| 摘 要： | 采用气相色谱-原子发射光谱联用(GC-AED)技术，建立了催化裂化汽油中各种硫化物类型分布的分析方法。考察了色谱条件对催化汽油中各种硫化物分离的影响，定性了催化汽油中的60余种硫化物，首次计算了程序升温条件下汽油馏分中各种硫化物的保留指数，为不同实验室的定性比较提供了依据。该方法可应用于不同来源汽油中各种硫化物类型分布的研究。

Determination and Distribution of Sulfur Compounds in Gasoline by Gas Chromatography-Atomic Emission Detector |

| Abstract: | The method for separation and determination of sulfur compounds in fluid catalytic cracking gasoline by gas chromatography-atomic emission detector(GC-AED) was established. More than sixty sulfur compounds were quantified. The effects of speed of carrier gas, oven temperature on resolution and column effects were discussed. Retention indices of different sulfur compound in temperature programmed condition were calculated. External calibration curve was applied to the area responses of each sulfur components in the sulfur chromatogram, and the concentration of each was calculated. The contents of each sulfur compound in gasoline and desulfured gasoline were determined. |
