Comparison Study of Experimental and Simulation in the Glucose Isomerisation Process in a Fixed-Bed Reactor

Abstract:

Production of fructose from glucose isomerisation process using commercial immobilized glucose isomerase (IGI) was conducted in a fixed-bed bioreactor. A semi-empirical kinetic model based on the mechanism of the glucose isomerisation process has been proposed. The values of maximum rate of reaction, V_m ,g L^-1 min^-1 are (1.82, 1.86, 1.93 and 0.37), for Michaelis-Menten constant K_m, g L^-1 the values are (1.04, 1.11, 1.24 and 0.35). In this modified model, known as MM3 the variation of temperature, pH, and initial substrate concentration, feed flow rates have been taken into account. The validation of the models with experimental data was checked in terms of AAE and R². The values of correlation coefficient, R² (> 0.95) indicated that MM3 model was well fitted to the experimental data.
