摘要
建立了气相色谱分析裂解汽油加氢原料中C5总含量的分析方法。方法的精密度分析结果表明,方法的实验室内相对标准偏差小于2%,实验室间相对标准偏差小于3%,而且方法的精密度与样品水平呈明显的线性关系。本方法具有很好的重复性和再现性,可以为石油炼化企业的裂解汽油加氢原料中C5总含量的测定提供统一的检测依据。
Method for total content determination of C5 in feedstock for the hydrogenation of pyrolysis gasoline by capillary gas chromatography was build.The results of precision analysis showed that,the relative standard devi- ation within laboratory was less than 2%, the relative standard deviation between laboratorys was less than 3%,the precision and sample level had a linear relationship. This method had a good repeatability and reproducibility, it provided a unified basis for petrochemical plants to determine the total content of C5 in feedstock for the hydro- genation of pyrolysis gasoline.
