Biomass represents an abundant and relatively low cost carbon resource that can be utilized to produce platform chemicals such as levulinic acid. This study focused on the effect of SO42-/TiO2-Al2O3-SnO2 solid acid catalyst on the catalytic performance in levulinic acid production from biomass-derived carbohydrates glucose. The SO42-/TiO2-Al2O3-SnO2 solid acid catalyst showed a high catalytic activity for the selective conversion of glucose to levulinic acid. Experimental results showed that SO42-/TiO2-Al2O3-SnO2 solid acid had markedly catalytic effects on the conversion of glucose to levulinic acid. With SO42-/TiO2-Al2O3-SnO2 solid acid as the catalyst, an optimized ethyl levulinic acid was obtained at 180 degrees C for 2 h with glucose dosage of 2 wt% and 3 g SO42-/TiO2-Al2O3-SnO2 solid acid catalys and the levulinic acid yield was 74.05%.
