乙酰丙酸加氢制备γ-戊内酯催化剂研究进展OACSTPCD

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,and γ-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.
