Activity of solid acid catalysts (based on SBA-15 and carbon Sibunit) in hydrolysis of sucrose at 80 °C and of microcrystalline cellulose (MCC) at 150 °C was compared. The maximal activity in sucrose hydrolysis (rate constant 9,2·10-4 s-1 ) was observed for SBA-15 containing anchored SO3H-groups. All studied catalysts increase the conversion of MCC in the following order (for hydrolysis time 12 h): without catalyst (4,2 % wt.) < Sibunit (16-19 % wt.) < acid Nafion® (21,5 % wt.) < SBA-15 (80,1 % wt.). Products of MCC hydrolysis contain along with glucose the oligosaccharides and impurities of mannose and xylose.
