The Fischer-Tropsch (FT) process involves a series of catalysed reactions of carbon monoxide and hydrogen, originating from coal, natural gas or biomass, leading to a variety of synthetic chemicals and fuels. The benefits of comprehensive two-dimensional gas chromatography (GC×GC) compared to one-dimensional GC (1D-GC) for the detailed investigation of the oil products of low and high temperature FT processes are presented. GC×GC provides more accurate quantitative data to construct Anderson-Schultz-Flory (ASF) selectivity models that correlate the FT product distribution with reaction variables. On the other hand, the high peak capacity and sensitivity of GC×GC allow the detailed study of components present at trace level. Analyses of the aromatic and oxygenated fractions of a high temperature FT (HT-FT) process are presented. GC×GC data have been used to optimise or tune the HT-FT process by using a lab-scale micro-FT-reactor.
费托（FT）工艺涉及一系列一氧化碳和氢气的催化反应，这些反应的原料来自煤、天然气或生物质，可生成各种合成化学品和燃料。本文介绍了与一维气相色谱（1D-GC）相比，全面二维气相色谱（GC×GC）在详细研究低温和高温 FT 工艺的油产品方面的优势。GC×GC 提供更准确的定量数据，以构建安德森-舒尔茨-弗洛里（ASF）选择性模型，将 FT 产物分布与反应变量相关联。另一方面，GC×GC 的高峰容量和灵敏度允许对痕量存在的成分进行详细研究。本文介绍了高温 FT（HT-FT）工艺中芳烃和含氧化合物馏分的分析。通过使用实验室规模的微 FT 反应器，GC×GC 数据已用于优化或调整 HT-FT 工艺。
