Description

表７及び表８に示すように、実施例１〜１２は、何れも従来のＦＴ軽油である参考例と比較し、体積変化率が増加している。従って、表４〜６とこれらの結果から、炭素数１５以下のパラフィン含有量の割合を２８容量％以上、且つ、炭素数１８以上のノルマルパラフィンの割合を１１容量％以下とすることで、実質的にパラフィンのみで構成される軽油燃料組成物であっても、ゴム膨潤性を改良できることが確認できた。なお、実施例２、実施例３及び実施例１２のピーク総面積の割合は、参考例よりも低くなっているが、炭素数１５以下のパラフィン含有量、炭素数１８以上のノルマルパラフィン含有量が本発明の条件を満たすため、体積変化率は比較例或いは参考例よりも増加している。すなわち、体積変化率の増加の観点からイソパラフィンの割合の高いことが好ましい点は上記のとおりであるが、たとえパラフィンのプロトン核磁気共鳴スペクトルにおけるピーク総面積の割合が比較例や参考例よりも低くても、炭素数１５以下のパラフィン含有量の割合と炭素数１８以上のノルマルパラフィンの割合が本発明の条件を満たしていれば、体積変化率の増加を図ることが確認できた。 As shown in Table 7 and Table 8, in Examples 1 to 12, the volume change rate is increased as compared with the reference example which is a conventional FT light oil. Therefore, from Tables 4 to 6 and these results, the ratio of the paraffin content having 15 or less carbon atoms is 28% by volume or more, and the ratio of the normal paraffin having 18 or more carbon atoms is 11% by volume or less. In particular, it was confirmed that even a light oil fuel composition composed only of paraffin can improve rubber swellability. The ratio of the total peak area of Example 2, Example 3 and Example 12 is lower than the ginseng Reference Example, the number 15 following paraffin content of carbon, normal paraffin content having 18 or more carbon atoms However, since the conditions of the present invention are satisfied, the volume change rate is higher than that of the comparative example or the reference example. That is, from the viewpoint of increasing the volume change rate, it is preferable that the ratio of isoparaffin is high as described above. However, if the ratio of the paraffin content having 15 or less carbon atoms and the ratio of the normal paraffin having 18 or more carbon atoms satisfy the conditions of the present invention, it was confirmed that the volume change rate was increased.

更に、表７及び表８に示すように、蒸留性状およびプロトン核磁気共鳴スペクトルにおけるピーク総面積の割合の関係が、上記式（１）で得られるＺ値が−３．５より大きいことを満たすものであれば、従来のＦＴ軽油よりも体積変化率の改善が図られることが確認できた。 Furthermore, as shown in Table 7 and Table 8 , the relationship between the distillation property and the ratio of the total peak area in the proton nuclear magnetic resonance spectrum satisfies that the Z value obtained by the above formula (1) is larger than −3.5. It can be confirmed that the volume change rate can be improved as compared with the conventional FT light oil.
