Furfural Valorization to γ‑Valerolactone over Zr/Sn Zeolite-Supported Catalysts in a Liquid-Phase Continuous Flow Reactor.

A maximum in the trend was obtained with the Sn:Zr/HY catalyst (1:1), which has 447.01 μmol g –1 of Lewis acid sites and was the most promising material with a GVL yield of 45%, As the number of Lewis acid sites continued to increase, a decreasing trend was observed, in fact that the catalyst (1:9) showed a GVL selectivity of 35% with 605.5 μmol g –1 Lewis acid sites and the catalyst (9:1) had a GVL selectivity of 30% with 733.3 μmol g –1 Lewis acid sites.
