摘　　要：采用体积切割法分析研究了出口汽油硫含量在馏分中的分布。结果表明:窄馏分段每递增10%体积,馏出体积在10%—40%、50%—90%和90%—100%时的硫含量则平均增加0.91—1.33mg、7.51—12.89mg和68.18—170.47mg;馏出体积从10%增大到90%时各窄馏分硫含量数值渐次增大且数值变化较平缓;馏出体积为90%—100%时硫含量数值有明显突跃变化,该窄馏分段中硫含量占整个馏分油中硫含量的20.76%—27.95%;硫含量最大值在1.2%(V/V)残留量中。The distribution of sulfer in fractions of export gasoline was studied by volume-cutting method.The every increased by 10% of the volume between the fractions leads to increase 0.91—1.33mg,7.51—12.89mg and 68.18—170.47mg in the average content of sulfur for 10%—40%,50%—90% and 90%—100%＇s distilled volume,respectively.The content of sulfur in each fraction growed gradually when distilled volume was from 10% to 90%,but rapidly increased for 20.76%—27.95% of total sulfur in the samples in the distilled volume range from 90% to 100%.The maximum content of the sulfur occurred in 1.2%＇s residual.
