| 摘 要： | 以常用理化指标,如馏程、密度、芳香烃含量和烯烃含量、溴价为参数,提出计算汽油马达法辛烷值和
研究法辛烷值的公式。通过对大量炼厂和文献数据进行验证,结果表明,研究法辛烷值的计算结果中,70%的样品
误差小于1.2;马达法辛烷值的计算结果中,81%的样品误差小于1.8,说明公式可以用于辛烷值的计算,公式误差符
合标准要求。公式具有适用范围广、计算快捷方便等优点,对炼油生产过程中的产品质量控制具有一定的参考价
值。

| Abstract: | Using common quality specifications,the prediction equations for calculation motor octane number(MON) and research octane number(RON) were proposed,including distillation range,density,aromatic content,and olefinic content or bromine value.From a large number of refineries and literature data,about 70% of the sample error is less than 1.2 when MON is calculated directly by means of these prediction equations,and more than 81% of error is less than 1.8 by RON being calculated.Therefore,the ON can be calculat... |
