Enhancing Biogas Production with The Addition of Nano-catalysts

Abstract

: The province of Burdur is at the forefront of the livestock industry, especially with dairy cattle. it is a necessity for Burdur province to use animal manure, convert it into methane gas, and use it as fuel. In this study, a laboratory-scale biodigester was set up to produce biogas from cattle feces taken from Burdur Mehmet Akif Ersoy University Cattle Farm. γ-Fe2O3, meso-Fe2O3, and meso-Co3O4 nanoparticles (NPs) were synthesized and used as catalysts for biogas production. Structural characterizations of catalysts were carried out via FT-IR and XRD techniques. The TEM was used to investigate particle size distributions and morphology. The average particle sizes of the nanoparticles were determined to be in the range of 20-165 nm. The bio-digester was kept at a constant temperature of 35 °C for 20 days. It has been determined that the obtained biogas has a high methane content of 83–86%. The biogas volume was obtained to be 1.360 L/kg for γ-Fe2O3, 1.390 L/kg for meso-Fe2O3, and 625-1.250 L/kg for Co3O4.
