实现低碳社会迫切需要化学合成中的可持续技术和高效工艺设计。在这里,通过生物质衍生的负碳路线设计了一种生产芳烃的可持续方法。使用工业含水含氧化合物混合物作为原料,实现了高达50%的目标芳烃产率。这种高性能归因于Zn改性的ZSM-5沸石,其被证明引入涉及刘易斯酸中心和布朗斯台德酸中心的协同催化,并且对于有效地芳构化这些含氧化合物是必不可少的。这种方法为将生物质衍生的复杂混合物转化为有价值的化学品以实现碳中和目标提供了一条有前途的途径。
Sustainable technologies and efficient process design in chemical synthesis are in great demand for achieving a low-carbon society. Here, a sustainable approach for producing aromatics is designed via a biomass-derived carbon-negative route. A target aromatic yield of up to 50% was achieved using an industrial aqueous oxygenate mixture as the feedstocks. Such high performance is ascribed to the Zn modified ZSM-5 zeolites, which were proved to introduce synergistic catalysis involving Lewis acid sites and Brönsted acid sites, and were essential to aromatize these oxygenates efficiently. This approach provides a promising route for converting biomass-derived complex mixtures to valuable chemicals toward the carbon-neutral goal.
