This study demonstrates the dark fermentative hydrogen gas production from waste peach pulp using intermittent feeding. The effects of hydraulic residence time (HRT) and substrate loading rate (SLR) on hydrogen production were investigated, showing that shorter HRTs and higher SLRs are more favorable for hydrogen formation. The maximum hydrogen formation rate of 931.8 mLH2/L.d was achieved with an HRT of 1 day and an SLR of 90 gTOC/L.d.
Peach has a big share of the world fruit market, with significant annual waste production. This study reports dark fermentative hydrogen gas production from waste peach pulp using intermittent feeding. In this context, the effects of hydraulic residence time (HRT) and substrate loading rate (SLR) on hydrogen production were determined in two sets of experiments. All experiments were performed in 310 mL serum bottles. During the first set of experiments, HRT was varied between 1 and 6 days and hydrogen production was more favorable at short HRTs. In the second set of experiments, SLR was varied between 9 and 90 gTOC/L.d, and more efficient hydrogen formation was observed by increasing the SLR. The most convenient HRT and SLR resulting in maximum hydrogen formation rate (931.8 mLH2/L.d) was obtained at 1 day and 90 gTOC/L.d, respectively. & COPY; 2023 Hydrogen Energy Publications LLC.
