| Popis: | The effect of ultrasonic pretreatment on biogas production from rice straw was investigated. Results showed that the application of 37 and 102 kHz resulted in a reduction of hemicellulose about 25.78% and 20.82%, respectively. An increase in the power level and exposition time decreased the hemicellulose content. The biochemical methane potential values at 37 kHz and 102 kHz of the pretreated rice straw for a period of 45 days were 250.36 and 243.79 mL CH4 g VS-1added, which were about 21.95% and 18.75% increase compared to the unpretreated one, respectively. The pretreatment with 37 kHz has provided a better methane yield compared to the one with 102 kHz. Response surface methodology indicated a positive result toward the methane yield and production rate. The utilization of ultrasonic pretreatment toward rice straw for biogas production seems to provide a solution to help solving the problems of both agricultural waste and renewable energy. |
