Description

피셔-트롭쉬 합성반응을 이용한 탄화수소 화합물의 제조 시스템{system for preparing of hydrocarbons by Fischer-Tropsch synthesis}BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for preparing hydrocarbon compounds using Fischer-Tropsch synthesis reaction,

본 발명은 탄화수소 제조 시스템에 관한 것으로, 더욱 상세하게는 피셔-트롭쉬 합성반응을 이용한 탄화수소 제조 시스템에 관한 것이다.The present invention relates to a hydrocarbon manufacturing system, and more particularly, to a hydrocarbon manufacturing system using a Fischer-Tropsch synthesis reaction.

산업화 이후로 석유에 대한 수요는 꾸준히 증가하고 있는 반면, 석유의 매장량은 제한되어 있기 때문에, 석유의 공급이 수요를 따라가지 못하는 시점(피크오일, peak oil)이 필연적으로 도래하게 되며, 많은 학자들이 이러한 피크오일이 이미 도래했거나 조만간 도래할 것으로 예측하고 있다. 따라서 피크오일이 도래한 이후 발생할 경제/사회적 위기 및 충격을 최소화하기 위해, 원유 의존도를 줄이는 기술의 개발과 더불어 원유의 부족한 부분을 원유 이외의 원료에서 제조하여 보충하기 위한 합성석유 제조기술의 개발에 대한 관심이 커지고 있다.Since industrialization, demand for petroleum has steadily increased. However, since oil reserves are limited, it is inevitable that the supply of oil will not meet demand (peak oil, peak oil), and many scholars It is predicted that such a peak oil has already arrived or will soon arrive. Therefore, in order to minimize the economic and social crisis and impact that will occur after the arrival of peak oil, the development of synthetic oil production technology to manufacture and replenish scarce parts of crude oil other than crude oil Interest is growing.

대표적인 합성석유 제조기술 중의 하나인 석탄간접액화(indirect coal liquefaction)는 석탄가스화 및 정제를 통해 얻어진 합성가스(H2+CO)를 피셔-트롭쉬 합성반응을 통해 액상합성석유로 전환하는 공정으로, 석탄의 청정활용이라는 측면과 고부가가치산물을 얻을 수 있다는 측면에서 매우 유망한 기술이다. 특히 석탄은 매장량이 풍부하고, 전세계적으로 고루 분포해 있을 뿐만 아니라, 가격이 싸다는 장점을 지니고 있다.The indirect coal liquefaction process, which is one of the representative synthetic petroleum production technologies, is a process of converting synthesis gas (H 2 + CO) obtained through coal gasification and purification into liquid synthetic oil through Fischer-Tropsch synthesis reaction. It is a very promising technology in terms of clean utilization of coal and high value-added products. In particular, coal is rich in reserves, is distributed throughout the world, and has the advantage of being cheap.

피셔-트롭쉬 합성반응은 1923년 독일의 화학자 피셔(Fischer)와 트롭쉬(Tropsch)가 석탄의 가스화에 의해 합성가스로부터 합성연료를 제조하는 기술을 개발한데서 처음 시작되었다. 피셔-트롭쉬 합성반응은 촉매를 사용하여 합성가스를 탄화수소로 전환하는 반응인데, 여기서 사용되는 촉매는 활성도가 높은 촉매일수록 일반적인 생산성의 지표인 탄소 수가 5 이상인 탄화수소의 생산성을 높이고, 전체적인 탄소 효율을 높일 수 있다.The Fischer-Tropsch synthesis reaction began in 1923 when German chemists Fischer and Tropsch developed a technique for producing synthetic fuels from syngas by coal gasification. The Fischer-Tropsch synthesis reaction is a reaction in which a syngas is converted to a hydrocarbon by using a catalyst. The catalyst used herein is a catalyst having high activity, which increases productivity of hydrocarbons having a carbon number of 5 or more, which is an index of general productivity, .

피셔-트롭쉬 합성반응에 활성을 보이는 물질로는 철(Fe), 코발트(Co), 니켈(Ni), 루테늄(Ru) 등의 그룹 금속물질이 보고되고 있다. 그 중에서 철(Fe)계 촉매는 낮은 제조단가, 우수한 성능, 수성-가스전환반응(WGS, Water-Gas Shift)에도 활성을 보인다는 점 때문에 석탄간접액화와 연계된 피셔-트롭쉬 합성반응에 특히 장점을 보인다.Group metallic materials such as iron (Fe), cobalt (Co), nickel (Ni) and ruthenium (Ru) have been reported as active substances in the Fischer-Tropsch synthesis reaction. Among them, iron (Fe) -based catalysts are particularly suitable for the Fischer-Tropsch synthesis reaction associated with indirect indirect liquefaction because of their low production cost, excellent performance, and activity in water-gas shift (WGS) It looks good.

피셔-트롭쉬 합성반응용 촉매는 일반적으로 제조된(as-prepared) 상태에서는 피셔-트롭쉬 합성반응에 활성이 없다. 따라서 반응을 수행하기 전에 적절한 조건에서 환원(활성화)처리를 수행하여 촉매를 활성을 띄는 형태로 바꿔 주어야 한다.The Fischer-Tropsch synthesis catalyst is not active in the Fischer-Tropsch synthesis reaction in the as-prepared state. Therefore, a reduction (activation) treatment should be carried out under appropriate conditions before the reaction is carried out to convert the catalyst into an active form.

철계 촉매는 철계 탄화물(iron-carbide)이 주요 활성종으로 알려져 있으며, 환원처리 및 반응 중에 다양한 금속/탄화물/산화물 구조가 복잡하게 형성이 되므로, 단순히 금속상이 활성종으로 쓰이는 Co, Ni, Ru계 촉매와 비교할 경우 그 성능이 환원조건에 크게 의존한다.Since iron-based carbides are known as iron-carbide as a main active species, various metal / carbide / oxide structures are complexly formed during the reduction treatment and reaction. Therefore, Compared with the catalyst, its performance is highly dependent on the reduction conditions.

피셔-트롭쉬 합성반응을 수행하기 위해 피셔-트롭쉬 합성반응에 필요한 철계 촉매와 합성가스를 피셔-트롭쉬 합성 반응기에 넣어 우선적으로, 촉매 환원(활성화)반응이 수행되고 다음으로 피셔-트롭쉬 합성반응이 수행된다.In order to carry out the Fischer-Tropsch synthesis reaction, an iron-based catalyst and a syngas necessary for a Fischer-Tropsch synthesis reaction are put into a Fischer-Tropsch synthesis reactor to preferentially perform a catalytic reduction (activation) reaction, A synthesis reaction is carried out.

이와 같이 단일 피셔-트롭쉬 합성 반응기에서 촉매 환원(활성화)반응과 피셔-트롭쉬 합성반응이 수행되기 때문에 사용자는 촉매를 보충하고자 할 때, 합성반응을 중단하고 피셔-트롭쉬 반응기 내부로 투입해야 하는 문제점이 있다.Since the catalytic reduction (activation) reaction and the Fischer-Tropsch synthesis reaction are performed in a single Fischer-Tropsch synthesis reactor, the user must stop the synthesis reaction and introduce it into the Fischer-Tropsch reactor .

또한, 활성화 되지 않는 촉매를 보충하기 때문에 다시 피셔-트롭쉬 합성반응이 수행되기 위해선 많은 시간이 소요된다. In addition, it takes a long time to perform the Fischer-Tropsch synthesis reaction again because it replenishes the catalyst which is not activated.

따라서 상기와 같은 문제점을 해결하기 위한 본 발명의 목적은 피셔-트롭쉬 합성과정에서 추가로 촉매를 투입하기 용이하고, 활성화된 촉매를 공급하여 피셔-트롭쉬 합성반응이 수행되는 시간을 단축할 수 있는 피셔-트롭쉬 합성반응을 이용한 탄화수소 화합물의 제조 시스템을 제공하기 위한 것이다.Accordingly, it is an object of the present invention to solve the above-mentioned problems and it is an object of the present invention to provide a process for synthesizing a Fischer-Tropsch synthesis catalyst, The present invention provides a system for producing a hydrocarbon compound using a Fischer-Tropsch synthesis reaction.

상기와 같은 목적을 달성하기 위하여, 본 발명은 철계 촉매가 장입되고, 제1 합성가스가 주입되어 상기 철계 촉매가 환원처리되고, 상기 환원처리된 철계 촉매와 주입된 제2 합성가스를 교반하는 교반기를 포함하는 촉매 환원 반응기 및 상기 촉매 환원 반응기와 연결된 관을 통해 온라인(online)으로 이동된 상기 교반된 제2 합성가스 및 환원처리된 철계 촉매를 반응시켜 탄화수소 화합물을 제조하는 피셔-트롭쉬 합성 반응기를 포함하는 것을 특징으로 하는 피셔-트롭쉬 합성반응을 이용한 탄화수소 화합물의 제조 시스템을 제공한다.In order to accomplish the above object, the present invention provides a method for producing iron-based catalyst, comprising the steps of charging an iron-based catalyst, injecting a first syngas to reduce the iron-based catalyst, And a Fischer-Tropsch synthesis reactor for producing a hydrocarbon compound by reacting the agitated second syngas and the reduced iron-based catalyst, which are transferred on-line via a pipe connected to the catalyst reduction reactor, The present invention also provides a system for producing a hydrocarbon compound using a Fischer-Tropsch synthesis reaction.

본 발명에 따른 피셔-트롭쉬 합성 반응을 이용한 탄화수소 화합물의 제조 시스템에 따르면, 별도의 반응기에서 촉매를 환원(활성화)시켜 피셔-트롭쉬 반응기에 투입시키기 때문에 피셔-트롭쉬 합성 반응을 이용한 탄화수소 화합물의 제조과정에서 추가로 촉매를 투입하기 용이하고, 활성화된 촉매를 공급하여 피셔-트롭쉬 합성반응을 이용한 탄화수소 화합물이 제조되는 시간을 단축할 수 있다.According to the system for producing hydrocarbon compounds using the Fischer-Tropsch synthesis reaction according to the present invention, since the catalyst is reduced (activated) in a separate reactor and fed to the Fischer-Tropsch reactor, the hydrocarbon compound It is easy to add a catalyst in the production process of the Fischer-Tropsch synthesis catalyst, and the time for producing the hydrocarbon compound using the Fischer-Tropsch synthesis reaction can be shortened by supplying the activated catalyst.

It should be interpreted as meaning and concept consistent with the technical idea of the present invention. Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely preferred embodiments of the present invention, and are not intended to represent all of the technical ideas of the present invention, so that various equivalents And variations are possible.

이하, 첨부된 도면을 참조하여 본 발명에 따른 피셔-트롭쉬 합성반응을 이용한 탄화수소 화합물의 제조방법을 단계별로 더욱 상세히 설명한다.Hereinafter, a method for producing a hydrocarbon compound using a Fischer-Tropsch synthesis reaction according to the present invention will be described in more detail with reference to the accompanying drawings.

도 1은 본 발명의 제1 실시예에 따른 피셔-트롭쉬 합성반응을 이용한 탄화수소 화합물의 제조 시스템을 나타낸 도면이다.1 is a view showing a system for producing a hydrocarbon compound using a Fischer-Tropsch synthesis reaction according to a first embodiment of the present invention.

도 1을 참조하면, 본 발명의 제1 실시예에 따른 피셔-트롭쉬 합성반응을 이용한 탄화수소 화합물의 제조 시스템(100)은 촉매 환원 반응기(10) 및 피셔-트롭쉬 합성 반응기(20)를 포함한다.1, a system 100 for producing a hydrocarbon compound using a Fischer-Tropsch synthesis reaction according to the first embodiment of the present invention includes a catalyst reduction reactor 10 and a Fischer-Tropsch synthesis reactor 20 do.

촉매 환원 반응기(10)는 철계 촉매가 장입되고, 제1 합성가스가 주입되어 철계 촉매가 환원처리된다.The catalyst reduction reactor 10 is charged with an iron-based catalyst, and the first synthesis gas is injected to reduce the iron-based catalyst.

철계 촉매는 철(Fe), 구리(Cu), 칼륨(K) 및 실리카 산화물(SiO2) 포함할 수 있다. 이 때, 철계 촉매는 Fe : Cu : K : SiO2 = 100 : 1 ~ 10 : 1 ~ 20 : 10 ~ 50의 중량비를 가질 수 있다. 구리는 철 100 중량에 대하여 1 ~ 10 중량비 범위로 함유하여 조촉매성분으로 사용할 수 있다. 구리 금속의 함유량이 1 중량비 미만이면 메탄 생성량이 많아지는 문제가 발생하고, 10 중량비를 초과하는 경우에는 반응 활성이 떨어지는 문제가 발생하므로 이 범위를 유지하는 것이 바람직하다. 칼륨 금속은 메탄 생성을 억제시키는 역할을 하며, 질산칼륨, 탄산칼륨 등의 칼륨 함유 화합물을 전구체로 사용 할 수 있다. 칼륨의 함유량이 철 100 중량부에 대하여 1 중량부 미만이면 메탄 생성의 억제 효과를 보기 힘들 수 있고, 20 중량부를 초과하면 촉매의 안정성이 떨어질 수 있으므로 이 범위 내로 함유하고 있는 것이 바람직하다. 실리카 산화물은 지지체 또는 촉매 분산체로 사용하는데 철 100 중량부에 대하여, 10 ~ 50 중량부를 사용하는 것이 바람직하다. 이 때, 실리카 산화물의 사용량이 10 중량부 미만이면 그 사용량이 너무 적어서, 지지체로서의 역할을 수행할 수 없는 문제가 있고, 50 중량부를 초과하면 그 사용 증대에 의한 효과 증대가 없으므로 비경제적이므로 이 범위 내로 사용하는 것이 바람직하다.The iron-based catalyst may include iron (Fe), copper (Cu), potassium (K), and silica oxide (SiO 2 ). At this time, the iron-based catalyst may have a weight ratio of Fe: Cu: K: SiO 2 = 100: 1 to 10: 1 to 20:10 to 50. Copper is contained in a range of 1 to 10 weight ratio with respect to 100 parts by weight of iron and can be used as a co-catalyst component. When the content of the copper metal is less than 1 part by weight, the amount of methane produced increases. When the amount of the copper metal exceeds 10 parts by weight, the reaction activity decreases. The potassium metal serves to inhibit the formation of methane, and potassium-containing compounds such as potassium nitrate and potassium carbonate can be used as precursors. If the content of potassium is less than 1 part by weight based on 100 parts by weight of iron, it may be difficult to obtain an effect of suppressing the formation of methane. If the content of potassium exceeds 20 parts by weight, stability of the catalyst may deteriorate. The silica oxide is used as a support or a catalyst dispersion, and it is preferable to use 10 to 50 parts by weight with respect to 100 parts by weight of iron. If the amount of the silica oxide is less than 10 parts by weight, the amount of the silica oxide used is too small to serve as a support. On the other hand, if the amount of the silica oxide is more than 50 parts by weight, It is preferable to use it as the inside.

또한, 철계 촉매는 철계 촉매는 철(Fe), 구리(Cu), 칼륨(K) 및 실리카 산화물(SiO2) 포함하고 있으며, 나트륨(Na)을 더 포함할 수 있다. 이 때, 철계 촉매는 Fe : Cu : K : SiO2 : Na = 100 : 1 ~ 10 : 1 ~ 20 : 10 ~ 50 : 1 ~ 20의 중량비를 갖는 것이 바람직하다. 나트륨 금속은 메탄 생성을 억제시키는 역할을 한다. 나트륨의 함유량이 철 100 중량부에 대하여 1 중량부 미만이면 메탄 생성의 억제 효과를 보기 힘들 수 있고, 20 중량부를 초과하면, 촉매의 안정성이 떨어질 수 있으므로 범위 내로 함유하고 있는 것이 바람직하다.The iron-based catalyst includes iron (Fe), copper (Cu), potassium (K), and silica oxide (SiO 2 ), and may further include sodium (Na). At this time, the iron-based catalyst preferably has a weight ratio of Fe: Cu: K: SiO 2 : Na = 100: 1 to 10: 1 to 20:10 to 50: 1 to 20. Sodium metal plays a role in suppressing methane production. If the content of sodium is less than 1 part by weight based on 100 parts by weight of iron, it may be difficult to obtain an effect of suppressing the formation of methane. If the content of sodium exceeds 20 parts by weight, the stability of the catalyst may deteriorate.

제1 합성가스는 촉매 환원 반응기에 장입된 철계 촉매를 환원(활성화)시키는 물질로 천연 가스 또는 유사한 경질(light) 탄화수소 공급원료로 부터 생성 될 수 있는 가스(수소와 탄소산화물들의 혼합)을 사용한다. 즉, 제1 합성가스는 H2 또는 CO를 포함할 수 있다.The first synthesis gas uses a gas (a mixture of hydrogen and carbon oxides) that can be generated from a natural gas or a similar light hydrocarbon feedstock as a substance that reduces (activates) an iron-based catalyst charged in a catalytic reduction reactor . That is, the first synthesis gas may comprise H 2 or CO.

촉매 환원 반응기(10)는 교반기(15)를 포함하는데 교반기(15)는 촉매 환원 반응기(10)에서 환원 처리된 철계 촉매와 주입된 제2 합성가스를 교반한다.The catalytic reduction reactor 10 includes a stirrer 15 in which the iron-based catalyst reduced in the catalytic reduction reactor 10 is stirred with the injected second synthesis gas.

제2 합성가스는 촉매 환원 반응기에 장입된 철계 촉매를 환원(활성화)시키는 물질로 천연 가스 또는 유사한 경질(light) 탄화수소 공급원료로 부터 생성 될 수 있는 가스(수소와 탄소산화물들의 혼합)를 사용한다. 즉, 제1 합성가스는 H2 또는 CO를 포함할 수 있다. 또한, 제2 합성가스는 N2, CO2 및 CH4 중 적어도 하나를 더 포함할 수 있다.The second syngas uses a gas (a mixture of hydrogen and carbon oxides) that can be generated from a natural gas or a similar light hydrocarbon feedstock as a material that reduces (activates) the iron-based catalyst charged into the catalytic reduction reactor .
