Modeling of fermentative hydrogen production process

Abstract

Kinetic models can be used to describe relationship among the principal variables and to explain the behavior of fermentation quantitatively. In addition, it can provide useful information for the anaysis, design and operation of a fermentation process. Many kinetics models have been so far developed for the quantification of the fermentative hydrogen process. This review showed that, in general, the modified Gompertz model and the Anaerobic Digestion Model 1 (ADM1) can be easily used to desribe the progress of substrate degradation, hydrogen-producing bacteria growth, hydrogen production and some soluble metabolite production in a batch fermentative hydrogen production process. The correlation coefficient between the measured and fitted hydrogen evolution by modified the Gompertz model and ADM1 model were high and models were able to predict well the hydrogen profile.
