Instead of anaerobic digestion of biodegradable wastes for producing methane, this work introduced the transformation of acidogenesis products (VFAs) into fatty acid methyl esters (FAMEs) to validate the feasible production of short-chained fatty alcohols via hydrogenation of FAMEs. In particular, among VFAs, this work mainly described the mechanistic explanations for transforming butyric acid into butyric acid methyl ester as a case study. Unlike the conventional esterification process (conversion efficiency of ∼94%), the newly introduced esterification under the presence of porous materials via the thermo-chemical process reached up to ∼99.5%. Furthermore, the newly introduced esterification via the thermo-chemical pathway in this work showed extremely high tolerance of impurities: the conversion efficiency under the presence of impurities reached up to ∼99±0.3%; thus, the inhibition behaviors attributed from the impurities used for the experimental work were negligible.
本工作介绍了将产酸相产物（VFAs）转化为脂肪酸甲酯（FAMEs），而不是对可生物降解废物进行厌氧消化以生产甲烷，以验证通过 FAMEs 的加氢反应可行地生产短链脂肪醇。特别是在 VFAs 中，本工作主要描述了将丁酸转化为丁酸甲酯的机理解释作为案例研究。与传统的酯化过程（转化率约为 94%）不同，在热化学过程中通过多孔材料引入的新酯化反应达到了约 99.5%。此外，本工作中新引入的热化学途径酯化反应对杂质具有极高的耐受性：在杂质存在下的转化率达到了约 99±0.3%；因此，实验工作中所用杂质的抑制行为可以忽略不计。
