Abstract

Abstract: Pretreatment has a significant influence on hydrogen production from cellulosic materials by anaerobic fermentation. Microwave heating can change the crystal line structure of the fiber material to increase the hydrolysis degree of fiber. In this study, microwave pretreatments with H₂SO₄, HCl, H₂O, NaOH and NH₃·H₂O respectively were studied. The results showed that through microwave treatment of waste paper, the fiber hydrolysis rates during hydrogen production were higher than those of the untreated. Among them, it produced the highest hydrogen production rate of 44.6mL hydrogen from 1g fiber(calculates by volatile solid,S_V) after the treatment of microwave-NH₃·H₂O, while the untreated group produced only 13.7mL hydrogen/g fiber. Through microwave treatment of fiber material, fiber crystallinity was decreased, the accessibility of substrate was increased, but no change of chemical structure was found.

Key words: waste paper, cellulosic material, microwave, fiber
