-based, nitrogen-based, oxygen-based, sulfur-based, or chlorine-based gases.

[0053] By way of example, the gas mixture may include hydrogen, helium-3, helium-4, water, hydrogen sulfide, ammonia, sulfur dioxide, ethane, carbon monoxide, carbon dioxide, methanol, methane, ethanol, ethane, hydroxide ions, hydrogen chloride, and the like.

[0054] In addition, in the step (a-2) of primarily analyzing and separating the mixed gas and storing hydrogen, oxygen, and water, The mixed gas is analyzed by a mass spectrometer or a gas measuring device and separated by a membrane filter; The mass analyzer may be a quadrupole mass spectrometer.

[0055] Here, the mass spectrometer is an analyzer that measures gas extracted by heating the lunar soil and converts it into gaseous ions. The gaseous ions then have different currents and masses, so it may be an analysis device that can identify which molecules are present by measuring the ratio of their masses to charges.

[0056] The quadrupole mass spectrometer consists of four parallel metal rods. A voltage of +(U-Vcos(wt)) is applied to one pair of rods, and a voltage of -(U-Vcos(wt)) is applied to the other pair of rods. U is a DC voltage, and V is an AC voltage. In this way, the voltage applied to the four parallel rods affects the ion migration path. At a given DC or AC voltage, only ions with a certain m / z ratio pass through the quadrupole filter, while other ions are deviated from the path. Using this, ions passing through the quadrupole filter at various voltages are measured to obtain a mass spectrum. There are two ways to adjust the voltage: by varying the w value for fixed U and V values, or by varying the U and V values ​​for a fixed w value.

[0057] The mixed gas can also be separated using a membrane filter.

[0058] In the step (a-2) of primarily analyzing and separating the mixed gas and storing hydrogen, oxygen, and water, The mixed gas is first analyzed and separated to store hydrogen, oxygen, and water; the hydrogen is reduced with iron oxide to produce more water; The hydrogen can be further reacted with FeTiO3 to produce water.

[0059] Here, when the hydrogen is reduced with iron oxide (FeO) to further produce water, the reaction can be expressed by the following reaction formula (1).

[0060] H2+FeO→H2O+Fe ----- (1)

[0061] When the hydrogen is reduced with ilmenite (FeTiO3) to produce water, the reaction can be expressed by the following reaction formula (2).

[0062] H2+FeTiO3→H2O+Fe+TiO2---- (2)

[0063] In addition, the water and hydrogen are separated, and the hydrogen is reused for the next reduction reaction, and the water can be used to separate oxygen by electrolysis, and the hydrogen generated at this time can be further recycled.

[0064] Here, a method for producing water on the moon can use the hydrogen reduction reaction between the hydrogen and iron oxide or ilmenite (FeTiO3).

[0065] In particular, the ilmenite (FeTiO3) must be heated to produce water, and hydrogen may be necessary for the reaction.

[0066] At this time, the hydrogen begins to reduce with iron oxide or ilmenite (FeTiO3) at about 900°C, and oxygen gradually increases up to about 1400°C due to the electrolysis of water. From the total gas amount, oxygen accounts for about 25% or more, and hydrogen accounts for about 75%.

[0067] The amount of oxygen extracted is proportional to the iron (II) content, and when the iron content is about 20%, about 5% of oxygen can be produced.

[0068] In addition, in the step (a-3) of first analyzing and separating the mixed gas, and then separating and storing the Group 0 gases such as helium-3 and helium-4 and the carbon-based gases, The mixed gas is analyzed by a mass spectrometer or a gas measuring device and separated by a membrane filter; The mass analyzer may be a quadrupole mass spectrometer.

[0069] In the step (a-3) of first analyzing and separating the mixed gas, and then separating and storing the Group 0 gases such as Helium-3 and Helium-4 and the carbon-based gases, The Group 0 gas of helium-3 or helium-4 can be liquefied after separation and stored in a chamber or container.

[0070] In addition, in the step (a-3) of first analyzing and separating the mixed gas, and then separating and storing the Group 0 gases such as helium-3 and helium-4 and the carbon-based gases, the carbon-based gas comprises carbon monoxide, carbon dioxide, methanol, ethanol, methane, or ethane; The carbonaceous gas is separated and then stored in a chamber and a container; Hydrogen and oxygen can be added to the carbonaceous gas to further convert it to methane.
