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