Levulinic acid (LA) is a substance, which can be obtained from cellulosic biomass via acid hydrolysis. Hydrogenation of LA to gamma-valerolactone (GVL) is one of the most promising reactions in the field of biomass valorization to fine chemicals and liquid transportation fuels. Potentially, GVL obtained from lignocellulosic biomass is a versatile intermediate for the production of fuel additives and chemicals. Due to the high demand for GVL, its efficient production is currently a topic of intensive research. This work is devoted to the synthesis and study of catalytic properties of Ru-containing system based on ZSM-5 in selective hydrogenation of levulinic acid (LA) to gamma-valerolactone (GVL), which is a semi-product for obtaining of liquid fuel components. Synthesized catalyst RuO2/ZSM-5 was shown to not need any pretreatment and activation procedure and it is promising for LA hydrogenation: nearly100% yield of GVL was found in aqueous medium under relatively mild conditions (100oC, 10-20 bar H2 partial pressure) for 2 h of reaction time.
