化石燃料的燃烧伴随着许多令人担忧的问题，例如化石燃料耗尽、价格上涨和温室气体排放。因此，对替代性可再生生物燃料的需求增加，以取代不可再生的化石燃料。可持续地利用非食用原料和废物生产生物燃料是减少对化石燃料的依赖和减轻环境污染的一个潜在办法。在连续式反应器中，研究了不同碳氮比（C/N）对麻疯树籽仁、芒果皮厌氧共消化过程中甲烷产率的影响。J.在厌氧分批消化过程中也评价了curcasfruit。与芒果皮、籽仁、芒果皮/籽仁（2：1 w/w）和芒果皮/籽仁（1：1 w/w）的甲烷产率相比，共消化的芒果皮和籽仁（基于挥发性固体的1：4重量比）的甲烷产率分别高61%、50%、36%和25%。芒果皮和果核以1：4、1：1和2：1比例共消化的甲烷产率分别为理论产率的52%、39%和32%，说明了用适量的共基质调节C/N比的重要性。经预处理的种皮比种仁、种皮（未经预处理）、脱油种仁与种皮（1.7：1）（经预处理）、种皮（未经预处理）和种皮（未经预处理）的产气量分别高7%、22%、34%、50%和74%。此外，果皮和种皮的预处理导致22%和47%的沼气产量比未预处理的同行。该研究揭示了提高普通种子油生产和农业废物甲烷产量的关键基质选择和预处理方法。
The combustion of fossil fuels is accompanied with a number of alarming problems such as fossil fuel depletion, increase in their prices, and emission of greenhouse gases. Thus, the need for the alternative renewable biofuels was increased to replace non-renewable fossil fuels. The sustainable use of non-edible feedstocks and waste for production of biofuels is a potential approach for reducing dependency on fossil fuels and mitigating environmental pollution. In the current study, the effects of carbon to nitrogen (C/N) ratios on methane yield during anaerobic co-digestion ofJatropha curcasde-oiled seed kernel and mango peels were evaluated in continuous reactors. The biogas potential and effects of acid pretreatment onJ. curcasfruit were also evaluated during anaerobic batch digestion. The methane yield of co-digested mango peels and seed kernel (1:4 weight ratio based on volatile solids) was 61%, 50%, 36%, and 25% higher compared with the methane yields of mango peels, seed kernel, mango peels/seed kernel (2:1 w/w), and mango peels/seed kernel (1:1 w/w), respectively. The methane yields of the co-digestion of mango peels and seed kernel at 1:4, 1:1, and 2:1 ratios were 52%, 39%, and 32% of the theoretical yields, respectively, illustrating the importance of adjusting C/N ratio with the right amounts of co-substrate. The biogas yield of pretreated fruit coat was 7%, 22%, 34%, 50%, and 74% higher than that of the seed kernel, fruit coat (non-pretreated), de-oiled kernel plus seed coat (pretreated) (1.7:1, by weight), seed coat (pretreated), and seed coat (non-pretreated), respectively. Additionally, pretreatment of fruit coat and seed coat resulted in 22% and 47% higher biogas yields compared with their non-pretreated counterparts. This study revealed key substrate selection and pretreatment methods for increasing methane production from common seed oil production and agricultural wastes.Graphical abstract
