The effects of catalyst amount on the yields of levulinic and hydroxymethyl furfural were investigated during conversion of glucose to levulinic acid catalyzed by solid super acid SO42- / TiO2-Al2O3-SnO2. XRD and XPS were used to analyse the characteristics of solid super acid SO42- / TiO2-Al2O3-SnO2 before reaction and after reaction. The results showed that: solid super acid SO42- / TiO2-Al2O3-SnO2exhibited good catalytic activity in the reaction of hydrolysis of glucose to produce levulinic acid. There were three obvious peaks in these XRD spectra. The peaks on 44.6° and 67.1° were the characteristic diffraction peaks of γ-Al2O3. The anatase characteristic diffraction peak was on 37.4°. The catalyst was steady in the process. The binding energy of S 2p was similar to the binding energy of standard S6+ 2p in the S 2p XPS spectrum of solid super acid. O 1s XPS was double-peaked spectrum. The increase of element C was the main reason of inactivation of catalyst.
