Decarbonylative Dehydration of Biomass-derived γ-Valerolactone to Form 1,3-Butadiene Catalyzed by H-ZSM-5

We report a method for the direct conversion of γ-valerolactone (GVL) to 1,3-butadiene (BD). The reaction was catalyzed by H-ZSM-5 with a SiO2/Al2O3 molar ratio of 50. BD could be efficiently produced at 400 °C under an ambient pressure: a BD selectivity of 80.9% with a GVL conversion of 96.7% was achieved in an H2 flow of 90 cm3 h−1. The direct formation of BD from GVL proceeded via decarbonylation followed by dehydration to produce CO and H2O.
