【摘要】：根據(jù)汽油詳細烴組成模擬計算了典型成品汽油不同餾分段的研究法辛烷值,獲得了汽油餾分不同類型組分辛烷值和沸點分布的關系以及對樣品辛烷值的貢獻率。結果表明,不同類型組分辛烷值貢獻率由大到小的順序依次為芳烴、異構烷烴、烯烴、甲基叔丁基醚(MTBE)、環(huán)烷烴和正構烷烴。92#汽油辛烷值按照沸點的分布,呈現(xiàn)出兩頭大、中間小的特點。其中小于60℃的輕端餾分辛烷值的貢獻主要來源于烯烴組分,大于120℃餾分段的辛烷值貢獻主要來源于芳烴組分。90~120℃餾分有最低的辛烷值,60~90℃餾分有最低的辛烷值貢獻率。加入一定量的烷基化汽油后,可以提高90~120℃餾分的辛烷值,改善汽油辛烷值的分布。
[Abstract]:According to the detailed hydrocarbon composition of gasoline, the research octane number of different fractions of typical finished gasoline was calculated, and the relationship between octane number and boiling point distribution of different types of gasoline fractions and the contribution rate to the octane number of the sample were obtained. The octane number contribution rates of different types of components are in the order of aromatics, iso-alkanes, alkenes, methyl tert-#china_person0# ether MTBEBEN, cycloalkanes and n-alkanes .92# gasoline octane numbers distributed according to boiling point, showing two big octane numbers. The contribution of octane number of light end fraction less than 60 鈩，
