Levulinic acid is a valuable platform chemical which could be used as raw material to synthesis various chemicals and fuels. In this work, citric acid modified HZSM-5 and aluminum ion modified HZSM-5 were prepared and used in the production of levulinic acid from glucose. The modified HZSM-5 was characterized by XRD, SEM, FTIR, BET, TG and pyridine FTIR. The Brønsted acid sites density of citric acid modified HZSM-5 was higher than aluminum ion modified HZSM-5. More importantly, the kinetics of levulinic acid production catalyzed by citric acid modified HZSM-5 and aluminum ion modified HZSM-5 were investigated, respectively. The Saeman model was applied to predict the concentration of levulinic acid, and the values calculated by the model agreed well with the experimental data. The rate of production of levulinic acid with citric acid modified HZSM-5 was higher than that of aluminum ion modified HZSM-5. The model supplied a profound understanding in the conversion of glucose into levulinic acid with modified H-ZSM-5 zeolite.
