Technology Research on Bio-Hydrogen Production

Hydrogen as a clean and renewable energy plays very important role in both of relief severe shortage of petroleum and deterioration of ecological environment. Fermentative hydrogen production from organic wastes plays the dual role of waste reduction and energy production. In this paper, the characteristics of biological hydrogen production by mixed cultures were investigated in batch tests; several modified kinetic models describing the biological hydrogen production were developed. The results show that the modified Logistic model could describe the variation of hydrogen production potential with time; the modified Ratkowsky model could describe the effects of temperature and initial pH on average hydrogen production rate successfully.
