Simultaneous overcome of the equilibrium limitations in BSCF oxygen-permeable membrane reactors: Water splitting and methane coupling

Strength and elastic modulus of lanthanum strontium cobalt ferrite membrane materials

“…Mixed ionic electronic conducting (MIEC) ceramic membranes are an interesting option for oxygen supply in industrial processes and to implement carbon capture concepts in fossil power plants [1,2]. Especially in the OXYFUEL process, the use of membranes promises the lowest losses in power plant efficiency compared to the conventional methods.…”

Mechanical properties of pure and doped cerium oxide

“…4 In particular, gadolinium doped cerium (Ce 0.9 Gd 0.1 O 1.95−δ ), that is also widely used in solid oxide fuel cells, 5 was suggested as oxygen transport material for syngas production, 6 due to its chemical stability. 7 However, the functional properties of the doped ceria-oxides need still to be optimized with respect to sintering behavior and electronic conductivity by substitution or doping.…”

Limiting and achievable efficiencies for solar thermal hydrogen production

“…4 has the potential to minimize water recycle through complete conversion, and operate at lower temperatures (<2000 K) to possibly avoid material limitations issues. Recent experiments with membrane reactors withdrawing O 2 (g) alone have reported 9% water conversion at temperatures near 1200 K and 1 atm [39,40], while the equilibrium conversion is w1.1 Â 10 À5 . The high conversion of 9% was attained by simultaneously consuming O 2 (g) via reaction on the permeate side of the membrane.…”
