Description

액체금속을 이용한 온실가스 저감 장치 및 이의 작동방법Greenhouse gas reduction device using liquid metal and its operation method
본 발명은 액체금속을 이용한 온실가스 저감 장치 및 이의 작동방법에 관한 것으로, 보다 상세하게는 다종의 온실가스를 동시에 다량으로 제거하기 위한 액체금속을 이용한 온실가스 저감 장치 및 이의 작동방법에 관한 것이다.The present invention relates to a greenhouse gas reduction device using a liquid metal and an operating method thereof, and more particularly, to a greenhouse gas reduction device using a liquid metal and an operating method thereof for simultaneously removing a large amount of various types of greenhouse gases.
CO2를 이용해 자원을 생산하는 기술은 CCU(Carbon capture and utilization) 기술 범주에 속하며, CO2를 이용해 탄소와 산소를 생산하는 기술은 온실가스 저감이 필요한 모든 산업군에 필요한 기술이다.The technology for producing resources using CO 2 belongs to the category of CCU (Carbon capture and utilization) technology, and the technology for producing carbon and oxygen using CO 2 is a necessary technology for all industries that require greenhouse gas reduction.
특히 이산화탄소 배출이 문제가 되고 있는 발전, 제철, 정유 및 석유화학 산업 및 화석연료를 사용하는 수송산업 전반에서 관련 수요가 증가하고 있으며, 이산화탄소 처리 과정에서 생산된 산소는 산업용, 의료용, 발전용 등 다양한 산소이용 분야에 활용이 가능하고 탄소 역시 고부가 소재로 활용 가능한 장점이 있다. In particular, demand is increasing in power generation, steelmaking, oil refining, and petrochemical industries, where carbon dioxide emission is a problem, and transportation industries that use fossil fuels. It can be used in the field of oxygen utilization, and carbon can also be used as a high value-added material.
이러한 CO2를 이용한 자원 생산 기술은 주로 CO2와 다른 물질과의 반응을 통해 탄소 화합물이나 탄화수소계열 물질을 생산하는 기술이 대부분이다.Resource production technologies using CO 2 are mostly technologies for producing carbon compounds or hydrocarbon-based materials through a reaction between CO 2 and other materials.
일 예로, CO2를 고순도화한 이후에 100기압 이상으로 압축하여 저장하는 CCS(carbon capture and storage) 기술, CO2를 광물화하여 저장하는 CO2 광물화 기술, 기화학적 CO2 전환을 통해 개미산 등 탄소가 포함된 화학원료를 생산하는 탄소 포함 소재 생산 기술, 공기중의 산소를 분리하는 ASU(Air Separation unit) 기술, 고체 탄화수소 내 고정탄소를 분리하는 열분해나 기체 및 액체 탄화수소의 열화학적 반응을 통해 탄소를 생산하는 기술, 전기화학(electrochemical) 방식을 통해 CO2를 분해하는 전기분해 기술 등이 있다.For example, carbon capture and storage (CCS) technology for compressing and storing CO 2 at a pressure of 100 atmospheres or more after highly purifying CO 2 , CO 2 mineralization technology for mineralizing and storing CO 2 , and formic acid through gaseous chemical CO 2 conversion Carbon-containing material production technology that produces chemical raw materials containing carbon, etc., ASU (Air Separation unit) technology that separates oxygen in the air, pyrolysis that separates fixed carbon from solid hydrocarbons, or thermochemical reactions between gas and liquid hydrocarbons. There is a technology for producing carbon through carbon production, an electrolysis technology for decomposing CO 2 through an electrochemical method, and the like.
그러나 이러한 종래의 기술들은 다종의 온실가스(CO2, F-gas, NF3, SF6, CF4 등)를 동시에 다량으로 제거하기 어려운 한계가 있었다.However, these conventional technologies have limitations in that it is difficult to simultaneously remove a large amount of various greenhouse gases (CO 2 , F-gas, NF 3 , SF 6 , CF 4 , etc.).
구체적으로, 온실가스의 종류에는 직접 온실가스와 간접온실가스가 있다. 직접 온실가스는 온실효과에 직접 기여하는 물질들로서, 이산화탄소, 육불화황과 같은 과불화화합물이 있다. 그리고, 간접온실가스는 다른 물질과 반응하여 온실가스로 전환될 수 있는 물질로서, 질소산화물 및 황산화물과 같은 물질들이 있다. 종래의 기술들만으로는 이러한 직접 온실가스와 간접 온실가스들을 동시에 저감하기 어려운 문제가 있었다.Specifically, the types of greenhouse gases include direct greenhouse gases and indirect greenhouse gases. Direct greenhouse gases are substances that directly contribute to the greenhouse effect, and include perfluorinated compounds such as carbon dioxide and sulfur hexafluoride. Indirect greenhouse gases are substances that can be converted into greenhouse gases by reacting with other substances, and include substances such as nitrogen oxides and sulfur oxides. There was a problem in that it is difficult to simultaneously reduce these direct greenhouse gases and indirect greenhouse gases with only conventional technologies.
또한 종래의 기술은 매우 안정한 분자에 해당하는 CO2의 환원 및 분해시 전환율이 낮아 경제적이지 못하기 때문에 상용화가 어려운 문제가 있었다.In addition, the conventional technology has a problem in commercialization because it is not economical because the conversion rate during reduction and decomposition of CO 2 corresponding to a very stable molecule is low.

도 2 내지 도 4는 본 발명의 일실시예에 따른 액체금속 온도, 반응 시간에 따른 이산화탄소, 일산화탄소, 탄소 및 산소의 변화를 나타낸 그래프이다. 2 to 4 are graphs showing changes in carbon dioxide, carbon monoxide, carbon and oxygen according to liquid metal temperature and reaction time according to an embodiment of the present invention.
도 2 내지 도 4를 참고하면, 원료가 이산화탄소이고 액체금속이 액체주석일 경우, 액체주석의 온도 변화에 따라 화학식1과 같은 반응이 주로 이루어진다. 이 반응은 고온 영역에서 우세하며 액체주석의 일부가 산화되면서 이산화탄소를 환원시켜 일산화탄소를 발생시킨다. 도 5는 본 발명의 일실시예에 따른 온도에 따른 이산화탄소의 저감률을 나타낸 그래프이다. 최대저감률은 원료 공급 및 반응 조건에 따라 변동(상향)될 수 있다.Referring to FIGS. 2 to 4, when the raw material is carbon dioxide and the liquid metal is liquid tin, the reaction shown in Formula 1 is mainly performed according to the temperature change of the liquid tin. This reaction is dominant in the high-temperature region, and a part of the liquid tin is oxidized to reduce carbon dioxide to generate carbon monoxide. 5 is a graph showing the reduction rate of carbon dioxide according to temperature according to an embodiment of the present invention. The maximum reduction rate may vary (increase) depending on raw material supply and reaction conditions.
[화학식1][Formula 1]
Sn + CO2 → SnO + COSn + CO 2 → SnO + CO
원료가 이산화탄소이고 액체금속이 액체주석일 경우, 도 2의 저온영역 에서의 결과와 같이 액체주석과 이산화탄소의 반응은 아래 화학식 2와 같이 탄소를 반응물로 생성시킬 수 있다. When the raw material is carbon dioxide and the liquid metal is liquid tin, as shown in the low-temperature region of FIG. 2, the reaction between liquid tin and carbon dioxide can produce carbon as a reactant as shown in Formula 2 below.
[화학식2][Formula 2]
2Sn + CO2 → SnO2 + C 2Sn + CO 2 → SnO 2 + C
2Sn + CO2 → 2SnO + C 2Sn + CO 2 → 2SnO + C
원료가 이산화탄소이고 액체금속이 액체주석일 경우, 액체주석의 온도, 반응물의 양과 체류시간의 조절을 통해 상기 화학식 1, 2를 포함한 overall 화학식3의 반응이 이루어 진다. 이때 반응 조건을 변화시키거나 서로 다르 조건의 다단 반응을 조합하여 원하는 생성물을 선택적으로 얻을 수 있다. When the raw material is carbon dioxide and the liquid metal is liquid tin, the reaction of the overall formula 3 including the above formulas 1 and 2 is performed by adjusting the temperature of the liquid tin, the amount of the reactant, and the residence time. At this time, a desired product can be selectively obtained by changing the reaction conditions or by combining multiple reactions under different conditions.
[화학식3][Formula 3]
aSn(L) + bCO2 → cSn(L) + dSnO2(S) + eSnO(S) + fC + gCO +hO2 + iCO2 aSn(L) + bCO 2 → cSn(L) + dSnO 2 (S) + eSnO(S) + fC + gCO +hO 2 + iCO 2
이처럼, 액체주석의 온도가 용융점(예를들어300도) 이상일 때부터 이산화탄소의 분리가 이루어지며, 온도 영역에 따라 이산화탄소가 분리되어 생상되는 생성물이 달라지는 것을 알 수 있다.As such, it can be seen that carbon dioxide is separated from when the temperature of liquid tin is higher than the melting point (eg, 300 degrees), and the product produced by separating carbon dioxide varies depending on the temperature range.
따라서, 상기 제어부(170)는 상기 측정부(160)와 연계하여 상기 액체주석의 온도를 조절함으로써 산소, 일산화탄소, 탄소의 생성에 따른 농도 비율을 조절하도록 마련될 수 있다.Therefore, the control unit 170 may be provided to adjust the concentration ratio according to the generation of oxygen, carbon monoxide, and carbon by controlling the temperature of the liquid tin in association with the measurement unit 160.
도 5는 본 발명의 일실시예에 따른 온도에 따른 이산화탄소의 저감률을 나타낸 그래프이다. 최대저감률은 원료 공급 및 반응 조건에 따라 변동(상향)될 수 있다. 5 is a graph showing the reduction rate of carbon dioxide according to temperature according to an embodiment of the present invention. The maximum reduction rate may vary (increase) depending on raw material supply and reaction conditions.
이처럼 마련된 본 발명은 이산화탄소와 같은 온실 가스를 상분리하여 고부가 가치의 고순도 산소, 탄소 및 일산화탄소를 생성하도록 할 수 있다.The present invention prepared as described above can phase-separate greenhouse gases such as carbon dioxide to generate high-purity oxygen, carbon, and carbon monoxide of high added value.
한편, 본 발명에서 상기 원료가 육불화황과 같은 과불화 화합물인 경우, 상기 반응부에서는 하기 화학식 4와 같은 반응이 일어날 수 있다.Meanwhile, in the present invention, when the raw material is a perfluorinated compound such as sulfur hexafluoride, a reaction shown in Chemical Formula 4 may occur in the reaction unit.
