Abstract

Influence of different methods of microcrystalline cellulose (MCC) activation on its structure and reaction ability in hydrolysis reaction at 150 °C over acid-modified catalyst SBA-15 was studied. The most high cellulose conversion (70–82 % wt.) and glucose yield (27.0–37.5 % wt.) were achieved for MCC treated in ball-mill and for MCC activated in AGO-2 after treatment by water solution of alkali with urea. These activation methods reduce the degree of cellulose polymerization and its crystallinity index
