Description
本発明は、様々な燃料に使用される燃料複合添加剤に関する。 The present invention relates to a composite fuel additive used in various fuels.
産業革命を始め、産業発展の根幹をなした化石燃料(fossil fuel)または石油系燃料(petroleum−based fuel)は、最近、コストアップと資源不足および供給介入の恐れ、環境的な問題のため、石油をベースとした製品に対する代案としてバイオ燃料が特に注目されている。 Fossil fuel or petroleum-based fuel, which has been the basis of industrial development, including the industrial revolution, has recently been due to cost increases, resource shortages and fears of supply intervention, environmental problems, Biofuels are of particular interest as an alternative to oil-based products.
バイオ燃料は、一般的に、バイオマス由来のすべての燃料を意味する。バイオマスは、通常、トウモロコシ、豆、亜麻仁、サトウキビおよびパーム油というような植物性ソースから製造されるが、前記バイオマスはの原料は、一般的に現在生きているすべての有機体、または炭素サイクルで一部分を占めるそれらの代謝副産物にまで拡張することができる。 Biofuel generally means any fuel derived from biomass. Biomass is usually produced from plant sources such as corn, beans, flaxseed, sugarcane and palm oil, but the biomass is generally sourced from all living organisms or the carbon cycle. It can be extended to those metabolic byproducts that occupy part.
既存のバイオマスからバイオエネルギーを生産するための技術および研究として、輸送油であるガソリンおよびディーゼルを代替するための研究が主に進められてきた。ガソリンを代替するために、サトウキビ、トウモロコシなどを醗酵させて製造するバイオブタノールが開発された。 As technology and research for producing bioenergy from existing biomass, research for substituting gasoline and diesel as transport oil has been mainly conducted. In order to replace gasoline, biobutanol, which is produced by fermenting sugarcane, corn, etc., was developed.
しかし、既存のバイオブタノールをそのまま輸送燃料として使用するには、水分混入の問題およびこれに伴う相分離の問題など、石油系燃料に比べて安定性に劣るという限界がある。特に、バイオブタノールは、燃料添加剤として使用する際に、他の燃料添加剤に比べて相分離現象が大幅に生じるという問題がある。 However, in order to use existing biobutanol as a transportation fuel as it is, there is a limit that it is inferior in stability to petroleum-based fuels, such as a problem of water mixing and a phase separation problem associated therewith. In particular, when biobutanol is used as a fuel additive, there is a problem in that a phase separation phenomenon occurs significantly as compared with other fuel additives.
化石燃料または石油系燃料も程度の差があるだけで、依然として水分混入の問題、相分離の問題などが伴われるため、バイオアルコールを始め、新再生燃料および従来のガソリンなどの化石燃料の物理的/化学的安定性をより向上させることができる複合燃料添加剤に関する研究が必要である。 Since fossil fuels or petroleum-based fuels are different to a certain extent and still involve problems of water contamination and phase separation, the physical properties of fossil fuels such as bioalcohol, new renewable fuels and conventional gasoline / Research on composite fuel additives that can further improve chemical stability is needed.
本発明の目的は、高い湿度、低い温度、長期間放置などの劣悪な環境条件でも相分離現象を著しく遅延することができ、より低い融点を有することで冬の凍結を防止するだけでなく、エンジン内に固着化した不純物に対する洗浄効果に優れた燃料複合添加剤を提供することにある。 The object of the present invention is to significantly delay the phase separation phenomenon even under adverse environmental conditions such as high humidity, low temperature, prolonged standing and not only prevent winter freezing by having a lower melting point, An object of the present invention is to provide a fuel composite additive having an excellent cleaning effect against impurities fixed in an engine.
本発明の他の目的は、上述の効果が実現されることで、燃料が、燃料以外の用途に使用されて致命的な問題を起こさないように、例えば、飲み物として使用できなくする燃料複合添加剤を提供することにある。 Another object of the present invention is to achieve the above-mentioned effects, so that the fuel can be used for purposes other than fuel and cause no fatal problems, for example, a fuel compound addition that makes it unusable as a drink.

Handled.
以下、本発明による燃料複合添加剤について詳細に説明する。 Hereinafter, the fuel composite additive according to the present invention will be described in detail.

Descriptions of known functions and configurations that may obscure the gist are omitted.
本発明で使用される用語の単数形態は、特別の指示がない限り、複数形態をも含むものと解釈され得る。 The singular forms of the terms used in the present invention can be construed to include the plural forms as well, unless specifically indicated otherwise.
本発明で特別の断りなく不明に使用された%の単位は、重量%を意味する。 The unit of% used in the present invention for unknown purposes without special notice means weight%.
本発明による燃料複合添加剤は、バイオブタノールと、メチルエチルケトン(Methylethylketone)、メチルイソプロピルケトン(Methylisopropylketone)、メチルイソブチルケトン(Methylisobutylketone)および5−メチル−3−ヘプタノン(5−methyl−3−heptanone)から選択されるいずれか一つまたは二つ以上を含むケトン系化合物と、メチルtert−ブチルエーテル(Methyl tert−butylether)およびエチルtert−ブチルエーテル(Ethyl tert−butylether)から選択されるいずれか一つ以上を含むエーテル系化合物とを含む。 The fuel composite additive according to the present invention is selected from biobutanol, methylethylketone, methylisopropylketone, methylisobutylketone and 5-methyl-3-heptanone. And a ketone compound containing any one or more of the above, and an ether containing any one or more selected from methyl tert-butyl ether and ethyl tert-butyl ether System compounds.
本発明で言及される「バイオブタノール」は、燃料として使用するための公知の一般的なバイオブタノールを意味し、具体的には、バイオマスから燃料として使用するために製造されたブタノールであり、実質的にノルマルブタノールまたはノルマルブタノールを主成分とするブタノール系混合物であってもよい。 The term “biobutanol” referred to in the present invention means a known general biobutanol for use as a fuel, specifically butanol produced for use as a fuel from biomass. In particular, it may be normal butanol or a butanol-based mixture containing normal butanol as a main component.
前記燃料複合添加剤において、ケトン系化合物およびエーテル系化合物は、相分離遅延特性およびエンジン洗浄特性を向上させるための必須の構成成分であり、水分の浸透または混合によって油分層および水分層に相分離される現象を遅延させる特性においてより効果的である。具体的には、本発明による燃料複合添加剤にケトン系化合物およびエーテル系化合物のいずれか一つの系の化合物が単独で使用される場合、相分離遅延特性が小幅に減少するが、本発明のようにケトン系化合物およびエーテル系化合物がいずれも使用される場合、相分離遅延特性が非常に向上し、これと共にエンジン洗浄特性が向上するという効果が実現される。それだけでなく、各成分が混合されることで融点下降が極大化し、冬のなどの温度が非常に低い環境でも凍結を最小化できるという効果があり、後述する他の成分がさらに含まれることで、前記効果はさらに向上することができる。 In the fuel composite additive, the ketone-based compound and the ether-based compound are essential components for improving the phase separation delay characteristic and the engine cleaning characteristic, and phase separation into the oil component layer and the moisture layer by the penetration or mixing of moisture. It is more effective in the property of delaying the phenomenon to be performed. Specifically, when any one compound of a ketone compound and an ether compound is used alone for the fuel composite additive according to the present invention, the phase separation delay characteristic is slightly reduced. Thus, when both a ketone compound and an ether compound are used, the phase separation delay characteristic is greatly improved, and the effect of improving the engine cleaning characteristic is realized. Not only that, the melting point is maximized by mixing each component, and there is an effect that the freezing can be minimized even in an environment where the temperature is very low such as winter, and other components described later are further included. The effect can be further improved.
本発明の一例による燃料複合添加剤は、その組成比を大きく制限しないが、上述の効果を十分に実現するための面で、前記バイオブタノール100重量部に対して、前記ケトン系化合物10〜100重量部および前記エーテル系化合物0.1〜20重量部、より好ましくは、前記ケトン系化合物20〜80重量部および前記エーテル系化合物1〜7重量部を含むことができる。しかし、これは、好ましい一例であって、本発明がこれに制限されないことは言うまでもない。 The fuel composite additive according to an example of the present invention does not greatly limit the composition ratio, but in terms of sufficiently realizing the above effect, the ketone compound 10 to 100 with respect to 100 parts by weight of the biobutanol. It can contain 0.1 to 20 parts by weight of the ether compound, more preferably 20 to 80 parts by weight of the ketone compound and 1 to 7 parts by weight of the ether compound. However, this is a preferable example, and it goes without saying that the present invention is not limited thereto.
より好ましくは、前記ケトン系化合物は、メチルエチルケトン、メチルイソプロピルケトンおよびメチルイソブチルケトンから選択されるいずれか一つまたは二つ以上のC4−C6ケトン系化合物および5−メチル−3−ヘプタノンを含むことが好ましい。具体的には、前記ケトン系化合物において、前記C4−C6ケトン系化合物と5−メチル−3−ヘプタノンがともに使用される場合、相分離現象の抑制においてより効果的であり得る。すなわち、相対的に低い炭素数系のケトン系化合物と高い炭素数のケトン系化合物が併用されることにより、全体の系の自由エネルギーが最小化し、溶存水がミセル(micelle)のような形態で安定して存在することになり、燃料内に高い湿度、低い温度また長期間放置などの劣悪な環境条件でも相分離現象を著しく減少させることができる。 More preferably, the ketone compound includes one or more C4-C6 ketone compounds selected from methyl ethyl ketone, methyl isopropyl ketone, and methyl isobutyl ketone, and 5-methyl-3-heptanone. preferable. Specifically, in the ketone compound, when both the C4-C6 ketone compound and 5-methyl-3-heptanone are used, it can be more effective in suppressing the phase separation phenomenon. In other words, the combined use of a ketone compound having a relatively low carbon number and a ketone compound having a high carbon number minimizes the free energy of the entire system, and the dissolved water is in the form of a micelle. Therefore, the phase separation phenomenon can be remarkably reduced even under poor environmental conditions such as high humidity, low temperature, and long-term standing in the fuel.
本発明の一例による燃料複合添加剤が、前記C4−C6ケトン系化合物および5−メチル−3−ヘプタノンを含む場合、これらの組成比は大きく制限されるものではないが、上述の効果を十分に実現するための面で、前記ケトン系化合物は、前記C4−C6ケトン系化合物100重量部に対して、前記5−メチル−3−ヘプタノン5〜100重量部、好ましくは10〜60重量部含むことができる。しかし、これは、好ましい一例であって、本発明がこれに制限されないことは言うまでもない。 When the fuel composite additive according to an example of the present invention includes the C4-C6 ketone-based compound and 5-methyl-3-heptanone, the composition ratio is not greatly limited, but the above-described effects are sufficiently obtained. In terms of realization, the ketone compound includes 5 to 100 parts by weight, preferably 10 to 60 parts by weight of the 5-methyl-3-heptanone with respect to 100 parts by weight of the C4-C6 ketone compound. Can do. However, this is a preferable example, and it goes without saying that the present invention is not limited thereto.
本発明の一例による燃料複合添加剤は、tert−ブタノール(tert−butanol)および/またはデナトニウムベンゾエート(Denatonium benzoate)をさらに含んでもよく、好ましくは、tert−ブタノールとデナトニウムベンゾエートをいずれも含むことが好ましい。具体的には、前記燃料複合添加剤がtert−ブタノールおよびデナトニウムベンゾエートをともに含む場合、これらが単独でそれぞれ含まれる場合と比較して、相分離遅延特性およびエンジン洗浄特性が著しく向上することができる。tert−ブタノールの立体障害が塩の状態で存在するデナトニウムベンゾエートとともに混合されることで、相分離遅延特性およびエンジン洗浄特性のいずれもが著しく向上することができる。 The fuel composite additive according to an example of the present invention may further include tert-butanol and / or denatonium benzoate, and preferably includes both tert-butanol and denatonium benzoate. Is preferred. Specifically, when the fuel composite additive includes both tert-butanol and denatonium benzoate, the phase separation delay characteristic and the engine cleaning characteristic may be significantly improved as compared with the case where these are included alone, respectively. it can. By mixing the steric hindrance of tert-butanol with the denatonium benzoate present in the salt state, both the phase separation delay characteristic and the engine washing characteristic can be remarkably improved.
また、本発明の一例による燃料複合添加剤は、デナトニウムベンゾエートを含む場合、特異な香および味を出すため、燃料が、燃料以外の用途に使用されないようにする効果がある。 In addition, when the fuel composite additive according to an example of the present invention contains denatonium benzoate, it has an effect of preventing the fuel from being used for purposes other than the fuel because it has a unique aroma and taste.
本発明の一例による燃料複合添加剤がtert−ブタノールを含む場合、その組成比は、大きく制限されず、例えば、前記バイオブタノール100重量部に対して、前記tert−ブタノール10〜100重量部、好ましくは15〜60重量部で含むことができる。しかし、これは、好ましい一例であって、本発明がこれに制限されないことは言うまでもない。 When the fuel composite additive according to an example of the present invention includes tert-butanol, the composition ratio is not greatly limited, and for example, 10 to 100 parts by weight of the tert-butanol, preferably 100 parts by weight of the biobutanol. May be included at 15-60 parts by weight. However, this is a preferable example, and it goes without saying that the present invention is not limited thereto.
本発明の一例による燃料複合添加剤がデナトニウムベンゾエートを含む場合、その組成比は大きく制限されず、例えば、前記バイオブタノール100重量部に対して、前記デナトニウムベンゾエート0.001〜1重量部、好ましくは、0.001〜0.5重量部含むことができる。しかし、これは、好ましい一例であって、本発明がこれに制限されないことは言うまでもない。 When the fuel composite additive according to an example of the present invention includes denatonium benzoate, the composition ratio is not greatly limited. For example, 0.001 to 1 part by weight of the denatonium benzoate with respect to 100 parts by weight of the biobutanol, Preferably, it can contain 0.001-0.5 weight part. However, this is a preferable example, and it goes without saying that the present invention is not limited thereto.
本発明の一例による燃料複合添加剤がtert−ブタノールおよびデナトニウムベンゾエートを含む場合、その組成比は大きく制限されないが、上述の効果を十分に実現するための面で、前記燃料複合添加剤は、前記バイオブタノール100重量部に対して、前記tert−ブタノール10〜100重量部および前記デナトニウムベンゾエート0.001〜1重量部、好ましくは、前記tert−ブタノール15〜60重量部および前記デナトニウムベンゾエート0.001〜0.5重量部を含むことができる。しかし、これは、好ましい一例であって、本発明がこれに制限されないことは言うまでもない。 When the fuel composite additive according to an example of the present invention includes tert-butanol and denatonium benzoate, the composition ratio is not greatly limited. However, in terms of sufficiently realizing the above-described effect, the fuel composite additive includes: 10 to 100 parts by weight of the tert-butanol and 0.001 to 1 part by weight of the denatonium benzoate, preferably 15 to 60 parts by weight of the tert-butanol and the denatonium benzoate 0 to 100 parts by weight of the biobutanol. 0.001 to 0.5 parts by weight may be included. However, this is a preferable example, and it goes without saying that the present invention is not limited thereto.

相分離遅延特性の評価
実施例1〜実施例6、比較例1および比較例2それぞれの燃料複合添加剤を下記方法で実験し、相分離遅延程度を評価した。
Evaluation of Phase Separation Delay Characteristics The fuel composite additives in Examples 1 to 6, Comparative Example 1 and Comparative Example 2 were tested by the following method to evaluate the degree of phase separation delay.
具体的には、それぞれの100ml試験管にそれぞれの燃料複合添加剤を投入し、水分(0.05%、0.1%、0.15%、0.20%、0.25%、0.30%、0.35%、0.40%、0.45%、0.50%)をそれぞれさらに投入して激しく振盪して水分を強制に混入させた後、10分間放置し、変化する層を確認した。また、最終的に明らかな層分離を確認するために、20℃で1,500rpmで10分間遠心分離し、試験管に発生した層のスケールを測定した。 Specifically, each fuel composite additive is put into each 100 ml test tube, and moisture (0.05%, 0.1%, 0.15%, 0.20%, 0.25%,. 30%, 0.35%, 0.40%, 0.45%, 0.50%), and vigorously shaken to forcibly mix moisture, and then left for 10 minutes to change the layer. It was confirmed. In addition, in order to finally confirm clear layer separation, the mixture was centrifuged at 1,500 rpm for 10 minutes at 20 ° C., and the scale of the layer generated in the test tube was measured.
前記表2のように、ケトン系化合物およびエーテル系化合物のいずれか一つの系のみ単独で使用された比較例1および比較例2の場合は、相分離遅延特性が最も良好でない一方、ケトン系化合物およびエーテル系化合物がともに使用された実施例1〜実施例6の場合は、相分離遅延特性が著しく向上した。 As shown in Table 2, in the case of Comparative Example 1 and Comparative Example 2 in which only one of the ketone compound and the ether compound was used alone, the phase separation delay characteristic was not the best, while the ketone compound In Examples 1 to 6 in which both the ether compound and the ether compound were used, the phase separation delay characteristics were remarkably improved.
C4−C6ケトン系化合物およびC8ケトン系化合物(5−メチル−3−ヘプタノン)のいずれか一つの系のみ単独で使用された実施例1および実施例2の場合よりも、これらの系がいずれも使用された実施例3〜実施例6の場合が、相分離遅延特性がより高かった。 These systems are both more than in the case of Example 1 and Example 2 in which only one of the C4-C6 ketone compound and the C8 ketone compound (5-methyl-3-heptanone) is used alone. In the case of Example 3 to Example 6 used, the phase separation delay characteristic was higher.
前記表2の実施例3および実施例4の場合より、tert−ブタノール単独は、相分離遅延特性にそれほど影響を与えないことが分かる。また、前記表2の実施例5および実施例6の場合より、デナトニウムベンゾエートは、tert−ブタノールとともに使用されるときに、相分離遅延特性が著しく向上することが分かる。かかる結果は、tert−ブタノールの立体的特性とデナトニウムベンゾエートの塩特性がともに複合作用し、組成物の相分離を大幅に抑制したものと考えられる。 From the cases of Example 3 and Example 4 in Table 2, it can be seen that tert-butanol alone does not significantly affect the phase separation delay characteristics. In addition, from the cases of Example 5 and Example 6 in Table 2, it can be seen that denatonium benzoate significantly improves the phase separation delay characteristics when used with tert-butanol. Such a result is considered that the steric characteristics of tert-butanol and the salt characteristics of denatonium benzoate both acted together to greatly suppress the phase separation of the composition.
エンジン洗浄特性の評価
実施例1〜実施例6、比較例1および比較例2それぞれの燃料複合添加剤をガソリンに1重量%添加する下記方法で実験し、エンジン洗浄特性程度を評価した。
Evaluation of Engine Cleaning Characteristics Experiments were conducted by the following method in which 1% by weight of each of the fuel composite additives of Examples 1 to 6, Comparative Example 1 and Comparative Example 2 was added to gasoline, and the degree of engine cleaning characteristics was evaluated.
具体的には、前記実験は、SAE(Society for Automotive Engineers)によって出刊された文献の参照番号SAE # 922184(1992)に記述の方法によるガソリンエンジンテスト方式で行われた。この際、各実験は、3,000rpmのエンジン速度および最大荷重の2/3の条件下で、5時間行われた。各実験が開始する時、エンジンに新しいインジェクターを装着し、インジェクターを装着する前に各インジェクターの放出量をそれぞれのニードルリフト(needle lift)で測定した。各実験完了段階でインジェクターを分離し、同じニードルリフトの間の放出量を測定した。実験されたそれぞれの燃料複合添加剤の効率を残留物放出パーセントとして比較し、これは、以下のような式1により計算した。その結果は下記表2に図示しており、放出量が高いほどエンジン洗浄効果に優れていることを意味する。 Specifically, the experiment was conducted in a gasoline engine test system according to the method described in the reference number SAE # 922184 (1992) published by SAE (Society for Automotive Engineers). At this time, each experiment was performed for 5 hours under the condition of an engine speed of 3,000 rpm and 2/3 of the maximum load. At the start of each experiment, a new injector was attached to the engine, and the amount of discharge from each injector was measured with the respective needle lift before the injector was attached. At the completion of each experiment, the injector was separated and the amount released during the same needle lift was measured. The efficiency of each fuel composite additive tested was compared as a percent residue release, which was calculated by Equation 1 as follows: The results are shown in Table 2 below, and the higher the release amount, the better the engine cleaning effect.
[式1]
残留物放出量(%)=(テスト完了時のインジェクターの平均放出量/新しいインジェクターの平均放出量)×100
[Formula 1]
Residue release (%) = (average injector discharge at the completion of the test / average injector new discharge) × 100
前記表3のように、ケトン系化合物およびエーテル系化合物のいずれか一つの系のみ単独で使用された比較例1および比較例2の場合は、エンジン洗浄特性が最も良好でない一方、ケトン系化合物およびエーテル系化合物がともに使用された実施例1〜実施例6の場合は、エンジン洗浄特性が著しく向上した。 As shown in Table 3, in Comparative Example 1 and Comparative Example 2 in which only one of a ketone compound and an ether compound was used alone, the engine cleaning characteristics were not the best, while the ketone compound and In the case of Examples 1 to 6 where both ether compounds were used, the engine cleaning characteristics were remarkably improved.
実施例4の場合のように、tert−ブタノールが単独で加えられる場合、エンジン洗浄特性に大きく影響がなかったが、デナトニウムベンゾエートが単独で加えられる場合、エンジン洗浄特性が向上し、特に、デナトニウムベンゾエートとtert−ブタノールがともに使用される場合、デナトニウムベンゾエートが単独で加えられた場合よりもエンジン洗浄特性が著しく向上することを前記表3から確認することができる。
When tert-butanol was added alone as in Example 4, the engine cleaning characteristics were not significantly affected. However, when denatonium benzoate was added alone, the engine cleaning characteristics were improved. It can be seen from Table 3 that the engine cleaning properties are significantly improved when both tonium benzoate and tert-butanol are used than when denatonium benzoate is added alone.
