The optimization and statistical analysis of fermentative hydrogen production using Taguchi method

Abstract

AbstractThere are many variables influencing the performance of fermentative hydrogen production. The present paper tries to scrutinize and improve the rate and efficiency of fermentative hydrogen production through modeling and optimizing the effective parameters or variables on fermentative process. In this research, Taguchi experimental design method are applied to design the experiments. Then, the experimental results are analyzed by Design Expert software. Eventually, the optimization of process with considering the experimental data is implemented and their results are reported. The optimum conditions of bio hydrogen production and their predicted responses have been resulted in inoculums size of 11%, an initial glucose concentration of 10.13 g/L, initial pH of medium of 6.18 and FeSO4·7H2O concentration of 30 mg/L. The yield of hydrogen is 2.86 mol of hydrogen per mole. glucose with the production rate of 3.21 mol of hydrogen per hour.
