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。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 calculated by these equations.It shows that the error of the prediction equations meet the standard requirement.The equations are a rapid,simple and wide-application method for the calculation of ON.They have something referential values for product quality control in petroleum refinery operation.
