Abstract

Four different pretreatment methods including steam explosion pretreatment, H₂SO₄ pretreatment, NaOH pretreatment and NH₃·H₂O pretreatment were tested to improve bio-hydrogen production from corn stalk. Clostridium sp.X₉ was used to investigate H₂ production directly from corn stalks fermentation. Results show that steam explosion pretreatment is the best one. Under the optimal pretreatment conditions (ψ(H₂SO₄)=1%, 121°C, 2 h), the maximum yield of H₂ is 6.4 mmol/g and degradation rate of corn stalk is 47.8%. The liquid end-products mainly contain butyrate, acetate and ethanol.
