Many foods and beverages use fructose syrup as a sweetener and it is known that the sweetness level of fructose is higher than sucrose. Fructose can be produced through isomerization of glucose obtained from the hydrolysis reaction of cellulose. This study aims to predict the performance of the simultaneous reaction of hydrolysis of cellulose to glucose and the isomerization of glucose to fructose in one reactor via kinetic model simulation using software. This study presents a kinetic model consisting of hydrolysis of cellulose and isomerization of glucose into fructose. The modeling and simulation carried out in this study used secondary data in the form of initial substrate concentration and product concentration obtained from literature data to determine the reaction kinetics parameters of each catalyst. After that, a schematic of the temperature and pH range of the selected catalyst was made. From the scheme it will be seen which regions are possible for the two catalysts of the hydrolysis reaction and the isomerization reaction to be combined. Then the simulation was carried out using the MATLAB R2016a software. The results of this study indicate that based on the modeling that has been done, the hydrolysis reaction and the isomerization reaction can be carried out simultaneously in one reactor using a combination of H2SO4 and Mg2Al- HT; H2SO4 and Arginin; CaFe2-O4 and Mg2Al-HT; H3PW12O40 and Mg2Al-HT; H3PW12O40 and TEA; and HT-OHca and Mg2Al-HT.
