Ceramic Membrane Reactors offer an opportunity towards the transition to renewable energies and defossilized economies by efficiently coupling chemical reactions heat utilization. To identify viable processes, mathematical models are needed that allow a straightforward assessment. In this study, generalized model is presented can be applied membrane reactor concepts using mixed oxygen transport membrane. The assumes equilibrium which realized minimizing Gibbs free energy in individual reaction chambers. Both chambers coupled Wagner equation account for ion flux through Experimental data from literature were used validate water splitting, partial oxidation of methane, these two processes. allows investigate various process parameters such as gas compositions, making particularly suitable feasibility studies initial design iterations new developments.
