Exploring the Processing of Tubular Chromite- and Zirconia-Based Oxygen Transport Membranes
Abstract
Tubular oxygen transport membranes (OTMs) that can be directlyintegrated in high temperature processes have a large potential toreduce CO<sub>2</sub> emissions. However, the challenging processing ofthese multilayered tubes, combined with strict material stabilityrequirements, has so far hindered such a direct integration. We haveinvestigated if a porous support based on (Y<sub>2</sub>O<sub>3</sub>)<sub>0.03</sub>(ZrO<sub>2</sub>)<sub>0.97</sub> (3YSZ) with a dense composite oxygen membrane consisting of (Y<sub>2</sub>O<sub>3</sub>)<sub>0.01</sub>(Sc<sub>2</sub>O<sub>3</sub>)<sub>0.10</sub>(ZrO<sub>2</sub>)<sub>0.89</sub> (10Sc1YSZ) as an ionic conductor and LaCr<sub>0.85</sub>Cu<sub>0.10</sub>Ni<sub>0.05</sub>O<sub>3−δ</sub>(LCCN) as an electronic conductor could be fabricated as a tubularcomponent, since these materials would provide outstanding chemical andmechanical stability. Tubular components were made by extrusion, dipcoating, and co-sintering, and their chemical and mechanical integritywas evaluated. Sufficient gas permeability (≥10<sup>−14</sup> m<sup>2</sup>)and mechanical strength (≥50 MPa) were achieved with extruded 3YSZporous support tubes. The high co-sintering temperature required todensify the 10ScYSZ/LCCN membrane on the porous support, however, causeschallenges related to the evaporation of chromium from the membrane.This chemical degradation caused loss of the LCCN electronic conductingphase and the formation of secondary lanthanum zirconate compounds andfractures. LCCN is therefore not suitable as the electronic conductor ina tubular OTM, unless means to lower the sintering temperature andreduce the chromium evaporation are found that are applicable to thelarge-scale fabrication of tubular components.
