Abstract:

As a important biomass platform compound, γ-valerolactone(GVL) could be used as green solvent, polymer precursor, fuel, and fuel additive, etc. Therefore, catalytic conversion of biomass to GVL was one of the important ways to utilize resource-based bio material and alleviate the resource and energy crisis. Furfural underwent Meerwein-Ponndorf-Verley(MPV) transfer hydrogenation reaction to prepare GVL in one pot had the advantages of simple operation, economy, environmental protection, safety and reliability. It was a route with great industrialization potential in the field of GVL synthesis research, therefore, it had received extensive attention from academia and industry. This paper described the catalytic activity centers of Brønsted acid(B acid) and Lewis acid(L acid) required for each step of the conversion of furfural to GVL. The efficient solid catalysts for the preparation of GVL by the one-pot method from furfural were summarized in terms of catalyst construction methods and the structure of the carrier. Molecular sieves with hydrothermal stability and good mass transfer effect(e.g. beta molecular sieve, ZSM-5 molecular sieve, etc.) were found to be the commonly used carriers in this reaction. In addition, modification by molecular sieves with de-Al, or introducing active centers such as Zr and Hf compounds with L acid sites, and phosphotungstic acid with B acid sites are common means to construct efficient bifunctional catalysts for the this reaction. The causes of catalyst deactivation and regeneration methods were also summarized in this paper, and the effects of catalytic reaction conditions such as solvent and temperature on the reaction activity were analyzed. At the same time, some suggestions were provided for the design of new and efficient catalysts for this reaction.
