Description
本発明は、芳香族分とオレフィン分の含有量を低減させ、オクタン価を９２以上に高めたガソリン組成物に関する。 The present invention relates to a gasoline composition in which the aromatic content and olefin content are reduced and the octane number is increased to 92 or more.
ガソリンは、通常、接触改質ガソリン、接触分解ガソリン、アルキレートガソリン、ライトナフサ、異性化ガソリン等の各種石油系炭化水素の基材をブレンドして製造され、数百種類の化合物の混合物である。これらの化合物は、大きくは飽和分、オレフィン分、芳香族分に分類でき、オクタン価を高くするため、芳香族分、オレフィン分を適当量含むように製造される。 Gasoline is usually produced by blending various petroleum hydrocarbon base materials such as catalytically reformed gasoline, catalytic cracked gasoline, alkylate gasoline, light naphtha, isomerized gasoline, etc., and is a mixture of several hundred kinds of compounds. . These compounds can be roughly classified into a saturated content, an olefin content, and an aromatic content, and are produced so as to contain appropriate amounts of an aromatic content and an olefin content in order to increase the octane number.
ところで、地球温暖化対策が世界的な課題で、二酸化炭素の削減が急務となっており、自動車の燃費改善のためガソリンのオクタン価を上げることが要望されている。このオクタン価を上げる方法として、トルエン等の芳香族分やオレフィン分の配合割合を増やすことが一般的であるが、芳香族分はオクタン価は高いが、燃焼性が悪く、エンジン内のデポジットの原因になることが知られている。また、オレフィン分もオクタン価が高いが、安定性が悪く、ガム状物質を増加させ、インジェクターを詰まらせる等の不具合が発生する可能性があると指摘されている。 By the way, global warming countermeasures are a global issue, and the reduction of carbon dioxide is an urgent issue, and there is a demand for increasing the octane number of gasoline in order to improve automobile fuel efficiency. As a method of increasing the octane number, it is common to increase the blending ratio of aromatic components such as toluene and olefins, but the aromatic component has a high octane number, but it is poor in flammability and causes deposits in the engine. It is known to be. In addition, although the olefin content is also high in octane number, it is pointed out that there is a possibility of problems such as poor stability, increased gum-like substances, and clogging injectors.
また、エタノールやその誘導体であるエチルターシャリーブチルエーテル（ETBE）、或いはメチルターシャリーブチルエーテル（MTBE）の含酸素化合物を配合することにより、重質留分、芳香族分やオレフィン分等をある程度低減させてもオクタン価を維持したガソリンが提案されている（例えば、特許文献１〜３参照）。
しかし、これらの含酸素化合物を単に配合するだけではオクタン価を高めて芳香族分やオレフィン分を大幅に減らすことは容易ではなかった。
すなわち、本発明はかかる課題を解決するもので、本発明の目的は芳香族分やオレフィン分を大幅に低減できて、なおオクタン価を高めたガソリン組成物を提供することにある。
However, it is not easy to increase the octane number and greatly reduce the aromatic content and olefin content simply by blending these oxygen-containing compounds.
That is, the present invention solves this problem, and an object of the present invention is to provide a gasoline composition that can greatly reduce aromatic content and olefin content and that has an increased octane number.
本発明者は鋭意研究を重ねた結果、特定の飽和分とトリメチルペンタンを所定量含み、この成分の比がある範囲になるようにして、含酸素化合物を配合することにより、芳香族分とオレフィン分を大幅に低減できるとの知見を得て、本発明に想到した。 As a result of earnest research, the present inventor has included a predetermined amount of a specific saturated component and trimethylpentane, and blended an oxygen-containing compound so that the ratio of this component is within a certain range, whereby an aromatic component and an olefin are mixed.
