    • Methods are disclosed for forming heptan-4-one, and, optionally, heptan-4-ol, from fermentable sugars. The sugars are fermented using a bacteria or yeast that predominantly forms butyric acid. The butyric acid is subjected to catalytic ketonization conditions to form heptan-4-one, with concomitant loss of water and carbon dioxide. The heptan-4-one can be subjected to catalytic hydrogenation to form heptan-4-ol, an either of these can be included in gasoline compositions. In one aspect, the fermentable sugars are derived from lignocellulosic materials such as wood products, switchgrass, or agricultural wastes, which are delignified to form lignin, cellulose and hemicellulose. The cellulose and hemicellulose can be depolymerized to form glycose and xylose, either or both of which can be fermented by the bacteria. Thus, the methods described herein can convert biomass to a fuel composition or fuel additive, which can be used in a conventional gasoline engine, unlike traditional fuels such as ethanol or biodiesel.
    • 公开了用于从可发酵糖形成庚-4-酮和任选的庚-4-醇的方法。 使用主要形成丁酸的细菌或酵母发酵糖。 将丁酸经受催化酮化条件以形成庚-4-酮,伴随着水和二氧化碳的损失。 庚-4-酮可以进行催化氢化以形成庚-4-醇,其中任何一种都可以包含在汽油组合物中。 一方面,可发酵糖衍生自木质纤维素材料,如木制品,柳枝稷或农业废弃物,木质纤维素材料被脱木质素形成木质素,纤维素和半纤维素。 纤维素和半纤维素可以解聚形成糖和木糖,其中一种或两种都可以被细菌发酵。 因此,本文所述的方法可将生物质转化成可用于常规汽油发动机中的燃料组合物或燃料添加剂,其不同于传统燃料如乙醇或生物柴油。
