Description

석탄액화유를 이용한 대체연료{an alternative fuel using of coal liquefaction oil}An alternative fuel using of coal liquefaction oil

본 발명은 유연탄에서 추출된 혼합석탄 추출물(Mixed Coal Extract, 이하 "MCE"라 함) 50~80 중량%, 석탄을 가스화한 후 촉매를 통해 생성되는 에탄올 및 메탄올 10~20 중량%, 석탄에서 추출된 노말 부탄올 5~15 중량%, 석탄에서 추출된 톨루엔 5~10 중량%를 포함하는 것을 그 특징으로 하여, 휘발유 자동차 대체연료로서 사용하는 것이다.The present invention is a mixed coal extract extracted from bituminous coal (Mixed Coal Extract, hereinafter referred to as "MCE") 50 to 80% by weight, ethanol and methanol produced by the catalyst after gasification of coal 10 to 20% by weight, extracted from coal It is characterized in that it comprises 5 to 15% by weight of normal butanol, 5 to 10% by weight of toluene extracted from coal, it is used as a gasoline automobile alternative fuel.

국내에서는 석유 등 에너지 수급에 있어 그 한계를 드러내면서, 87년 "대체에너지개발촉진법"을 제정,공포하여 국내 실정을 고려한 대체에너지를 정의하고, 대체에너지기술개발을 계속적으로 이행해 오고 있으나, 특히, 자동차연료에 관하여서 아직까지는 휘발유를 대체할 수 있는 상업용 연료가 제시되지 못하고 있는 실정이다.In Korea, the limit of energy supply and demand was revealed, and the Alternative Energy Development Promotion Act was enacted and promulgated in 1987 to define alternative energy in consideration of the domestic situation and to continuously develop alternative energy technologies. As for fuel consumption, commercial fuels that can replace gasoline have not yet been proposed.

한편, 분포지역과 매장량이 한정되어 있는 석유에 비하여 석탄은 가채년수가 길고 세계 전역에 널리 분포되어 있으므로 가격이 저렴하며 향후 에너지 공급의 안정을 기할 수 있다는 장점이 있으나 사용시 석유에 비하여 저장, 수송, 연소상의불편성과 환경공해 문제가 따르고 수송시 방대한 설비가 필요한 단점을 가지고 있었다. 이에, 지난 80년대부터 석탄 액화 기술로서 석탄·물 혼합연료(Coal-Water Mixture)의 기술개발을 위한 연구가 대두되어 왔으며, 이는 미분탄(유연탄)에 30%정도의 물과 약간의 첨가제를 혼합하여 유체화하였기 때문에 수송성은 액체연료와 같고 연소성은 석탄의 성상을 갖고 있어 별도의 하역설비와 벨트콘베어 등의 수송설비 그리고 분쇄기 등의 연소 전처리 설비가 필요 없을 뿐만 아니라 파이프 수송 및 탱크저장이 가능하므로 분진의 비산도 없어 환경면에서도 유리한 기술이라는 장점을 제시하였다.On the other hand, compared to petroleum, which has a limited distribution area and reserves, coal has a long number of years of residing and is widely distributed throughout the world, so it is inexpensive and can stabilize energy supply in the future. It has disadvantages of combustion inconsistency and environmental pollution, and requires extensive equipment for transportation. Therefore, research into the technology development of coal-water mixture fuel has emerged as a coal liquefaction technology since the 80's, which is a mixture of pulverized coal (petroleum coal) with about 30% of water and some additives. Because of fluidization, transport is the same as liquid fuel, and combustibility has the properties of coal.There is no need for separate unloading equipment, transportation equipment such as belt conveyor, and pre-combustion treatment equipment such as pulverizer. There is no scattering of water, which is an advantage in terms of environment.

일반적으로 석탄으로부터 에너지 변환 방법은 석탄의 열분해(Pyrolysis), 석탄의 가스화 (Gasification)로 부터의 가스합성, 석탄의 액화(Liquifaction), Coal Water Mixture(CWM), Coal Oil Mixture(COM) 등을 들 수 있으며, 건류 타르(Tar)와 건류가스는 에너지 변환 중 생성되는 부산물로서 이용된다. 특히 석탄액화반응은 석탄을 가스화로 만들고 그 가스상에 수소(H2)를 첨가하든가, 또는 석탄으로부터 추출된 액체에 수소를 첨가하여 합성유류를 만드는 방법으로서 직접액화와 간접액화법이 있으며 직접액화의 경우는 석탄을 고온, 고압 하에서 촉매와 수소의 존재하에서 반응시킴으로 고품질의 유류제품을 생산하는 기술이고, 간접액화공정은 석탄을 가스화한 후 촉매에 의한 액화유를 생성하는 공정으로서 에탄올(Ethanol)을 비롯하여 메탄올(Methanol) 등의 액화유를 제조할 수 있는 기술이다.Generally, coal to energy conversion methods include pyrolysis of coal, gas synthesis from coal gasification, liquefaction of coal, coal water mixture (CWM), and coal oil mixture (COM). Dry tar and dry gas are used as by-products generated during energy conversion. In particular, coal liquefaction is a method of making coal into gas and adding hydrogen (H2) to the gas, or adding hydrogen to a liquid extracted from coal to make synthetic oil. There are direct and indirect liquefaction methods. Is a technology to produce high quality oil products by reacting coal in the presence of catalyst and hydrogen under high temperature and high pressure. Indirect liquefaction process is a process to produce liquefied oil by catalyst after gasification of coal, including ethanol, It is a technology that can produce liquefied oil such as methanol.

그러나 이러한 액화기술을 통해 제조된 석탄 추출물의 경우 생산단가가 높아 대량 생산하는 것이 어려우며, 기존 기술은 중유로서 난방유 또는 제철용 연료유등으로 사용되어 오는데 국한되어 왔다.However, in the case of coal extract produced through such a liquefaction technology, it is difficult to produce a large amount due to high production cost, and the existing technology has been limited to being used as heating oil or fuel oil for steelmaking as heavy oil.

더욱이, 석탄을 액화한 연료를 자동차연료로 사용하는 것은 기존 기술로는 한계점을 가지며, 또한 석탄 추출물의 경우 기존의 석탄에 비해 발열량이 증가하는 등의 장점이 있으나 자동차 연료로 사용했을 경우 환경오염 등의 문제 및 자동차 성능상의 문제를 야기시킬 수 있다는 문제점도 있었다.In addition, the use of coal liquefied fuel as an automobile fuel has a limitation in the existing technology, and in the case of coal extract, there is an advantage that the calorific value increases compared to the existing coal, but when used as an automobile fuel, environmental pollution, etc. There is also a problem that can cause problems in the car performance and car performance.

따라서, 본 발명은 종래의 석탄 액화기술의 경우 일반적으로 제철용 연료유 등 중유의 품질을 가지고 있으나 이를 자동차 연료로 적합하게 제조하기 위해서는 석탄 액화추출물을 원료로 하되 석탄에서 추출되는 각 액화유 또는 가스체를 본 발명의 조성비율에 맞춰 기존 휘발유 품질기준에 맞추도록 하였으며 환경오염의 주 원이니 되고 있는 함함량 및 벤젠을 거의 제외시켰으며 무엇보다도 출력을 높이기 위해 옥탄가를 휘발유 품질이상으로 높이고, 별도의 자동차 엔진의 개조없이 사용가능하기 때문에 자동차용 연료로써의 알콜연료의 저변확대를 달성할 수 있으며, 석유 일변도의 에너지원을 매장량이 약 10조 Ton이상 되며 전세계적으로 고르게 분포되어 있는 석탄을 이용한 에너지의 개발로 에너지원의 다변화와 불안정한 석유에너지의 대체원으로 활용할 수 있는 것을 그 목적으로 한다.Therefore, the present invention generally has the quality of heavy oil, such as steel fuel oil in the case of the conventional coal liquefaction technology, but in order to prepare it as an automobile fuel, coal liquefied extract as a raw material, but each liquefied oil or gas extracted from coal The sieve was made to meet the existing gasoline quality standards in accordance with the composition ratio of the present invention and almost eliminated the contents of benzene and benzene, which are the main sources of environmental pollution. Since it can be used without modification of automobile engines, it is possible to achieve a low base of alcohol fuel as a fuel for automobiles, and the energy source of unilateral oil reserves is about 10 trillion tons and the energy is distributed evenly around the world. To diversify energy sources and replace unstable petroleum energy. And that can be utilized for that purpose.

또한, 본 발명은 기존 제철용으로 사용되고 있는 석탄생성물의 일종인 코크스 등을 활용하고 버려지는 폐기물을 통해서도 이와 같은 석탄액화추출물은 재생될 수 있어 환경오염 뿐 아니라 자원재생의 효과를 안출하고자 하는 목적을 가지고 있다.In addition, the present invention utilizes coke, which is a kind of coal product used for steel making, and the coal liquefied extract can be regenerated through waste that is discarded. Have.

본 발명은 상기와 같은 기술적 과제를 해결하기 위하여 안출된 것으로서, 유연탄에서 추출된 MCE 50~80 중량%, 석탄을 가스화한 후 촉매를 통해 생성되는 에탄올 및 메탄올 10~20 중량%, 석탄에서 추출된 노말 부탄올 5~15 중량%, 석탄에서 추출된 톨루엔 5~10 중량%를 포함하는 것을 그 특징으로 하며, 여기에 성능 향상을 위해 기타 첨가제를 부가하는 것이 바람직하다.The present invention has been made in order to solve the above technical problems, 50 ~ 80% by weight MCE extracted from bituminous coal, 10 to 20% by weight of ethanol and methanol produced through the catalyst after gasification of coal, extracted from coal It is characterized in that it comprises 5 to 15% by weight of normal butanol, 5 to 10% by weight of toluene extracted from coal, it is preferable to add other additives to improve the performance.

상기 MCE(mixed coal extract)는 본 발명의 기본 구성성분으로서 석탄을 300~500℃ 이상의 고온에서 200∼700기압의 고압수소와 반응시켜 개열, 탈산소, 탈황, 탈질소하여 생성되는 저급탄화수소유로 석탄액화유를 이용한 자동차 연료의 기본 성분이며, 노말부탄올은 저온에서의 시동성을 향상시키기 위한 것이고, 소량 첨가하는 석탄추출 톨루엔은 연료의 폭발력을 향상시키기 위한 것이고, Tar를 액화시킨 에탄올은 옥탄가 향상 및 연소율을 향상시키기 위한 것이다.The MCE (mixed coal extract) is a low-carbon hydrocarbon produced by reacting coal with high-pressure hydrogen of 200 to 700 atm at a high temperature of 300 to 500 ° C. as a basic constituent of the present invention. It is a basic component of automobile fuel using liquefied oil, normal butanol is for improving startability at low temperature, and the addition of a small amount of coal extract toluene is for improving the explosive power of fuel. Is to improve.

또한, 본 발명에 따른 알코올 연료조성물에는 필요에 따라서 기타첨가제를 첨가시키는 것을 포함할 수 있는데 이는 본 발명 연료의 연소시 옥탄가 향상 및 배출가스를 저감시키기 위한 것이다.In addition, the alcohol fuel composition according to the present invention may include adding other additives as necessary, which is to improve the octane number and reduce the exhaust gas during combustion of the fuel of the present invention.

이러한 조성을 갖는 본 발명의 석탄액화유를 이용한 자동차 연료 조성물은 가솔린에 비해 방향족 화합물의 함량이 거의 60-80%이하이며 인체에 해로운 벤젠은 전혀 검출되지 않으며, 환경오염의 주범이 되고 있는 황함량이 거의 검출되지 않는다. 또한 기존의 석탄액화유 보다 높은 발열량을 갖고 있어 그 자체로서는 자동차 연료로서 부적당한 기존의 MCE(mixed coal extract)에 상기한 각각의 석탄 추출물들을 일정 비율로 혼합시킴으로써 가솔린과 거의 같거나 보다 우수한 성능을 발휘할 수 있다.The automobile fuel composition using the coal liquefied oil of the present invention having such a composition has an aromatic compound content of about 60-80% or less compared to gasoline, and no harmful benzene is detected at all, and sulfur content, which is the main cause of environmental pollution, is detected. Rarely detected. In addition, it has a higher calorific value than conventional coal liquefied oils, so that each coal extract described above is mixed at a predetermined ratio with the existing MCE (mixed coal extract), which is not suitable as an automobile fuel. Can be exercised.

석탄액화유를 이용한 자동차 연료를 가솔린차량의 연료로 사용하기 위해서는 옥탄가 및 증기압을 휘발유 품질 수준으로 높이는 것이 기본 과제인데, 본 발명에서는 이를 위하여 Tar를 액화시킨 에탄올를 통해 옥탄가를 98-100까지 증가시켰으며 탄화수소 등급 C5-C6에 해당하는 톨루엔을 특정비율로 혼합 사용함으로써 혼합연료의 증기압 역시 휘발유 품질 기준인 44-96 kpa 수준으로 조정할 수 있도록 하였다.In order to use automobile fuel using coal liquefied oil as a fuel of a gasoline vehicle, it is a basic task to increase octane number and vapor pressure to gasoline quality level. By using a specific ratio of toluene, corresponding to hydrocarbon grade C5-C6, the vapor pressure of the mixed fuel can also be adjusted to the gasoline quality standard 44-96 kpa.

또한 석탄액화유의 경우 올레핀 함량이 높아 산화활동이 Gum을 다량 검출하게 만드는데 이는 저장 및 수송 상의 문제를 야기할 수 있으므로 본 발명의 연료는 이를 발생시키는 근본 원인인 올레핀 함량을 휘발유 품질 수준인 20%이하로 감소시켰으며, 세계적으로 문제가 되고 있는 황을 1ppm미만의 수준으로 대폭 낮췄으며 유독물질인 벤젠의 경우는 휘발유와 달리 완전히 제거했다.In addition, in the case of coal liquefied oil, the olefin content is high, so that the oxidation activity detects a large amount of Gum, which may cause storage and transportation problems, and thus the fuel of the present invention is less than 20% of the gasoline quality level. It lowered the sulfur level, which is a problem worldwide, to less than 1 ppm, and completely removed benzene, which is a toxic substance, unlike gasoline.

그리고 본 발명은 석탄 액화유의 경우 Nitrogen이 다량 함유되어 NOx의 발생을 야기시킬 수 있는데 이를 위해 Nitrogen의 함량을 대폭 줄였으며, 겨울철 시동성을 위해 석탄 액화추출물 중 노말 부탄올을 첨가하여 저온시동성을 개선할 뿐만 아니라 부탄올로 인하여 응고점을 가솔린보다 낮출 수 있어 추운 지방에서도 사용할 수 있도록 하였다.In the present invention, in the case of coal liquefied oil, Nitrogen is contained in a large amount, which may cause NOx generation. To this end, the content of Nitrogen is greatly reduced. But because of the butanol can lower the freezing point than gasoline can be used in cold climates.

이하, 본 발명에 따른 알코올 연료 조성물은 다음 실시예를 통하여 보다 명확하게 이해될 수 있다.Hereinafter, the alcohol fuel composition according to the present invention can be more clearly understood through the following examples.
