In this study the performance of an Expanded Granular Sludge Bed (EGSB) reactor for biological production of hydrogen was modeled using computational fluid dynamics. The effect of differentHydraulic Retention Time (HRT) of 1, 2 and 4 hr and Glucose mass fraction in feed of 0.002,0.004, 0.006, and 0.008 on Hydrogen production rate was determined. The maximum value of H2production rate at the HRT of equal to 2h and Glucose mass fraction of 0.008 is 0.033 kg/h . It wasdemonstrated that the model is capable of predicting the variation of the EGSB reactorperformance for biohydrogen production at various substrate concentrations and HRT values.
