| Abstract: | An isothermal theoretical model for tubular perovskite dense membrane reactors has been developed for the simulation of methane partial oxidation to synthesis gas. The reaction kinetic rate expressions fitted to the literature experimental data for Ni/al_2O3 catalysts are used for simulation. Three dense membranes of La(0.2)Ba(0.8)Fe(0.8)Co(0.2)O(3-|?), La(0.2)Sr(0.8)Sr(0. 8)Co(0.2)O(3-|?) and SrFeCo(0.5)Ox with different oxygen permeation rates are applied to membrane reactors. |
