Summary
The climate crisis is an important worldwide issue that will continue to threaten the future unless serious measures are taken. The multidimensional energy sector directly affects many sectors such as industry, agriculture, tourism and logistics. Accordingly, it is important to ensure security of supply for countries with technological complexity other than developed countries. For this reason, it is necessary to enhance and develop uninterrupted energy sources such as modern renewable energy. The aim of this thesis, the production of biomethane as energy through the utilize of waste carbon dioxide gases instead of biomass, which is thought to contribute to this development with based on power to gas. In the study, different volumetric gas loadings and different operating temperatures that may affect biotechnological biomethane production were experimented. Experiments were carried out with upstream anaerobic sludge bed reactors (UASB) and anaerobic floc inoculum. Maximum achieved methane yields in mesophilic and thermophilic reactor operations are verimleri 53%, 69%, 70% and 69%, 66%, 60% respectively. The MFR values are 3.82, 7.11 and 15.54 m3/m3/day in the mesophilic reactor and 3.07, 5.03 and 11.97 m3/m3/day in the thermophilic reactor. In the mesophilic reactor, it was observed that the H2 consumption increased from 92.39% to 100% and the CO2 consumption decreased from 42.0% to 21.30% as the gas loading rate increased. On the other hand, H2 consumption decreased from 95.58% to 93.29%, and CO2 consumption decreased from 53.41% to 39.40% in the thermophilic reactor, Looking at the results of microbial attachment analysis, it was observed that there was microbial density at the bottom of the reactor in the mesophilic, and the microbial inventory was almost equally propogated in the thermophilic The result of the thesis study shows that the waste carbon dioxide gas formed in the industrial sectors in our country can be used as a fuel and can contribute within the framework of industrial symbiosis and sustainability issues.
