【 摘 要 】

This work investigates the performance of a fluidized-bed membrane reactor for pure hydrogen production. A techno-economic assessment of a plant with the production ca-pacity of 100 kgH2/day was carried out, evaluating the optimum design of the system in terms of reactor size (diameter and number of membranes) and operating pressures. Starting from a biomass source, hydrogen production through autothermal reforming of two different feedstock, biogas and biomethane, is compared.Results in terms of efficiency indicates that biomethane outperforms biogas as feed-stock for the system, both from the reactor (97.4% vs 97.0%) and the overall system effi-ciency (63.7% vs 62.7%) point of views. Nevertheless, looking at the final LCOH, the additionalcost of biomethane leads to a higher cost of the hydrogen produced (4.62 euro/kgH2@20 bar vs 4.39 euro/kgH2@20 bar), indicating that at the current price biogas is the more convenient choice.
