丙酮-丁醇-乙醇发酵工艺广泛应用于生物丁醇的生产，而该工艺的初步产物是丙酮、丁醇和乙醇的三元混合物（ABE），直接使用ABE而无需纯化步骤将大大降低成本。在这项研究中，为了了解ABE燃料中的酮-醇官能团如何影响燃烧中间产物池和潜在的化学交联效应，详细研究了ABE燃料层流预混火焰的化学结构，采用同步辐射真空紫外（SVUV）分子束质谱技术对丙酮-丁醇（AB）和丙酮-乙醇（AE）混合物进行了系统研究。作为电离源。约40种物种被明确确定和量化。开发了一个动力学模型，并对单个燃料（丙酮，乙醇和丁醇），二元和三元混合物的火焰进行了验证。苯的前体物，不饱和烃，和有毒的醛的浓度低于在ABE火焰比丁醇火焰。模型分析方面的生产率（ROP）表明，这些差异归因于体积效应，而不是强烈的动力学相互作用的反应途径的个别燃料成分。
Acetone–butanol–ethanol fermentation processes are widely used for the bio-butanol production, while the preliminary product of this process is a ternary mixture of acetone, butanol and ethanol (ABE), the direct use of which without purification steps will substantially reduce the cost. In this study, in order to understand how the ketone–alcohol functionalities in ABE fuel affect the combustion intermediate species pool and the potential chemical cross-linking effects, the detailed chemical structures of laminar premixed flames fueled by ABE, an acetone–butanol (AB) mixture and an acetone–ethanol (AE) mixture were systematically investigated using molecular beam mass spectrometry with the synchrotron vacuum ultraviolet (SVUV) being the ionization source. About 40 species were unambiguously identified and quantified. A kinetic model was developed and validated against flames of individual fuels (acetone, ethanol and butanol), binary and ternary mixtures. The concentrations of benzene precursors, unsaturated hydrocarbons, and the toxic aldehydes were lower in the ABE flame than those in the butanol flame. Modeling analysis in respect of rate of production (ROP) indicated that these differences were attributed to the volume effects, instead of strong kinetic interactions among the reaction pathways of individual fuel components.
