    Enhancing the production of biogas through anaerobic co-digestion of agricultural waste and chemical pre-treatments حسب Almomani F.

    منشور في 2020
    "…The results revealed that the highest cumulative methane production (CMP) of 297.99 NL/kgVS can be generated by co-digestion of ASWs and CD at a ratio of 60:40. Further improvement was achieved via alkalinity treatment with 1.0 g of NaHCO3/gVS leading to decrease in lignin, cellulose, and hemicellulose contents of feedstock by 3.5%, 10.5% and 15.9%, respectively, converting them to soluble fractions and improving the CMP by 11.2–29.7% based on substrate quality. …"
