Liquid Transportation Fuels from Sugar-Derived 2-Hexanol. Effect of Cu Content in Cu-Mg-Al Mixed Oxides.Lignocellulose can be obtained from non-edible sources and therefore, offers an attractive option as an inexpensive feedstock for the efficient second-Generation liquid fuel production in a biorefinery. Subsequent primary sugar conversion may result in the formation of a hydrophobic mixture of the so called ?platform molecules?, i.e., C5-C6 alcohols, ketones, acid and furan-derivatives. Further conversion of these molecules must include an oxygen removal step to decrease the O/C atomic ratio in the product pool. Liquid transportation fuels (LTF) consist of nonoxygenated hydrocarbons in the range of C9-C16 for jet fuel and C12-C20 for diesel. Here, we investigate the synthesis of LTF from 2-hexanol, a model molecule of the primary conversion of sugars. Main products are C9-C24 compounds formed by tandem dehydrogenation/C-C coupling/dehydration/ hydrogenation reactions.Significance:High yields of C9-C24 compounds (87%) with jet fuel applications are obtained on Cu-Mg-Al oxides with moderate basic properties and dispersed Cu0 atoms.
