摘要: Nanostructured gas separation membranes are promising candidates for the of CO(2) from flue fossil power plants. Well-defined atomic structures in range a few Angstrom required to separate N(2) existing post-combustion plants, and H(2) prospective integrated gasification combined cycle (IGCC) Today, CO(2)/N(2) H(2)/CO(2) with has been demonstrated mainly on laboratory scale, while less is known about membrane performance stability under real conditions. To extend state knowledge, test bed was put into operation stream hard-coal-fired plant (EnBW Rheinhafendampfkraftwerk, Karlsruhe), which enabled long-term functional ceramic as well polymer up 1100 h. For first time, enrichment 12 vol.% 57 permeate demonstrated. Due operating this direct contact gas, flow rate reduced 0.86 0.07 m(3)/m(2) h bar within 400 This reduction caused by deposition ash particles gypsum suggesting need developing effective protection strategies. In addition, supported Ti(0.5)Zr(0.5)O(2) metal Co-SiO(2) were tested same Even if demonstration requires further modifications materials, exposure led notable results regarding adherence layers chemical stability.
