Ultrasonic Pretreatment of Cow Dung for Anaerobic 网页2023年7月12日 · Ultrasonic pretreatment is an efficient method to enhance lignocellulose degradation and methane production, but the mechanism is not well studied. In this work, Research on the electrochemistry synergied cellulase enzymes 网页Lignocellulose degradation (LCD) was the key factor limiting the development of anaerobic fermentation (AF) by the cow dung (CD). In the research, the effects of cellulase pretreatment (CP) and micr...

Energetic Valorization of Biomethane Produced from Cow-Dung 网页2012年1月1日 · The fermentation of 440 kg of cow-dung in a 800 liter digester gave biogas production of 26.9 m3 with an average content of 61% in CH4, value considered optimal and energy equivalent to 592.8 MJ (164.5 kWh ). These results are encouraging for the use of cattle waste mass available in Algeria or even household waste. 5.
