In the late 1850s, Charles Friedel’s dry distillation of calcium acetate gave the world a novel route to the commercial production of acetone, a process that would later be referred to as decarboxylative dehydration (ketonization). While the subsequent development of the petrochemical industry made this route to acetone uncompetitive, today there is considerable interest in ketonization as means for converting biomass-derived fatty acids to produce longer-chained ketones, which could serve as precursors to fuels and lubricants. However, the lack of strategies beyond direct hydrogenation of the ketones into hydrocarbons has limited the practical application of ketonization for producing biofuels. We describe here an integrated strategy for converting a range of biomass-derived carboxylic acids, sourced through fermentation of sugars, hydrolysis of lipids, or biomass pyrolysis, to compounds that are fully compatible with the existing energy infrastructure and require minimal hydrogen input.

集成的催化序列，可将生物衍生的羧酸催化降解为燃料，润滑剂和化学原料

在1850年代后期，查尔斯·弗里德尔（Charles Friedel）对醋酸钙进行干馏，为全世界提供了一条商业化生产丙酮的新途径，这一过程后来被称为脱羧脱水（酮化）。尽管石化工业的后续发展使这种通往丙酮的途径失去了竞争力，但如今，人们对酮化有相当大的兴趣，酮化是一种将生物质衍生的脂肪酸转化为更长链的酮的方法，可以用作燃料和润滑剂的前体。然而，除了将酮直接氢化成烃外，缺乏策略限制了酮化在生产生物燃料中的实际应用。我们在这里描述了一种综合策略，用于转化通过糖发酵获得的一系列生物质衍生的羧酸，
