In this study sorption-enhanced steam methane reforming (SE-SMR) in fixed beds is investigated by means of 1D numerical modelling, and the model is validated with the data reported in the literature. Isothermal conditions (973 K) are considered, and the equilibrium between the carbonation and calcination stages is shifted by a pressure swing: 3.5.10(6)Pa and 1013 Pa, respectively. The results showed that under these operating conditions at least 8 reactors in parallel are required to continuously produce a high-purity stream of H-2, and a separated stream of concentrated CO2. The average H-2 purity is 0.92, whilst the average H-2 yield and selectivity are 2.9 mol(H2) mol(CH4)(-1) and 90%, respectively. A thermodynamic analysis was performed, which highlighted that, by using a portion of the produced H-2 (about 0.4 mol(H2) mol(CH4)(-1)), it is possible to fully cover heat and power demands of the process, making it completely energy self-sufficient. In the case when the proposed SE-SMR is integrated with a solid oxide fuel cell, net power generation at the scale of similar to 950 kW(el) can be achieved with a net efficiency of the entire system of 51%, with the important feature that CO2 is concentrated.
