| Abstract Scope |
A high-temperature ceramic-carbonate dual-phase (CCDP) tubular membrane composed of a porous scandium stabilized zirconia (ScSZ) ceramic phase filled with a Li-Na molten carbonate (MC) phase is presented for CO2 capture. Such ScSZ-MC tubular membranes show outstanding CO2 permeability at temperature range of 650-950C. In addition, the wettability of ScSZ phase to MC phase was further enhanced via wet-impregnation of Al2O3 as well as doping with yttria-stabilized zirconia (YSZ) and NiO for elevated pressure application. Moreover, the effect of introducing H2O into sweep stream was evaluated for the tubular ScSZ-MC, showing improved CO2 permeability due to the co-conduction of CO32- and proton (OH-). |
