Experimental evaluation of continuous in-situ biomethanation of CO2 in anaerobic digesters fed on sewage sludge and food waste, and the influence of hydrogen gas-liquid mass transfer

This data repository collects all the experimental data related to the paper "Experimental evaluation of continuous in-situ biomethanation of CO2 in anaerobic digesters fed on sewage sludge and food waste, and the influence of hydrogen gas-liquid mass transfer". <br> The data is divided in two main folders, according to the substrate used in the biomethanation experiments, i.e.: - Sewage Sludge (SS) - Food waste (FW) <br> In each substrate folder, the data is further reported in different folders, for each of the experimental periods - R1 , R2, R3 (gas recirculation rate experiments) - O1, O2, O3 (operational conditions experiments) <br> For each experimental period, three Excel (*.xlsx) files are included: - Organic Loading Rate (OLR), Biogas Flow and H2 Injection - Gas Composition - pH <br> Each experimental period is described in detail in the PhD Thesis: "Sastraatmaja, A. Experimental Process Development and Techno-Economic Assessment of In-Situ Biomethanation of Carbon Dioxide in Biowaste Anaerobic Digesters, University of Sheffield, 2022." Graphs from PhD Thesis are included in each Excel file to facilitate referencing. <br> <br>
