WebMar 20, 2024 · Dark Fermentation. The goal of dark fermentation (DF) is to produce hydrogen, whereas the goal of anaerobic digestion (AD) is to produce biogas, which can then be upgraded to biomethane. The distinction is in the operating conditions. Methanogens, a type of bacteria, decompose the acids into methane and carbon dioxide. WebApr 25, 2024 · La prima fase è costituita da una dark fermentation (fermentazione in assenza di luce) all’interno di termobioreattore. Il materiale di partenza (biomassa) viene fermentato in idrogeno molecolare, ioni idrogeno ed altri acidi organici dipendenti dal substrato di partenza. Tale bioconversione viene effettuata da particolari microrganismi ... WebThe fermentation reactors are modeled as operating at 55°C for a given batch time. The fermentation batch time was determined through a cost optimization study, by plotting projected hydrogen cost as a function of fermentation time (see Figure 2). Maximum fermentation time was limited to 74 hours, as NREL data showed maximum hays high school principal
