Abstract
Description
本発明は、家庭用暖房機器の燃料などに使用される灯油組成物に関するものである。 The present invention relates to a kerosene composition used as a fuel for household heating equipment.
家庭用暖房機器は、年間の限られた期間にのみ使用される場合が殆どであり、その使用期間に消費されなかった燃料は、通常、翌年の使用期まで容器に収容され保存されることが多い。そのため、家庭用暖房機器の燃料として使用される灯油組成物には、使用されずに保存されている間も品質が維持される安定性が必要となる。そして、保存期間における品質維持には酸化安定性が重要な指標となる。 Household heating appliances are mostly used only for a limited period of the year, and fuel that is not consumed during the period of use is usually stored and stored in containers until the next year of use. Many. Therefore, the kerosene composition used as a fuel for home heating equipment needs to be stable so that the quality is maintained even when stored without being used. Oxidation stability is an important index for maintaining quality during the storage period.
酸化安定性は、例えば、特許文献１（特開２００６−２３３０８７）、特許文献２（特開２００７−７７３５５）に、灯油組成物の組成を所定の範囲にすることで、酸化安定性を向上させる技術が開示されている。 For example, Patent Document 1 (Japanese Patent Laid-Open No. 2006-233087) and Patent Document 2 (Japanese Patent Laid-Open No. 2007-77355) improve the oxidation stability by setting the composition of the kerosene composition within a predetermined range. Technology is disclosed.
一方、家庭用暖房機器は一般住居で使用されることが想定されていることから、その燃料として使用される灯油組成物には、特別な知識を要することなく安全かつ快適に利用することを可能とする性能が求められている。すなわち、燃焼性に優れ煙が出にくいものであることが求められている。 On the other hand, since it is assumed that household heating equipment is used in ordinary residences, the kerosene composition used as the fuel can be used safely and comfortably without requiring special knowledge. Performance is required. That is, it is required to be excellent in combustibility and difficult to emit smoke.
また、燃料補給の手間や燃料補給操作により事故が発生する危険性を低減するとともに、コストの観点から、燃費の良いものであること、換言すれば発熱量の高いものであることが求められている。 In addition to reducing the risk of accidents due to refueling operations and refueling operations, from the viewpoint of cost, it is required to have good fuel consumption, in other words, high heat generation. Yes.
しかしながら、酸化安定性を向上させるための従来の技術では、酸化安定性とともに燃焼性と発熱量についても市場で要求される性能を満たす灯油組成物を製造することは難しい。 However, it is difficult to produce a kerosene composition that satisfies the performance required in the market with respect to oxidation stability as well as flammability and calorific value with conventional techniques for improving oxidation stability.
そこで、本発明は、酸化安定性とともに燃焼性と発熱量についても優れた灯油組成物を提供することを目的とする。 Therefore, an object of the present invention is to provide a kerosene composition that is excellent in oxidation stability, combustibility and calorific value.
以上の目的を達成するために、本発明者らは、鋭意研究を重ねた結果、酸化安定性とともに燃焼性と発熱量についても優れた灯油組成物を見出した。すなわち、本発明は、密度が０．７９００〜０．８１００ｇ／ｃｍ３、硫黄分が１０ｐｐｍ以下、及び煙点が２１．０ｍｍ以上で、芳香族分の含有量が２１．０〜２７．０ｍａｓｓ％、及びインダン類の含有量が５．９ｍａｓｓ％以下である灯油組成物である。 In order to achieve the above-mentioned object, the present inventors have conducted keen research, and as a result, have found a kerosene composition that is excellent not only in oxidation stability but also in combustibility and calorific value. That is, the present invention has a density of 0.7900 to 0.8100 g / cm 3 , a sulfur content of 10 ppm or less, a smoke point of 21.0 mm or more, and an aromatic content of 21.0 to 27.0 mass%. And the kerosene composition whose content of indans is 5.9 mass% or less.
本発明によれば、酸化安定性とともに燃焼性と発熱量についても優れた灯油組成物を提供することができる。 According to the present invention, it is possible to provide a kerosene composition that is excellent in terms of oxidation stability, combustibility and calorific value.
本発明に係る灯油組成物は、芳香族分を含む。芳香族分としては、例えば、インダン類やテトラリン類などの、ベンゼンにアルキル基やナフテン環を有する１環芳香族分、ナフタレンにアルキル基やナフテン環を有する２環芳香族分、及びフェナントレンやアントラセンにアルキル基やナフテン環を有する３環芳香族分が挙げられる。本発明に係る灯油組成物は、芳香族分を２１．０〜２７．０ｍａｓｓ％、好ましくは２１．０〜２５．０ｍａｓｓ％、さらに好ましくは２１．０〜２３．０ｍａｓｓ％含む。芳香族分が少ないと発熱量が低くなることがあり、多いと燃焼の際にすすが出やすくなる。 The kerosene composition according to the present invention contains an aromatic component. The aromatic component includes, for example, indane and tetralin, one-ring aromatic component having an alkyl group or naphthene ring in benzene, two-ring aromatic component having an alkyl group or naphthene ring in naphthalene, and phenanthrene or anthracene. Includes a tricyclic aromatic group having an alkyl group or a naphthene ring. The kerosene composition according to the present invention contains an aromatic content of 21.0 to 27.0 mass%, preferably 21.0 to 25.0 mass%, more preferably 21.0 to 23.0 mass%. If the aromatic content is low, the calorific value may be low, and if it is high, soot is likely to be generated during combustion.
本発明に係る灯油組成物は、インダン類を含む。インダン類とは、インダン及びインダンに１以上のアルキル基を有するもので、例えば、インダン、メチルインダン、ジメチルインダン、及びトリメチルインダンなどが挙げられる。本発明に係る灯油組成物は、インダン類を５．９ｍａｓｓ％以下含み、好ましくは５．５ｍａｓｓ％以下、より好ましくは４．０ｍａｓｓ％以下、更に好ましくは２．５ｍａｓｓ％以下である。インダン類が多いと、酸化安定性が悪くなるが、製造コストの観点からは、１．０ｍａｓｓ％以上含まれていてもよい。 The kerosene composition according to the present invention contains indanes. Indans are those having one or more alkyl groups in indane and indane, and examples thereof include indane, methylindane, dimethylindane, and trimethylindan. The kerosene composition according to the present invention contains 5.9 mass% or less of indans, preferably 5.5 mass% or less, more preferably 4.0 mass% or less, and even more preferably 2.5 mass% or less. When there are many indanes, oxidation stability will worsen, but from a viewpoint of manufacturing cost, 1.0 mass% or more may be contained.
インダンは、灯油組成物中に４．０ｍａｓｓ％以下であることが好ましく、３．０ｍａｓｓ％以下であることがより好ましく、２．５ｍａｓｓ％以下であることが更に好ましく、０．５ｍａｓｓ％以下であることが特に好ましい。インダンは、インダン類の中でも特に酸化安定性に影響を与えるため、少ない方が好ましいが、製造コストの観点からは、０．１ｍａｓｓ％以上含まれていてもよい。 Indan is preferably 4.0 mass% or less in the kerosene composition, more preferably 3.0 mass% or less, still more preferably 2.5 mass% or less, and 0.5 mass% or less. It is particularly preferred. Indan is particularly preferable among indanes because it affects the oxidative stability. However, from the viewpoint of production cost, it may be contained in an amount of 0.1 mass% or more.
本発明に係る灯油組成物は、テトラリン類を含んでいてもよい。テトラリン類とは、テトラリン及びテトラリンに１以上のアルキル基を有するもので、例えば、テトラリン、及びメチルテトラリンが挙げられる。テトラリン類は、灯油組成物の酸化安定性に大きな影響を与えないため、含有量は多くてもよいが、燃焼性の観点からは、好ましくは７．０ｍａｓｓ％以下、より好ましくは６．０ｍａｓｓ％以下、更に好ましくは５．０ｍａｓｓ％以下であるが、製造コストの観点からは、０．１ｍａｓｓ％以上含まれていてもよい。 The kerosene composition according to the present invention may contain tetralins. Tetralins are those having one or more alkyl groups in tetralin and tetralin, and examples include tetralin and methyltetralin. Tetralins do not significantly affect the oxidation stability of the kerosene composition, so the content may be large, but from the viewpoint of combustibility, it is preferably 7.0 mass% or less, more preferably 6.0 mass%. Hereinafter, it is more preferably 5.0 mass% or less, but from the viewpoint of manufacturing cost, it may be contained by 0.1 mass% or more.
本発明に係る灯油組成物は、質量比（インダン類）／（芳香族分）が好ましくは０．０５〜０．２３、より好ましくは０．０５〜０．１５である。酸化安定性の観点からは、質量比（インダン類）／（芳香族分）は小さい方が好ましい。 The kerosene composition according to the present invention preferably has a mass ratio (indanes) / (aromatic content) of 0.05 to 0.23, more preferably 0.05 to 0.15. From the viewpoint of oxidation stability, a smaller mass ratio (indanes) / (aromatic content) is preferable.
本発明に係る灯油組成物は、原油を蒸留して得られる灯油留分と流動接触分解装置から留出する分解灯油留分を混合し、脱硫処理して得ることが好ましい。分解灯油留分には、インダン類やテトラリン類などのナフテノベンゼン類が多く含まれる。そのため、上述のようなインダン類の含有量とすることにより、分解灯油留分を有効に利用することができる。２０１４年７月末に改正された「エネルギー供給構造高度化法」の新たな判断基準により、製油所では直留系基材に対する分解系基材の比率が更に増加することが見込まれている。特に、分解ガソリンの重質分（分解灯油留分）の一部から灯油を製造するルートは、ガソリン需要の減少が想定されるなか、灯油生産に振り替えることが出来るので大変重要である。灯油組成物中、分解灯油留分は、好ましくは０〜２０容量％、より好ましくは２〜２０容量％、さらに好ましくは４〜２０容量％である。分解灯油留分は、灯油生産に振り替えることができるので多い方が好ましいが、多すぎると酸化安定性など灯油としての優れた性状を得ることが難しくなる。 The kerosene composition according to the present invention is preferably obtained by mixing a kerosene fraction obtained by distilling crude oil with a cracked kerosene fraction distilled from a fluid catalytic cracking apparatus and subjecting it to a desulfurization treatment. The cracked kerosene fraction is rich in naphthenobenzenes such as indanes and tetralins. Therefore, the decomposition kerosene fraction can be used effectively by setting the content of indans as described above. In accordance with the new criteria of the “Energy Supply Structure Advancement Law” revised at the end of July 2014, the refinery is expected to further increase the ratio of cracked base materials to straight-run base materials. In particular, the route for producing kerosene from a portion of the heavier portion of cracked gasoline (cracked kerosene fraction) is very important because it can be transferred to kerosene production amid the expected decrease in gasoline demand. In the kerosene composition, the cracked kerosene fraction is preferably 0 to 20% by volume, more preferably 2 to 20% by volume, and further preferably 4 to 20% by volume. The cracked kerosene fraction can be transferred to kerosene production, so it is preferable that it is large. However, if it is too much, it becomes difficult to obtain excellent properties as kerosene such as oxidation stability.
本発明に係る灯油組成物は、硫黄分が１０ｐｐｍ以下であり、好ましくは８ｐｐｍ以下である。硫黄分含有量は、少ないほど、人間にとって不快な臭気が少なくなる。また、少なすぎると酸化安定性が悪くなることがあり製造コストも高くなるので、３ｐｐｍ以上が好ましい。 The kerosene composition according to the present invention has a sulfur content of 10 ppm or less, preferably 8 ppm or less. The lower the sulfur content, the less unpleasant odor for humans. Moreover, since oxidation stability may worsen and manufacturing cost will become high when there are too few, 3 ppm or more is preferable.
本発明に係る灯油組成物は、密度が０．７９００〜０．８１００ｇ／ｃｍ３であり、好ましくは０．７９２０〜０．８０４０ｇ／ｃｍ３であり、より好ましくは０．７９５０〜０．８０００ｇ／ｃｍ３である。密度が高くなると燃焼性が悪化することがある。ただし、密度が低いと暖房性に支障が出る可能性がある。 The kerosene composition according to the present invention has a density of 0.7900 to 0.8100 g / cm 3 , preferably 0.7920 to 0.8040 g / cm 3 , and more preferably 0.7950 to 0.8000 g / cm 3. cm 3 . When the density increases, the flammability may deteriorate. However, if the density is low, there is a possibility that the heating performance may be hindered.
本発明に係る灯油組成物は、蒸留性状初留点が１４０．０℃〜１７０．０℃であることが好ましい。１０％留出温度は、１６０．０℃〜１８０．０℃であることが好ましい。９５％留出温度は２３０．０℃〜２７０．０℃であることが好ましい。各留出温度が上記範囲よりも低い場合、芯式・放射形石油ストーブ最大燃焼使用時において、火足が伸び過ぎ、消火時間が長くなり安全な燃焼状態が保てず、また、燃料消費量も増加し経済性もよくないため好ましくない。上記範囲よりも高い場合は、着火性が悪くなるなどの問題が生じる可能性があり好ましくない。安全な燃焼状態のために、より好ましくは初留点が１４５．０℃〜１６０．０℃、１０％留出温度が１６５．０℃〜１７５．０℃、９５％留出温度が２４０．０℃〜２５０．０℃である。なお、上記蒸留性状以外に、例えば、５０％留出温度が１８０．０℃〜２２０．０℃、９０％留出温度が２３０．０℃〜２４５．０℃とすることができる。 The kerosene composition according to the present invention preferably has a distillation property initial boiling point of 140.0 ° C to 170.0 ° C. The 10% distillation temperature is preferably 160.0 ° C to 180.0 ° C. The 95% distillation temperature is preferably 230.0 ° C to 270.0 ° C. When each distillation temperature is lower than the above range, when using a core type / radial oil stove maximum combustion, the fire foot is extended too much, the fire extinguishing time becomes long and the safe combustion state cannot be maintained, and the fuel consumption Increase and the economic efficiency is not good. If it is higher than the above range, problems such as poor ignitability may occur, which is not preferable. For safe combustion, more preferably, the initial boiling point is 145.0 ° C to 160.0 ° C, the 10% distillation temperature is 165.0 ° C to 175.0 ° C, and the 95% distillation temperature is 240.0. It is 25 degreeC-250.0 degreeC. In addition to the above distillation properties, for example, the 50% distillation temperature can be 180.0 ° C to 220.0 ° C, and the 90% distillation temperature can be 230.0 ° C to 245.0 ° C.
本発明に係る灯油組成物は、燃焼性などの観点から、煙点が２１．０ｍｍ以上、好ましくは２１．０ｍｍ〜２４．０ｍｍ、より好ましくは２１．０ｍｍ〜２３．０ｍｍである。 The kerosene composition according to the present invention has a smoke point of 21.0 mm or more, preferably 21.0 mm to 24.0 mm, more preferably 21.0 mm to 23.0 mm from the viewpoint of combustibility.
本発明に係る灯油組成物は、ＰｅｔｒｏＯＸＹ誘導期間が好ましくは６５ｍｉｎ以上、より好ましくは７５ｍｉｎ以上、更に好ましくは９０ｍｉｎ以上である。 The kerosene composition according to the present invention preferably has a PetroOXY induction period of 65 min or more, more preferably 75 min or more, and still more preferably 90 min or more.

本発明に係る灯油組成物は、例えば、原油を精製する工程で得られる各種石油留分を分解・合成・配合することで得ることができる。インダン類やテトラリン類の含有量は、原油を蒸留して得られる灯油留分や分解灯油の蒸留性状、これら原料油を脱硫する時の脱硫条件、灯油留分や分解軽油の混合量などを適宜、調節、脱硫することにより適切な範囲とすることができる。また、ＧＴＬ灯油を脱硫装置の原料又は脱硫後の灯油に適宜混合することにより得ることもできる。 The kerosene composition according to the present invention can be obtained, for example, by decomposing, synthesizing and blending various petroleum fractions obtained in the process of refining crude oil. The content of indans and tetralins should be adjusted appropriately depending on the distillation characteristics of kerosene fractions and cracked kerosene obtained by distilling crude oil, desulfurization conditions when desulfurizing these raw oils, and the mixing amount of kerosene fractions and cracked light oil. By adjusting and desulfurizing, an appropriate range can be obtained. It can also be obtained by appropriately mixing GTL kerosene with the raw material of the desulfurization apparatus or kerosene after desulfurization.
