Scope

This standard specifies the test method for determining the hydrocarbon composition and benzene content in light petroleum fractions and products using multidimensional gas chromatography technology. This standard applies to the determination of hydrocarbon composition and benzene content in light petroleum fractions or products with a final distillation point not exceeding 215 °C, such as gasoline blending components, solvent oils, and gasoline products. The measurement concentration range is: olefin volume fraction (or mass fraction) from 0.5% to 70%; aromatic hydrocarbon volume fraction (or mass fraction) from 1% to 80%; and benzene volume fraction (or mass fraction) from 0.2% to 10%. The method is also applicable to gasoline products obtained from unconventional crude oils such as shale or oil sands, or hydrocarbon fuels synthesized from non-petroleum mineral fuels like Fischer-Tropsch synthesis oil. Samples exceeding the concentration range can also be measured, but no precision data are provided. For automotive gasoline, to improve the performance of gasoline products or for other purposes, it often contains ether or alcohol oxidized compounds. In this case, the ether compounds in the sample will peak together with the olefin components, and the alcohol compounds will peak together with the C7+ aromatic components. For gasoline samples containing oxidized compounds, the type and content of the oxidized compounds should be determined using relevant test methods (such as SH/T 0663), and the hydrocarbon composition results should be corrected as necessary according to the steps in Appendix A before applying this standard. This standard is not applicable to the determination of the monomer component content in each hydrocarbon group except benzene.
