Abstract

Researchers are currently focusing on renewable energy as an alternative to fossil fuels. Anaerobic digestion is being utilized to reduce greenhouse gas emissions and create a sustainable energy supply. Hydrogen production from renewable sources is one of the most important ways to provide sustainable and clean energy, and today, hydrogen production is considered one of the most profitable transitory investments in green energy. Utilizing biogas for steam Reforming is an effective method for hydrogen production. This method, referred to as tri-reforming of methane (trm), enables the transformation of methane, CO2, Steam, and O2 to synthesis gas (a blend of CO2 and H2) while considering the composition of the biogas utilized, which includes oxygen in addition to methane and carbon dioxide. Trm combines methane, Partial Oxidation of Methane (POM), Steam Methane Reforming (SMR), and Dry Methane Reforming (DMR) in a single stage; biogas Reforming: water vapor and purified biogas are fed into the Reforming reactor. They are both maintained at 16 bar and 909 °C. 80% methane conversion is required. This section first explains how the PSA separation unit allows for hydrogen production with exceptional purity, reaching 75%, and the validation of the Aspen Plus model using experimental data and a Biogas production rate per day in the experimental test was 175 liters, which was obtained in the simulation for a loading rate of 19 liters per day, and the validation of the Aspen Plus model using experimental data, food waste as the base material, and carried out at a comparable concentration (CH4%) of 70%. The figure indicates that the industrial partner's hydrogen separation yield was 79%.
