%X The data about the decomposition kinetics of 5-hydromethylfurfural(5-HMF) without any catalyst and catalyzed by solid acid SO42-/ZrO2-TiO2 and SO42-/ZrO2 at temperatures from 423.15 K to 463.15 K was obtained by conducting decomposition reaction in a small high-pressure batch reactor respectively. The results showed that the effects of reaction time, reaction temperature and solid acids on the 5-HMF conversion and the levulinic acid(LA) yield were significant. After fitting experimental data with the first-order kinetics equation, the evaluated apparent activation energy of 5-HMF decomposition was 106.4 kJ/mol without any catalyst, 73.42 kJ/mol catalyzed with solid acid SO42-/ZrO2-TiO2 and 77.04 kJ/mol with solid acid SO42-/ZrO2, respectively. On the other hand, the solid acid catalysts are easy to be recycled and reusable.
