Abstract

Abstract

Zn/ZSM-5 zeolite catalysts with different Zn contents were prepared by impregnating method. The influence of reaction temperature, reaction time, catalyst dosage, and the acidic properties of catalysts on the conversion of γ-valerolactone to aromatic compounds was investigated.The results show that the introduction of Zn into H-ZSM-5 channel could effective modify the components of liquid product and influence the yields of gas, liquid, and solid as compared to H-ZSM-5 catalyst and non-catalytic conversion of γ-valerolactone. Zn/ZSM-5 catalyst affords the higher contents of aromatic compound compared to H-ZSM-5 and silica catalysts in the liquid product under identical reaction conditions. Therefore, Zn species of Zn/ZSM-5 can not only effectively improve the conversion of γ-valerolactone, but also enhance the formation of aromatic compounds, suggesting that Zn species play a very key role in the formation of these aromatic compounds.
