Modeling and Simulation of a Nonisothermal Catalytic Membrane Reactor

New high temperature sealing technique and permeability data for hollow fiber BSCF perovskite membranes

“…Although not yet implemented at industrial scale, an area of great interest for perovskite membranes is their integration in membrane reactors for high temperature syngas production, such as in the catalytic partial oxidation and autothermal reforming (ATR) of methane [2][3][4][5][6][7][8]. Hollow fiber membranes in particular can ensure a high surface area per unit volume compared to other configurations (planar or tubular) and can be produced with a small wall thickness (typically 0.1-0.5 mm), enhancing oxygen transport rates.…”

Experimental and modeling studies on Ba0.5Sr0.5Co0.8Fe0.2O3−δ (BSCF) tubular membranes for air separation

“…The dense thin membrane film is supported on a porous sub-layer, in turn, supported on layers with larger pore dimensions also made from an oxygen permeable material, in order to minimize differential expansion effects. However, when compared with the development of membrane materials and the experiments of performance evaluation, relatively little work has been reported on the theoretical analysis and process simulation [15][16][17]. Tsai et al developed a two-dimensional non-isothermal mathematical model to simulate the partial oxidation of methane to syngas in a mixed-conducting membrane reactor.…”

Material properties and operating configurations of membrane reactors for propane dehydrogenation

“…Tsai et al carried out nonisothermal modeling for partial oxidation of methane and studied temperature profiles in adiabatic operating conditions. 20 Shelepova et al developed a model of combined oxidation of hydrogen (exothermic) in the shell side with PDH (endothermic) in the tube. 21 Modeling of countercurrent sweep gas configuration has also been studied and compared with cocurrent mode by several research groups.…”
