Abstract

The characterization of bio-aviation fuel composition is paramount for assessing biomass conversion processes and its suitability to meet international standards. Compared with one-dimensional gas chromatography mass spectrometry (1DGC-MS), comprehensive two-dimensional gas chromatography with mass spectrometry (GC × GC-MS) emerges as a promising analytical approach for bio-aviation fuel, offering enhanced separation, resolution, selectivity, and sensitivity. This study addresses the qualitative and quantitative analysis methods for both bulk components and trace fatty acid methyl ester (FAME) in bio-aviation fuel obtained by hydrogenation at 400 °C with Ni-Mo/γ-Al₂O₃&Meso-SAPO-11 as catalyst using GC × GC-MS. In bulk composition analysis, C₁₂ concentration was highest at 25.597%. Based on GC × GC-MS analysis platform, the quality control method of FAME in bio-aviation fuel was established. At the split ratio of 10:1, limits of detections of six FAMEs were 0.011–0.027 mg·kg⁻¹, and limits of quantifications were 0.036–0.090 mg·kg⁻¹, and the GC × GC-MS research platform had the ability to detect FAME from 2 to 5 mg·kg⁻¹. The results showed that this bioaviation fuel did not contain FAME.

利用综合二维气相色谱质谱法深入分析从废弃食用油中提取的生物航空燃料的多组分成分

生物航空燃料成分的表征对于评估生物质转化过程及其是否符合国际标准至关重要。与一维气相色谱-质谱法（1DGC-MS）相比，综合二维气相色谱-质谱法（GC × GC-MS）具有更高的分离度、分辨率、选择性和灵敏度，是一种很有前途的生物航空燃料分析方法。本研究以 Ni-Mo/γ-Al2O3&Meso-SAPO-11 为催化剂，利用 GC × GC-MS 对 400 °C 加氢得到的生物航空燃料中的大量成分和痕量脂肪酸甲酯 (FAME) 进行定性和定量分析。在主体成分分析中，C12 的浓度最高，为 25.597%。基于 GC × GC-MS 分析平台，建立了生物航空燃料中 FAME 的质量控制方法。在分流比为 10:1 时，6 种 FAME 的检出限为 0.011-0.027 mg-kg-1，定量限为 0.036-0.090 mg-kg-1，GC×GC-MS 研究平台具有检测 2 至 5 mg-kg-1 FAME 的能力。结果表明，这种生物航化燃料不含 FAME。
