Abstract

© 2021, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.Different additives are used to enhance the microbial activity and ensure the suitable environment for anaerobic microorganisms in anaerobic digestion (AD) process. This study aims to investigate biogas production activity by adding mica particles (MP) and SnO2 nanoparticles (NPs)-doped mica (MSnO2) preparing by co-precipitation. The morphological and structural investigations of particles prove that the SnO2 NPs have been successfully embedded on mica surface. The deposition of SnO2 on the mica surfaces contributes the catalytic performance which in turn improves biogas production. The concentration of MP and MSnO2 was adjusted to be 0.03 mg/L and 0.06 mg/L for the biogas production experiment. In batch experiments, the highest biogas production, biogas yield, and methane yield were obtained at MSnO2-1 (0.03 mg/L) with 6890.2 mL, 245.4 ml/gVS, and 162.3 mL CH4/gVS, respectively. The addition of 0.03 mg/L MSnO2 increased biogas yield by 18.1% and methane yield by 33%, in the light of the data acquired from this experimental study that MSnO2 and pristine mica can be used effectively to enhance biogas production from cattle manure (CM).
