The determination of ppm to ppb levels of sulfur, oxygen-containing, and certain reactive hydrocarbons in bulk hydrocarbon feedstocks is important in the petroleum and petrochemical industry to minimize catalytic deactivation and improve product quality. Gas chromatography, coupled with selective or ultratrace universal detection (or both), is ideal in most cases for such analysis. However, to enhance
在石油和石化工业中,测定散装烃原料中的硫,含氧和某些反应性烃的ppm到ppb的水平,对于最小化催化失活和提高产品质量至关重要。在大多数情况下,气相色谱与选择性或超痕量通用检测(或两者)结合是理想的分析方法。但是,为了提高痕量水平的选择性和定量分析,需要优化的固定相。这些相通常是吸附剂类型。本文总结了几种最先进的相用于分析痕量关键碳氢化合物,硫和氧化成分的性能。
