Innovative conversion of biodiesel-glycerol to butanol as a biofuel

化石燃料的枯竭使得寻找替代能源或可再生能源变得更加迫切。虽然乙醇、氢气和生物柴油等几种可再生能源已经显示出其应用潜力，但丁醇在这方面开始受到更多的关注。与作为普通汽油添加剂的甲醇或乙醇相比，丁醇含有更多的碳含量，具有更高的能量含量，操作起来更安全，腐蚀性更小。与汽油相比，丁醇的能量含量和燃油效率大致相同，但更环保。在十六烷值CN25较高的情况下，丁醇可以与石油柴油或生物柴油混合，以降低凝胶温度和粘度。目前，丁醇主要通过石化加工生产。为了应对最近油价飙升，如果找到更便宜的原料，生物转化产量和产量增加，生物路线可以变得更具竞争力。

The depletion of fossil fuels makes the search of alternative or renewable energy sources more imperative. While several renewable energy forms, such as ethanol, hydrogen, and biodiesel, have demonstrated their applicative potential, butanol starts to gain more attention in this aspect. Compared to methanol or ethanol as a common gasoline supplement, butanol contains more carbon content, has a higher energy content, and is safer to handle and less corrosive. Compared to gasoline, butanol has approximately the same energy content and fuel efficiency but is more environmentally friendly. With a high cetane number of CN25, butanol can be blended with petrodiesel or biodiesel to reduce the gel temperature point and the viscosity. Currently, butanol is produced primarily via petrochemical processing. In response to the recently soaring oil price, the biological route can become more competitive if cheaper feedstock is identified and biotransformation yield and
