What is the difference between dark fermentation and photo-fermentation?
At 30 °C and 33 °C in the dark fermentation system, 24 and 27 °C in the photo-fermentation system, the hydrogen production is affected by temperature fluctuations and is greater than that of the constant temperature system at the same initial temperature.
How long does a fermentation process last?
During the first 12 h of fermentation, the system temperature at different initial temperatures increases to a large extent. The system temperature rises slowly from 12 to 20 h, and remains basically stable after 20 h.
How much energy is needed for enzymolysis & fermentation?
For the enzymolysis stage, the energy required includes both heat to maintain the hydrolysis temperature and mechanical energy for the agitator operation. During the fermentation stage, energy consumption mainly comes from feeding devices, lighting devices, mixing devices, and online monitoring systems.
Can a two-phase anaerobic digester maintain a steady fermentation temperature?
However, intermittent solar radiation and low ambient temperature in the winter make it difficult to maintain a steady fermentation temperature. In this study, a pilot-scale two-phase anaerobic digester combined with solar thermal and phase change thermal storage (PCTS) system has been constructed.
What are the advantages of biological fermentation hydrogen production?
Compared to green hydrogen production via water electrolysis, the biological fermentation hydrogen production system exhibits advantages in resource recycling and simultaneously achieving waste treatment and clean energy production.
Can dark fermentation be used as a substrate for photo fermentation?
Based on the hydrogen production mechanisms of dark fermentation and photo fermentation, the fermentation liquid, which leaves the dark fermentation, can be adopted as the substrate for photo fermentation.
