Effect of Low Concentration Alkali and Ultrasound Combination Pretreatment on Biogas Production by Stalk

Abstract:

Article Preview

Rice stalk were pretreated using low concentration alkali and ultrasound combination pretreatment, biogas anaerobic fermentation were used to estimate the pretreatment. The results showed that daily mean biogas production using combined pretreatment stalk was 35.32-48.42% higher than that merely using low concentration alkali pretreatment stalk, 67.79-76.65% higher than that of unpretreated stalk. pH of fermentation broth showed no difference using different pretreatment methods. The content of lignin in lignocellulose were remarkably decreased when low concentration alkali and ultrasound combination pretreatment was used to deal with stalk, almost 41.01% lignin in stalk degraded.
