Continuous Fermentative Hydrogen Production from Brown Sugar Using EGSB Reactor
In this experiment, brown sugar was chosen as the substrate of continuous operation. A lab-scale expanded granular sludge blanket (EGSB) reactor was employed. Stable ethanol-type fermentation was formed by controlling the organic loading rate (OLR). The results showed a maximum hydrogen production rate of 5.73L / L reactor•d was achieved, under the condition that the hydraulic retention time (HRT) = 2h, OLR = 97.2kg COD/m3 reactor•d. The average hydrogen content in the biogas during the 73-day operation was 41.27%.
