Overview

Randomized trial demonstrates hydrogen production from palm oil mill effluent, suggesting a promising bioenergy solution.

Key Points

This research aims to explore the potential of palm oil mill effluent (POME) for hydrogen production through dark fermentation and analyze key processing variables.
Experimental evaluation of thermal pretreatment of anaerobic sludge to enhance H2 yields.
Scale-up from 300 mL to 7000 mL to assess process feasibility.
Anaerobic digestion of effluent to measure methane production and COD reduction.
Best H2 conditions yielded 36 N-mL/L.g COD with productivity of 32 N-mL/L.h and specific production of 1423 ± 130 N-mL/L.
Scale-up maintained comparable performance between 300 mL and 7000 mL reactors.
Subsequent anaerobic digestion achieved methane production of 2918 N-mL/L and 57% COD reduction in 35 days.
