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 volume fraction method was used to analyze the distribution of sulfur content in gasoline in the distillate. The results showed that for every increment of 10% by volume, the sulfur content of distillate decreased from 0.91 to 1.33 mg, 7.51 to 12.89 mg and 10% to 40%, 50% to 90% and 90% to 100% 68.18-170.47mg. When the volume of distillate increases from 10% to 90%, the content of sulfur in each narrow fraction gradually increases and the change of the value is gentle. When the volume of distillate is 90% -100%, the value of sulfur content changes obviously , The content of sulfur in the narrow distillation section is 20.76% -27.95% of the total sulfur content in the whole distillate, and the maximum sulfur content is in the residual amount of 1.2% (V / V).
