An Investigation of Two-Stage Thermophilic and Mesophilic Fermentation Process for the Production of Hydrogen and Methane from Palm Oil Mill Effluent

The two-stage process of combined hydrogen and methane production with the recirculation of digestate sludge using palm oil mill effluent as substrate was investigated. During the first stage, an up-flow anaerobic sludge blanket reactor (UASB) was operated at thermophilic conditions [hydraulic reten...
