摘　　要：分析了汽油池的主要调合组分以及作为清洁燃料组分的烷基化汽油的单体烃组成特点,探讨了S Zorb汽油、催化重整汽油、烷基化汽油3种汽油调合组分的辛烷值分布规律及对辛烷值贡献较大的单体烃组成,并对汽油调合规律进行了较为深入的分析。结果表明:在相同辛烷值、相同芳烃含量的情况下,可以调合出单体烃组成不同的汽油;在保证相同蒸气压的前提下可以调合出馏程分布不同的汽油。Gasoline is a complex mixture of hydrocarbons composed by a variety of different monomer composition.Monomer hydrocarbon compositions of the main gasoline blending components in gasoline pool as well as alkylation gasoline alone are discussed.The octane number distribution of three gasoline blending components,i.e.S Zorb gasoline,reformate and alkylate,and the monomer hydrocarbons making a larger contribution to the octane number are also analyzed.The regularity of gasoline blending is analyzed in detail.It follows that the gasoline formulations with different monomer hydrocarbon composition can be made at the same octane number and total aromatic content.In addition,the gasoline with different boiling range can also be blended on the premise of equal vapor pressure.
