摘要:

以生物质为原料制备燃料化学品对减少化石能源的依赖和构建绿色能源结构具有重要意义。近年来生物质平台化合物糠醛一锅多步转化为乙酰丙酸及乙酰丙酸酯、γ-戊内酯和2-甲基呋喃等高附加值燃料化学品的研究引起了关注。本文综述了近6年来糠醛一锅转化为乙酰丙酸及乙酰丙酸酯、γ-戊内酯和2-甲基呋喃的双功能催化剂研究进展,总结了各反应多步转化的反应路径及可能的机理,归纳了高效催化剂的类型及所需要各步所需的活性中心,为设计制备糠醛转化为高价值燃料化合物的高效双功能催化剂提供了思路,为糠醛的进一步开发和更好利用提供有价值的参考。

Abstract:

The preparation of fuel chemicals using biomass as raw materials is of great significance in reducing dependence on fossil fuels and building a green energy structure. In recent years, research on the one-pot multi-step conversion of the biomass platform compound furfural into high value-added fuel chemicals such as levulinic acid and levulinate esters, γ-valerolactone and 2-methylfuran has attracted attention. In this paper, the research progress in bifunctional catalysts for one pot conversion of furfural to levulinic acid, levulinic acid ester, γ-valerolactone and 2-methylfuranin in recent six years is reviewed. The reaction paths and possible mechanisms of the multi-step conversion reactions were summarized, and the types of high-efficiency catalysts and the required active centers for each step were also summarized. It provides a new idea for the design and preparation of high efficient bifunctional catalysts for the conversion of furfural into high-value fuel compounds , and provides valuable reference for further development and better utilization of furfural.
