Influence Of Mechanical And Chemical Activation Of Microcrystalline Cellulose On Its Structure And Reaction Ability In Hydrolysis Over Solid Acid Catalyst Sba-15

Influence of different methods of microcrystalline cellulose (MCC) activation on its structure and reaction ability in hydrolysis reaction at 150 degrees 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.
