Abstract

This PhD thesis reports a systematic investigation into the effect of biochar in enhancing H2 and CH4 production in two-phase anaerobic digestion. It was found that the Fe-containing minerals, played a key role in promoting VFAs production and enhancing Clostridium butyricum population resulting in increased H₂ production and in promoting VFAs degradation and Clostridia and Methanosaeta growth, resulting in improved CH₄ production. Biochar was also found to support high organic loading rate operations in the two-phase anaerobic digestion process. It was also demonstrated that biochar can be an effective adsorbent for H₂S removal from the biogas.
