| 英文摘要 | carbon capture with hydrogen-selective pd membranes can be realized as highly integrated process and co2 can be separated at high pressure without employing environmentally harmful sorption agents. this study investigates the technical viability of using ultrathin pd/ceramic composite membranes with innovative ceramic-to-metal connections under conditions that are practically interesting for natural gas-fired power stations, i.e. high feed and permeate pressures and high h-2 recovery at elevated temperature. the 90% co2 capture target was well exceeded during a 150 day test in water gas-shifted reformate at 673 k. after system stabilization 98% carbon were held back by the membrane while 98% h-2 were separated at nominally 99.5% h-2 purity. special attention has been paid to long-term operation effects on the 2-4 mu m thick pd layer. these include the development of a striking, cavernous pd morphology which increases mechanical stability of the composite membrane, a somewhat reduced but steady hy permeability, and the disappearance of most membrane defects. the latter is attributed to carbon deposits as exit flow analyses point to co2 reduction preserving effectively membrane selectivity. altogether, carbon capture with supported pd membranes projects as feasible from a technological vantage point.
