- Abstract:
- Solid acid catalyst SO2- 4/ZrO2/USY was prepared by precipitation- dipping method. And the effects of different parameters on the conversion of cellulose to ethyl levulinate were also investigated. The results showed that 10% SO2- 4/ZrO2/USY presented the highest catalyst activity when calcined at 400 ℃ for 3 h, and the high yield (38.1 mol%) of EL was obtained at 200 ℃ for 3 h, with a catalyst dosage of 10 g/L. EL yields of 50.77mol%、39.55mol%、44.87mol% and 43.95mol% could be obtained from frutose, glucose, surcose and inulin, repectively. The catalysts were characterized by XRD、FT-IR、BET、NH3-TPD and TG-DTA. The prepared solid acid catalyst could be recycled and reused four times with good catalytic activity.
