본 발명은 수성가스전환 반응 촉매용 활성성분; 및 이산화탄소 흡수용 활성성분을 포함하는 하이브리드 입자 및 그 제조 방법에 관한 것이다. The present invention is an active ingredient for water gas shift reaction catalyst; And it relates to a hybrid particle and a method for producing the same comprising an active ingredient for carbon dioxide absorption.

지구온난화로 인한 기후변화의 발생에 따라 상기 기후변화에 대한 대응이 국제 및 국내의 최우선 의제로 부상하고 있다. 세계 각국은 기술개발을 통해 자국의 온실가스를 감축하는 방안을 확보하여 신 성장 동력 창출 및 세계시장 선점의 노력을 지속하고 있다. IEA(2006) 보고서에서는, 2050년 전세계 에너지 소비의 70% 이상이 화석연료이며, 향후 석유의 고갈에 따라 석탄의 비중이 지속적으로 증가할 것으로 예상하고 있다. In response to the occurrence of climate change due to global warming, the above-mentioned response to climate change has emerged as a high priority for the international and domestic. Countries around the world have secured ways to reduce their own greenhouse gases through technology development, creating new growth engines and preoccupying the global market. According to the IEA (2006) report, more than 70% of global energy consumption in 2050 is fossil fuels, and the proportion of coal will continue to increase as oil runs out.

화석연료의 사용을 지속하면서 경제성장을 견인할 수 있는 대안으로는, 화석연료의 사용 시 발생하는 CO2를 포집하여 저장하는 기술(CCS; Carbon Capture and Storage)이 있다. 2006년 IEA에서 발표한 대기 중 CO2를 줄이기 위한 시나리오에 따르면, 상기 CCS 기술은 산업과 발전 부문에서 이산화탄소를 20% 이상 줄일 수 있는 기술로 평가하고 있으며, 현재 전세계적으로 CCS 기술개발이 추진되고 있다. An alternative to driving economic growth while continuing to use fossil fuels is carbon capture and storage (CCS), a technology that captures and stores CO 2 from fossil fuel use. According to the scenario for reducing CO 2 of the announcement Waiting in the 2006 IEA, the CCS technology is evaluated as a technology that can reduce carbon dioxide by more than 20% in the industrial and power generation sectors, the current worldwide CCS technology is being pursued have.

상기 CCS 기술에는 연소 전, 연소 중 및 연소 후 기술이 있으며, 이들 중 연소 전 CO2 포집 기술은 다양한 화석연료를 부분산화(가스화)시켜 수소 및 일산화탄소가 주성분인 합성가스를 제조하고, 수성가스전환반응을 통해 수소 및 이산화탄소로 전환한 후 상기 수소 및 이산화탄소를 분리하는 기술이다. 상기 기술은 합성가스를 다양한 응용분야(연료전지 기술, 석탄 액화 기술, 화합물 제조 등)에 이용하기 전에 이산화탄소를 포집하는 기술이다. 연소 전 이산화탄소 포집 기술은 석탄, 바이오 매스 및 유기 폐기물 등을 원료로 이용할 수 있어 석유고갈 및 고유가에 대비할 수 있으며, 생성물인 합성가스는 발전, 연료전지, 합성원료 생산 등 다양하게 활용할 수 있다. 또한, 고온, 고압에서 CO2를 회수 할 수 있어 기술 적용에 따른 효율저감을 줄일 수 있고, 압축비용을 낮출 수 있어 CO2 포집비용의 저감 잠재성이 큰 기술이다. The CCS technology includes pre-combustion, in-combustion and post-combustion technologies, among which CO 2 capture technology partially oxidizes (gasifies) various fossil fuels to produce a synthesis gas mainly composed of hydrogen and carbon monoxide, and converts water gas. After converting the hydrogen and carbon dioxide through the reaction is a technique for separating the hydrogen and carbon dioxide. The technique is a technique for capturing carbon dioxide before using the synthesis gas for various applications (fuel cell technology, coal liquefaction technology, compound production, etc.). The pre-combustion carbon dioxide capture technology can use coal, biomass and organic waste as raw materials to prepare for oil depletion and high oil prices, and the synthesis gas as a product can be utilized in various ways such as power generation, fuel cells, and synthetic raw materials production. In addition, high temperature, and it is possible to recover the CO 2 at a high pressure can reduce the efficiency reduction of the technology, it is possible to lower the cost of compressing the large reduction potential of the CO 2 capture technology costs.

상기 연소 전 CO2 포집 기술에는 PSA 공정 및 Selexol, Rectisol과 같은 습식 물리흡수제를 이용하는 기술 및 막분리 기술이 있다. PSA 공정 및 Selexol, Rectisol 등의 물리흡수제를 이용하는 기술은, 낮은 온도에서 운전되기 때문에 열효율이 낮고 높은 재생에너지가 필요하여 에너지 소비가 높다는 문제점이 있다. 특히 기존 상용 습식공정은 2단 수성가스전환(WGS), 열교환, 저온 CO2 흡수 등 최소 4단 이상의 공정 구성이 필요하고, 회수된 CO2의 압력이 낮아 저장 등을 위해 2단 이상의 압축이 필요하다. 또한, CO2가 제거된 연료가스의 온도가 낮아 가스터빈 전단에서 재 가열에 따른 비용 및 효율 손실이 크다. The pre-combustion CO 2 capture technique includes a technique using a PSA process and a wet physiological absorber such as Selexol and Rectisol, and a membrane separation technique. The technology using the PSA process and physical absorbents such as Selexol and Rectisol has a problem of low energy efficiency and high energy consumption due to low thermal efficiency and high energy consumption. In particular, the existing commercial wet process requires at least four stages of process configuration, such as two-stage water gas conversion (WGS), heat exchange, and low temperature CO 2 absorption, and requires at least two stages of compression for storage due to low pressure of recovered CO 2 . Do. In addition, since the temperature of the fuel gas from which CO 2 is removed is low, the cost and efficiency loss due to reheating at the front of the gas turbine are high.

막분리 기술의 경우 고압에서 운전이 가능하여 에너지 효율이 높으나, 처리용량이 작아 대규모 산업공정에 적용하기엔 한계가 있다.Membrane separation technology has high energy efficiency because it can be operated at high pressure, but there is a limit to apply to large industrial process due to its small capacity.

가스화기에서 생성된 합성가스의 고온 고압 조건을 유지하면서 효과적으로 CO2를 포집, 분리할 수 있는 기술로 촉진수성가스전환(SEWGS; Sorption Enhanced Water Gas Shift) 공정이 있다. 상기 기술은 수성가스전환(WGS) 반응과 동시공정으로 CO 전환율 향상을 촉진시킬 수 있으며, 재생 시 고농도의 CO2만을 분리할 수 있어 무공해 청정에너지 사용을 목표로 하는 연소 전 CO2 포집 기술로 적용 가능하다. Sorption Enhanced Water Gas Shift (SEWGS) is a technology that can effectively capture and separate CO 2 while maintaining the high temperature and high pressure conditions of the syngas produced in the gasifier. This technology can promote CO conversion rate by simultaneous process with water gas conversion (WGS) reaction, and can be separated into high concentration of CO 2 during regeneration, and applied as pre-combustion CO 2 capture technology aiming to use clean energy. It is possible.

천연가스의 개질 후 CO2를 회수하는 고정층 SEWGS 공정 개발이 유럽에서 진행되고 있으나, 최고 7단계의 공정으로 구성되어 있어 운전이 복잡하며, 연속 운전이 용이치 않아 IGCC와 같은 대규모 산업공정의 연소전 이산화탄소 회수처리에는 한계가 있다.The development of a fixed bed SEWGS process that recovers CO 2 after natural gas reforming is underway in Europe, but is composed of up to seven stages of operation, which makes the operation complicated and difficult to operate continuously, leading to the pre-combustion of large industrial processes such as IGCC. Carbon dioxide recovery is limited.

이에 비해 유동층 SEWGS 공정은 전환/흡수-재생 과정의 One-loop 공정이 가능하며, 대용량 CO2 회수처리에 적합하다. In comparison, the fluidized bed SEWGS process is capable of a one-loop process of conversion / absorption-regeneration and is suitable for large-capacity CO 2 recovery.

상기 유동층 촉진수성가스전환 기술은 유동층 반응기로 구성된 2개의 반응기 사이를 흡수제와 촉매가 연속적으로 순환하며, 첫 번째 반응기에서는 일산화탄소 전환반응과 동시에 이산화탄소 포집반응이 진행되어 고농도의 수소를 생산하고, 두 번째 반응기에서는 이산화탄소를 포집한 흡수제가 수증기와 추가의 열원에 의해 재생되어 고농도의 이산화탄소를 분리할 수 있다. 촉매와 흡수제는 두 반응기를 연속, 반복적으로 순환하므로 연속공정이 가능하여 석탄가스화 복합발전 등 대규모 산업공정에 적용하기 용이하다. 이 기술은 고체입자를 사용하므로 폐수가 거의 발생하지 않고, 부식문제가 적으며, 저가의 다양한 소재 사용이 가능하다. 또한, 흡수제는 재생하여 반복 사용 가능하므로 미래 저비용 이산화탄소 회수 및 수소생산 기술로도 활용 잠재성이 큰 기술 이다.In the fluidized bed accelerated water gas conversion technology, the absorbent and the catalyst are continuously circulated between two reactors composed of a fluidized bed reactor, and the first reactor produces a high concentration of hydrogen by performing a carbon dioxide capture reaction simultaneously with a carbon monoxide conversion reaction. In the reactor, absorbents that capture carbon dioxide can be regenerated by water vapor and additional heat sources to separate high concentrations of carbon dioxide. The catalyst and the absorbent circulate the two reactors continuously and repeatedly, so that the continuous process is possible, making it easy to apply to large industrial processes such as coal gasification combined cycle power generation. This technology uses solid particles, so there is little waste water, less corrosion problems, and it is possible to use various inexpensive materials. In addition, since the absorbent can be regenerated and used repeatedly, it is a technology having great potential for use as a future low-cost carbon dioxide recovery and hydrogen production technology.

Here, the content of the solid raw material was about 26.2 parts by weight based on 100 parts by weight of the solvent (water). The dispersant was added prior to the input of raw materials for easy mixing and dispersion of the solid material, or a small amount of the dispersant was added depending on the viscosity of the mixed slurry and the degree of agitation in the sequential loading of the raw materials. The antifoaming agent was added in small amounts depending on the degree of bubbles generated after the dispersant or stirring the slurry.
