It is imperative to develop more efficient processes for conversion of biomass to liquid fuels, such that the cost of these fuels would be competitive with the cost of fuels derived from petroleum. We report a catalytic approach for the conversion of carbohydrates to specific classes of hydrocarbons for use as liquid transportation fuels, based on the integration of several flow reactors operated in a cascade mode, where the effluent from the one reactor is simply fed to the next reactor. This approach can be tuned for production of branched hydrocarbons and aromatic compounds in gasoline, or longer-chain, less highly branched hydrocarbons in diesel and jet fuels. The liquid organic effluent from the first flow reactor contains monofunctional compounds, such as alcohols, ketones, carboxylic acids, and heterocycles, that can also be used to provide reactive intermediates for fine chemicals and polymers markets.
开发更高效的将生物质转化为液体燃料的工艺势在必行,这样这些燃料的成本才能与源自石油的燃料成本具有竞争力。我们报告了一种将碳水化合物转化为特定类别的烃以用作液体运输燃料的催化方法,该方法基于几个以级联模式运行的流动反应器的集成,其中一个反应器的流出物直接输送到下一个反应器。这种方法可进行调整,以生产汽油中的支链烃和芳香族化合物,或柴油和喷气燃料中链更长、支化程度较低的烃。第一个流动反应器的液态有机流出物含有单官能化合物,如醇、酮、羧酸和杂环化合物,这些化合物也可用于为精细化学品和聚合物市场提供反应中间体。
