Kinetic study of glucose production from cellobiose through hydrolysis has been performed to compare reaction characteristics by using reaction models with β-glucosidase (Trichoderma reesei) and with graphenebased amorphous solid acid catalyst (SAC). The decrease of cellobiose concentration through hydrolysis with β-glucosidase is inhibited by present glucose as reported, resulting in unreacted cellobiose remained for a long time. In contrast cellobiose concentration decreased with SAC obeying 1st reaction rate model, showing relatively rapid reaction rate without such inhibition observed in hydrolysis with β-glucosidase. By using the plug flow reactor with a SAC packing column, an attempt of catalytic aging experiment was carried out about over 4,000 h, succeeding in construction of the 1st order reaction rate model.
