Efficient production of γ-valerolactone (GVL) from biomass-derived furfural has received increasing attention among many researchers because it is a sustainable platform molecule for the production of various fuels and chemicals, such as polymer precursors, diesel and jet fuel. Recently, it has been shown that GVL can be directly synthesized from furfural through sequential Meerwein-Ponndorf-Verley (MPV) and hydrolysis reactions using zeolites with Lewis and Brønsted acid sites (e.g., Zr-Al-Beta) as catalysts and alcohols (e.g., 2-propanol) as hydrogen donors. However, the inherent low Brønsted acidity of Zr-Al-Beta lowers the selectivity toward GVL. In this work, we have employed heteropolyacids (HPAs) as the source of Brønsted acid sites on Zr-Beta zeolite and applied to the one-pot conversion of furfural to GVL. The effects of catalyst preparation conditions and the types of HPA on acid site distribution of HPA/Zr-Beta and the GVL selectivity were investigated. |
