The oxidation of furfural has been studied experimentally in a jet-stirred reactor (JSR) under fuel-lean (Φ = 0.4) and fuel-rich conditions (Φ = 2.0) in the temperature range of 650–950 K; in addition, laminar burning velocity data have been measured at T = 473 K and p = 1 bar within a wide fuel-air range. From the JSR experiments, 13 species profiles have been identified and quantified by GC–MS and GC. A detailed kinetic reaction model involving 382 species and 2262 reactions was developed by exploiting the experimental data base provided within the present work as well as experimental data reported in literature. The rate coefficients of reactions of H abstraction, H addition as well as of decomposition of furfural were calculated by quantum chemical methods at CBS-QB3 level. A general agreement was achieved when simulating the experimental data. Rate of production analysis as well as sensitivity analysis were performed to get a deeper insight into the combustion of furfural, e.g. for the jet-stirred reactor data at around 50% fuel conversion, as well as sensitivity analysis of laminar flame speeds conducted for a fuel-air ratio Φ = 0.9, 1.2, and 1.6. According to the analysis, the main consumption pathways of furfural oxidation were identified as H abstraction reactions of the R-CHO (aldehyde) group by H, OH, O, and HO₂ to produce a furfural radical (furfural-6). At pyrolysis condition, the dominant pathways within the furfural decay were found to occur via ring opening by splitting the CO bond followed by isomerization to form α-pyrone (C₅H₄O₂). Even more, the measured laminar flame speed data are well reproduced by the reaction model developed within the present work. The experimental data base as well as the developed reaction model will assist and contribute to a more detailed understanding of the combustion behavior of furfural and of furan derivatives as well.

已经在650-950 K温度范围内的贫燃料（Φ= 0.4）和富燃料条件（Φ= 2.0）的喷射搅拌反应器（JSR）中对糠醛的氧化进行了实验研究。另外，在T  = 473 K和p下测量了层流燃烧速度数据。 = 1 bar在较宽的燃油空气范围内。通过JSR实验，通过GC-MS和GC鉴定并定量了13种物种。通过利用本工作中提供的实验数据库以及文献中报道的实验数据，开发了涉及382种和2262种反应的详细动力学反应模型。通过量子化学方法在CBS-QB3水平上计算了H的提取，H的添加以及糠醛的分解反应的速率系数。模拟实验数据时，已达成总体共识。进行了生产率分析和敏感性分析，以更深入地了解糠醛的燃烧，例如，对于约50％燃料转化率的喷射搅拌反应器数据，以及对空气燃料比Φ= 0.9、1.2和1.6进行的层流火焰速度的敏感性分析。根据分析，糠醛氧化的主要消耗途径被确定为R-CHO（醛）基通过H，OH，O和HO的H抽象反应₂产生糠醛自由基（furfural-6）。在热解条件下，发现糠醛衰变中的主要途径是通过开环发生的，该过程是通过裂解C O键，然后异构化形成α-吡喃酮（C ₅ H ₄ O ₂）。更重要的是，在当前工作中开发的反应模型很好地再现了测得的层流火焰速度数据。实验数据库以及已开发的反应模型将有助于并有助于更深入地了解糠醛和呋喃衍生物的燃烧行为。
