In the first stage of
biohydrogen production system, acetate and butyrate productions
were the main metabolism pathway. Therefore, acetate
and butyrate were used as indicators to predict the
performance of biohydrogen tank. The mass and energy
balance showed the main economic products such as biohydrogen,
biomethane, carbon dioxide, acetate, and butyrate
were able to be purified for further application. Therefore, the
commercial model could be established with market price
calculation from the simulation data.
