Description
본 발명은 겨울철 건물을 건축할 때 건물의 슬라브 및 벽체가 어는 것을 방지하기 위해 불을 피우는 용도로 많이 사용되는 고화 에틸알코올 연료 조성물 및 이를 이용한 고체연료 제조방법에 관한 것으로서, 보다 상세하게는 유해한 메탄올 타입이 아닌 유해성이 없는 식물성 에탄올을 이용한 고체 타입으로 구성하여 유해가스 발생이 없고, 연소 후 잔여물이 생기지도 않으면서 고체이기 때문에 넘어져도 안전하고, 착화 및 소화가 용이하고 간편하며, 이동 편의성도 갖추면서 발열양도 메탄올 보다 증대시켜 열효율도 높이도록 개선된 고화 에틸알코올 연료 조성물 및 이를 이용한 고체연료 제조방법에 관한 것이다.The present invention relates to a solidified ethyl alcohol fuel composition, which is widely used for making fires to prevent slabs and walls of buildings from freezing when constructing buildings in winter, and to a method for producing solid fuel using the same. It is composed of a solid type using non-hazardous vegetable ethanol, so it does not generate harmful gases and does not produce residues after combustion, so it is safe even if it falls because it is solid, and is easy and convenient to ignite and extinguish, and is also convenient to move. The present invention relates to a solidified ethyl alcohol fuel composition improved to increase thermal efficiency by increasing the amount of heat generated compared to methanol, and a method for producing solid fuel using the same.
화력의 에너지원으로 이용되는 연료는 크게 나우어 목탄, 코오코스, 석탄과 같은 고체 연료와 알코올, 벤졸, 가솔린과 같은 액체연료와 LPG와 같은 기체연료로 구분된다.Fuels used as energy sources for thermal power are broadly divided into solid fuels such as charcoal, cocos, and coal, liquid fuels such as alcohol, benzol, and gasoline, and gaseous fuels such as LPG.
그러나, 고체연료나 액체연료 및 기체연료들은 매장량이 제한되어 있거나 제조비용이 높기 때문에 새로운 값싸고 매장량이 풍부한 에너지원을 개발하기 위하여 많은 연구가 진행되고 있다.However, because solid fuels, liquid fuels, and gaseous fuels have limited reserves or high manufacturing costs, much research is being conducted to develop new cheap and resource-rich energy sources.
이러한 화력 에너지원인 연료는 겨울철 건물을 건축할 때 건물의 슬라브 및 벽체가 어는 것을 방지하기 위해 불을 피우는 용도로 많이 활용된다.Fuel, which is a source of thermal energy, is often used to make fires when constructing buildings in winter to prevent the slabs and walls of the building from freezing.
현재 대표적으로 사용되는 화력 에너지원인 연료는 알코올 연료로서 액상의 메탄올이 주로 사용된다. 이때, 메탄올이 주로 사용되는 이유는 상온과 일반적인 대기압에서도 저장과 이송이 쉽고, 연료 공급(벙커링)도 항만의 기존 연료 설비를 간단히 개조하여 활용할 수 있어서 초기 인프라를 구축하는 비용이 상대적으로 적기 때문이다.Currently, the fuel that is the most commonly used thermal energy source is alcohol fuel, and liquid methanol is mainly used. At this time, methanol is mainly used because it is easy to store and transport even at room temperature and normal atmospheric pressure, and fuel supply (bunkering) can be used by simply modifying the existing fuel facilities at the port, so the cost of building the initial infrastructure is relatively low. .
그런데, 액상 메탄올 연료는 유독가스 발생, 저장 도중 안정성 결여, 짧은 지속시간 및 연소시 액화로 인한 취급 부주의에 따른 화재의 위험성 등 여러 가지 문제점이 있어 이를 개선한 예가 이를 겔 또는 졸 형태로 만든 것이다.However, liquid methanol fuel has several problems, such as the generation of toxic gas, lack of stability during storage, short duration, and the risk of fire due to careless handling due to liquefaction during combustion. An example of improving this is making it into a gel or sol form.
하지만, 상기 겔 또는 졸 형태의 알코올 연료가 저장 안정성을 증대시키기는 하였지만, 메탄올인 관계로 열량이 매우 낮아 비효율적이며, 이를 해결하기 위해 탄소수가 2개 이상인 알코올을 첨가하고 있으나 이 경우에는 겔 또는 졸이 잘 형성되지 못하는 단점이 파생되었다.However, although the alcohol fuel in the form of a gel or sol increases storage stability, it is inefficient due to its very low calorific value because it is methanol. To solve this problem, alcohol with more than 2 carbon atoms is added, but in this case, the gel or sol fuel is inefficient. The disadvantage of not being able to form well is derived from this.
특히, 겔 또는 졸을 형성했다고 하더라도 상온에서 파괴되기 때문에 실효성이 없었다.In particular, even if a gel or sol was formed, it was ineffective because it was destroyed at room temperature.
이에, 최근에는 메탄올과 유지 및 가성소다를 혼합하여 고체상태로 만든 것이 출시되고 있다.Accordingly, recently, products made by mixing methanol, fat, and caustic soda into a solid state have been released.
그러나, 원료가 메탄올인 관계로 일산화탄소, 포름알데히드 등 유해가스 방출로 인해 이에 대한 규제가 커지고 있고, 무엇보다도 연소 후 다량의 잔유물이 발생하는 등의 문제로 인해 그에 대한 대안이 필요한 실정이다.However, since the raw material is methanol, regulations on it are increasing due to the emission of harmful gases such as carbon monoxide and formaldehyde, and above all, due to problems such as the generation of a large amount of residue after combustion, an alternative is needed.
따라서, 본 발명은 상술한 바와 같은 종래 기술상의 제반 문제점들을 감안하여 이를 해결하고자 창출된 것으로, 유해한 메탄올 타입이 아닌 유해성이 없는 식물성 에탄올을 이용한 고체 타입으로 구성하여 유해가스 발생이 없고, 연소 후 잔여물이 생기지도 않으면서 고체이기 때문에 넘어져도 안전하고, 착화 및 소화가 용이하고 간편하며, 이동 편의성도 갖추면서 발열양도 메탄올 보다 증대시켜 열효율도 높이도록 개선된 고화 에틸알코올 연료 조성물 및 이를 이용한 고체연료 제조방법을 제공함에 그 주된 목적이 있다.Therefore, the present invention was created to solve the problems in the prior art in consideration of the problems in the prior art as described above. It is composed of a solid type using harmless vegetable ethanol rather than a harmful methanol type, so there is no generation of harmful gases and no residual after combustion.

However, this is not intended to limit the embodiments according to the concept of the present invention to a specific disclosed form, and should be understood to include all changes, equivalents, and substitutes included in the spirit and technical scope of the present invention.
본 발명에 따른 고화 에틸알코올 연료 조성물은 이소프로필알콜(Isopropyl Alcohol) 1-5중량%, 스테아린산(Stearic Acid) 0.5-2.0중량%, 메틸에틸케톡심(Methyl ethyl ketoxime) 2.0-7.0중량%, 연수(軟水) 2.0-5.0중량%, 수산화나트륨(Sodium hydroxide) 0.5-1.0중량% 및, 나머지 식물성 에탄올(Ethanol)로 이루어진다.The solidified ethyl alcohol fuel composition according to the present invention includes 1-5% by weight of isopropyl alcohol, 0.5-2.0% by weight of stearic acid, 2.0-7.0% by weight of methyl ethyl ketoxime, and soft water. It consists of 2.0-5.0% by weight of water, 0.5-1.0% by weight of sodium hydroxide, and the remainder is vegetable ethanol.
이때, 이소프로필알콜(Isopropyl Alcohol)은 수산기에 연결된 이소프로필기로서 알코올 탄소 원자가 두 개의 다른 탄소 원자에 부착되는 2차 알코올의 가장 간단한 구조를 갖는다.At this time, Isopropyl Alcohol is an isopropyl group connected to a hydroxyl group and has the simplest structure of a secondary alcohol in which the alcohol carbon atom is attached to two other carbon atoms.
이러한 이소프로필알콜은 CAS No: 67-63-0에 해당하는 물질로서 발열량을 높이기 위해 첨가되며, 발열량은 메탄올 ＜ 에탄올 ＜ 이소프로필알콜 순서로 높다.This isopropyl alcohol is a substance corresponding to CAS No: 67-63-0 and is added to increase the calorific value, and the calorific value is higher in the order of methanol < ethanol < isopropyl alcohol.
그리고, 스테아린산(Stearic Acid)은 CAS No: 57-11-4에 해당하는 포화지방산으로서, 수산화나트륨과 중화반응하여 물과 염을 생성하기 위해 첨가된다.Additionally, stearic acid is a saturated fatty acid corresponding to CAS No: 57-11-4, and is added to neutralize sodium hydroxide to produce water and salt.
또한, 메틸에틸케톡심(Methyl ethyl ketoxime)은 CAS No:96-29-7에 해당하는 물질로서, 내수성과 내열성이 뛰어나고 특히 피막형성에 따른 고상화 지연을 방지하기 위해 첨가된다.In addition, methyl ethyl ketoxime is a material corresponding to CAS No: 96-29-7 and has excellent water resistance and heat resistance, and is especially added to prevent delay in solidification due to film formation.
뿐만 아니라, 연수(軟水)는 화학 용어로 단물과 동의어로서, 칼슘이나 마그네슘 등 광물질을 함유하지 않거나 아주 조금 함유하고 있는 물을 말하며, 염 발생을 억제하여 고상화 지연을 차단하기 위해 일반 물이 아닌 연수를 사용한다.In addition, soft water is a chemical term synonymous with sweet water, and refers to water that does not contain or contains only a small amount of minerals such as calcium or magnesium, and is not ordinary water to suppress the generation of salts and prevent a delay in solidification. Use soft water.
무엇보다도, 스테아린산에 의해 유도된 산성화, 즉 산성 물질과 염기성의 수산화나트륨의 반응에 의해 염이 생성되면서 고상화된다.Above all, acidification induced by stearic acid, that is, the reaction of an acidic substance with basic sodium hydroxide, produces a salt and solidifies it.
즉, 수산화나트륨(Sodium hydroxide)은 백색 고체 이온 화합물로서, 연수와 반응하여 수용액을 형성하며, 특히 스테아린산과 반응하여 염을 발생시키면서 고상화된다.That is, sodium hydroxide is a white solid ionic compound that reacts with soft water to form an aqueous solution and, in particular, solidifies by reacting with stearic acid to generate salt.
예컨대, C18H36O2 + NaOH → Na(C18H35O2) + H2O와 같다.For example, C 18 H 36 O 2 + NaOH → Na(C 18 H 35 O 2 ) + H 2 O.
특히, 수산화나트륨은 상온, 더 바람직하게는 10-18℃ 부근에서 염으로 고상화가 잘 이루어지는 특성이 있다.In particular, sodium hydroxide has the property of being easily solidified into salt at room temperature, more preferably around 10-18°C.
그리고, 식물성 에탄올은 인체무해성과 친환경성을 가지면서 메탄올 보다 높은 발열량을 가져 더 효율적인 연료를 구현할 수 있다.In addition, vegetable ethanol is harmless to the human body and eco-friendly, and has a higher calorific value than methanol, making it a more efficient fuel.
본 발명에 따른 고화 에틸알코올 연료 조성물에 의한 발열 효과를 확인하기 위해, 이소프로필알콜 5중량%, 스테아린산 1.5중량%, 메틸에틸케톡심 5중량%, 연수 2중량%, 수산화나트륨 0.5중량% 및 식물성 에탄올 86중량%로 조성된 고체 연료 시료를 만들었다.In order to confirm the heating effect by the solidified ethyl alcohol fuel composition according to the present invention, 5% by weight of isopropyl alcohol, 1.5% by weight of stearic acid, 5% by weight of methyl ethyl ketoxime, 2% by weight of soft water, 0.5% by weight of sodium hydroxide, and vegetable A solid fuel sample composed of 86% by weight ethanol was prepared.
이렇게 만들어진 시료 콘트리트 양생에 적용한 결과, 평균 400℃의 온도가 유지되는 발열량으로 양생작업에 효과적으로 기여함을 확인하였다.As a result of applying the curing of the sample concrete made in this way, it was confirmed that it effectively contributes to the curing work with the calorific value maintained at an average temperature of 400℃.
또한, 종래 메탄올 겔(젤리) 타입과 비교하여 연소시간과 총 발열량을 비교하였고 그 결과는 아래 표 1에 나타내었다.In addition, the combustion time and total calorific value were compared with the conventional methanol gel (jelly) type, and the results are shown in Table 1 below.

뿐만 아니라, 일산화탄소, 포름알데히드를 포함한 유해가스 발생 여부를 확인한 결과, 모두 허용치 이하로 확인되었다.In addition, as a result of checking whether harmful gases including carbon monoxide and formaldehyde were generated, all were confirmed to be below the allowable level.
특히, 에탄올은 완전연소되면서 아래 반응식과 같이 이산화탄소와 물만 생성하기 때문에 찌꺼기가 발생하지 않는 장점도 있다.In particular, ethanol has the advantage of not generating residue because it only produces carbon dioxide and water as shown in the reaction equation below when completely burned.
C2H5OH(ℓ) + 3O2(g) → 2CO2(g) + 3H2O(ℓ)C 2 H 5 OH(ℓ) + 3O 2 (g) → 2CO 2 (g) + 3H 2 O(ℓ)
이에 따라, 본 발명에 따른 조성물은 목적하는 바를 달성하고 있는 것으로 최종 확인되었다.Accordingly, it was finally confirmed that the composition according to the present invention achieved its intended purpose.
이에 더하여, 본 발명에서는 상기 연료 조성물 100중량부에 대해, 술폰산나트륨크실렌(Sodium xylene sulfonate) 2.5중량부, 디메틸폴리실록산(Dimethylpolysiloxane) 5.5중량부, 프로필렌글리콜(Propylene glycol) 8.5중량부, N,N-디메틸아미노프로필아크릴아미드(N,N-Dimethylaminopropylacrylamide) 5.5중량부를 더 첨가할 수 있다.In addition, in the present invention, based on 100 parts by weight of the fuel composition, 2.5 parts by weight of sodium xylene sulfonate, 5.5 parts by weight of dimethylpolysiloxane, 8.5 parts by weight of propylene glycol, N, N- An additional 5.5 parts by weight of dimethylaminopropylacrylamide (N,N-Dimethylaminopropylacrylamide) can be added.
여기에서, 술폰산나트륨크실렌(Sodium xylene sulfonate)은 CAS No: 1300-72-7에 해당하는 물질로서, 착색을 억제하고, 피막을 박리 제거하여 고상화를 촉진하는데 기여하도록 첨가된다.Here, sodium xylene sulfonate is a substance corresponding to CAS No: 1300-72-7, and is added to suppress coloring, remove peeling off the film, and contribute to promoting solidification.
또한, 디메틸폴리실록산(Dimethylpolysiloxane)은 CAS No: 9016-00-6에 해당하는 물질로서, 짧은 사슬의 폴리실록산이 낮은 표면장력을 유지시켜 디웨이팅(Dewetting) 효과를 유도함으로써 기포를 억제하여 표면 품질을 향상시키기 위해 첨가된다.In addition, dimethylpolysiloxane is a material corresponding to CAS No: 9016-00-6. Short-chain polysiloxane maintains low surface tension and induces a dewetting effect, suppressing bubbles and improving surface quality. It is added to do so.
뿐만 아니라, 프로필렌글리콜(Propylene glycol)은 CAS No: 57-55-6에 해당하는 물질로서, 무독성과 내부식성, 동결융해저항성을 높이기 위해 첨가된다.In addition, propylene glycol is a substance corresponding to CAS No: 57-55-6 and is added to increase non-toxicity, corrosion resistance, and freeze-thaw resistance.
아울러, N,N-디메틸 아미노 프로필 아크릴 아미드(N,N-Dimethylaminopropylacrylamide)는 CAS No: 3845-76-9에 해당하는 물질로서, 유동성과 흐름성을 증대시키면서 수축방지를 통해 균열을 억제하기 위해 첨가된다.In addition, N,N-Dimethylaminopropylacrylamide is a substance corresponding to CAS No: 3845-76-9, and is added to suppress cracking by preventing shrinkage while increasing fluidity and flowability. do.
상술한 시료에 상기 추가 성분들을 그대로 함유시킨 상태에서 열량과 연소시간을 테스트한 결과, 총열량은 650kcal 더 늘었고, 연소시간은 40분 정도 더 연장되었으며, 고화 저해나 엉김, 표면 부상이나 석출 등이 전혀 발생하지 않았고, 크랙도 생기지 않았다. 또한, 폭발이나 과열도 발생하지 않아 안전성이 확인되었다.As a result of testing the heat quantity and combustion time while containing the above additional ingredients in the above-mentioned sample, the total heat quantity increased by 650 kcal, the combustion time was extended by about 40 minutes, and there was no inhibition of solidification, agglomeration, surface flotation, or precipitation. It didn't happen at all, and there were no cracks. Additionally, safety was confirmed as no explosion or overheating occurred.
덧붙여, 본 발명에 따른 연료 조성물중 에탄올은 에탄올 100중량부에 대해, 옥수수분말 2.5중량부 및 황산 1.5중량부를 혼합한 상태로 사용될 수 있다.In addition, ethanol in the fuel composition according to the present invention can be used in a mixture of 2.5 parts by weight of corn powder and 1.5 parts by weight of sulfuric acid with respect to 100 parts by weight of ethanol.
이때, 옥수수분말은 에탄올의 착화성과 발열성을 증대시키고, 황산은 에탄올과 반응하여 다이에틸 에터(Diethyl ether)를 생성함으로써 인화성을 높여 착화성과 발열성을 증대시키는데 기여한다. 다만, 과량으로 첨가되면 안전성을 저해할 수 있으므로 미량, 바람직하게는 2중량부 미만으로 첨가되어야 한다.At this time, corn powder increases the ignition and heat generation of ethanol, and sulfuric acid reacts with ethanol to produce diethyl ether, contributing to increasing ignition and heat generation by increasing flammability. However, if added in excessive amounts, safety may be impaired, so it should be added in a trace amount, preferably less than 2 parts by weight.
뿐만 아니라, 본 발명에 따른 연료 조성물중 메틸에틸케톡심은 메틸에틸케톡심 100중량부에 대해, 송진 5중량부 및 파라핀오일 3.5중량부를 혼합한 상태로 사용될 수 있다.In addition, methyl ethyl ketoxime in the fuel composition according to the present invention can be used in a mixture of 5 parts by weight of rosin and 3.5 parts by weight of paraffin oil for 100 parts by weight of methyl ethyl ketoxime.
이 경우, 송진과 파라핀오일은 메틸에틸케톡심의 인화 증기 발생과 독성을 억제하고, 연소시 그을음을 없애고 냄새를 줄이는데 기여한다.In this case, rosin and paraffin oil suppress the generation of flammable vapor and toxicity of methyl ethyl ketoxime, and contribute to eliminating soot and reducing odor during combustion.
이와 같은 조성물은 다음과 같은 방법으로 제조된다. 이때, 배합비는 앞서 설명한 바와 같고, 여기에서는 배합하는 순서 위주로 설명하기로 한다.Such a composition is prepared in the following manner. At this time, the mixing ratio is the same as previously described, and the description here will focus on the mixing order.
즉, 본 발명에 따른 고화 에틸알코올 연료, 다시 말해 고체연료 제조방법은 도 1의 예시와 같이, 선공정과 후공정으로 분리된다.That is, the method for producing solidified ethyl alcohol fuel, that is, solid fuel, according to the present invention is divided into a pre-process and a post-process, as shown in the example of FIG. 1.
예컨대, 선공정은 에탄올과 이소프로필알콜과 스테아린산과 메틸에틸케톡심의 혼합과정이고, 후공정은 연수와 수산화나트륨의 용해과정이다.For example, the first process is a mixing process of ethanol, isopropyl alcohol, stearic acid, and methyl ethyl ketoxime, and the post process is a dissolution process of soft water and sodium hydroxide.
보다 구체적으로, 먼저 교반기에 투입된 식물성 에탄올에 이소프로필알콜을 첨가한 후 에탄올 혼합액을 40-45℃까지 승온시키는 제1단계가 수행된다.More specifically, the first step is performed by adding isopropyl alcohol to the vegetable ethanol introduced into the stirrer and then heating the ethanol mixture to 40-45°C.
상기 제1단계에서 에탄올 혼합액을 승온시키는 이유는 포화지방산의 반응을 촉진하여 산성화 유도를 가속화시키기 위함이다.The reason for raising the temperature of the ethanol mixture in the first step is to accelerate the induction of acidification by promoting the reaction of saturated fatty acids.
상기 제1단계 후 에탄올 혼합액을 50-60rpm으로 저속 교반하면서 스테아린산을 먼저 투입하여 녹인 다음, 다 녹으면 메틸에틸케톡심을 첨가한 상태에서 30분간 더 교반하는 제2단계가 수행된다.After the first step, stearic acid is first added and dissolved while stirring the ethanol mixture at a low speed of 50-60 rpm, and when it is completely dissolved, a second step is performed in which methyl ethyl ketoxime is added and stirred for an additional 30 minutes.
상기 제2단계는 용액이 산성화를 유지한 상태에서 피막이 생성되어 표면으로 부상되는 것을 막고, 반응에 의하 석출물이 생기지 않도록 유지하는 단계이다.The second step is to prevent a film from forming and rising to the surface while the solution is acidified, and to prevent precipitates from forming due to the reaction.
이어, 용기에 연수를 담은 후 연수를 60-70℃로 가열한 상태에서 수산화나트륨을 투입하여 녹여 수산화나트륨 수용액을 만드는 제3단계가 수행된다.Next, the third step is performed in which soft water is placed in a container, heated to 60-70°C, and sodium hydroxide is added and dissolved to create an aqueous sodium hydroxide solution.
이때는 60-70℃로 유지되고 있기 때문에 염이 생기지 않아 고상화가 억제된다.At this time, since it is maintained at 60-70℃, no salt is formed and solidification is suppressed.
이후, 상기 제3단계에서 얻는 수산화나트륨 수용액을 상기 제2단계의 교반기에 투입한 다음 10-20분간 50-60rpm의 속도로 더 교반하는 제4단계가 수행된다.Thereafter, the fourth step is performed in which the sodium hydroxide aqueous solution obtained in the third step is added to the stirrer of the second step and then further stirred at a speed of 50-60 rpm for 10-20 minutes.
그런 다음, 교반액을 포장용기에 담고 상온까지 자연냉각시켜 고화시키는 제5단계가 수행된다.Then, the fifth step is performed in which the stirred liquid is placed in a packaging container and naturally cooled to room temperature to solidify.
즉, 포장 후 자연냉각되는 과정에서 산과 염기가 반응하여 염을 발생시키면서 고화되게 되어 상온에 이르면 안정적인 고체상태를 유지하게 되므로 자연스럽게 용기에 포장된 상태로 굳어 있게 된다.In other words, during the natural cooling process after packaging, the acid and base react to generate salt and solidify, and when it reaches room temperature, it maintains a stable solid state, so it naturally solidifies in the state of being packaged in the container.
따라서, 이송의 편의성, 사용의 편의성, 적재의 편의성 및 안전성을 갖게 된다.Therefore, it provides convenience of transportation, convenience of use, convenience of loading, and safety.
