Research progress of catalyst for levulinic acid hydrogenation toγ‑valerolactone

催化转化碳中性且可再生的生物质制备液体燃料和精细化学品是实现双碳目标的主要途径之一,γ-戊内酯(GVL)可作为绿色溶剂并可用于合成高品位航空燃料。乙酰丙酸(LA)是重要的生物质平台化学品,经催化加氢可制备高附加值产品GVL。首先简要介绍了生物质组成,然后从所采用的均相催化剂、多相催化剂(Ru、Pd、Ni、Cu和双金属)等分类角度重点综述了LA加氢制备GVL的研究进展,详细讨论了催化剂结构性质、反应性能、稳定性、构效关系和反应机理。最后,对LA加氢制备GVL面临的挑战进行了分析,对未来的研究方向和发展趋势作了进一步展望,可为设计大规模商业应用的高活性耐酸性Ru基催化剂提供参考。

Catalytic conversion of carbon-neutral and renewable biomass into liquid fuel and fine chemicals is one of main solutions to achieve carbon peaking and carbon neutrality goals,andγ-valerolactone(GVL)can be used as a green solvent and can be synthesized into high-grade aviation fuel.Levulinic acid(LA),as an important biomass-derived platform chemical,can be catalytically hydrogenated into highly value-added GVL.Biomass composition was briefly introduced first,and then the research progress of LA hydrogenation to GVL was fully reviewed based on the perspective of homogeneous and heterogeneous catalysts(Ru,Pd,Ni,Cu and bimetal).The catalyst structural properties,reaction performance,stability,structure-performance correlation and reaction mechanism were discussed in detail.Finally,the major challenges were analysized,future prospects and development trend for LA hydrogenation to GVL were further prospected,which can provide a basis for designing high-activity and acid-resisting Ru-based catalysts with large-scale commercial applications.
