Highly stable dual-phase Y0.8Ca0.2Cr0.8Co0.2O3–Sm0.2Ce0.8O1.9 ceramic composite membrane for oxygen separation

A novel CO2- and SO2-tolerant dual phase composite membrane for oxygen separation.

A novel dual phase composite oxygen transport membrane (Al0.02Ga0.02Zn0.96O1.02-Gd0.1Ce0.9O1.95-δ) was successfully prepared and tested. This membrane shows chemical stability against CO2 and SO2, and stable oxygen permeation over 300 hours in CO2 was demonstrated. ZnO is cheap and non-toxic and is therefore highly advantageous compared to other common materials used for this purpose.

An asymmetric tubular ceramic-carbonate dual phase membrane for high temperature CO2 separation.

For the first time, a tubular asymmetric ceramic-carbonate dual phase membrane was prepared by a centrifugal casting technique and used for high temperature CO2 separation. This membrane shows high CO2 permeation flux and permeance.

Preparation and characterization of polyethylene/ glass fiber composite membrane prepared via thermally induced phase separation method

Grinded glass fiber (GGF) embedded high density polyethylene (HDPE) membranes were prepared via thermally induced phase separation method. FESEM images showed that all the membranes had leafy structure, indicating a solid-liquid mechanism during phase separation. The results of EDX and TGA analyses confirmed that the fibers were dispersed in the HDPE matrix uniformly. Normalized water flux of t...

A novel CO2-stable dual phase membrane with high oxygen permeability.

By cobalt-doping of the mixed conducting phase PSFC, a good combination of high CO2 stability and high oxygen permeability is obtained for the 60 wt% Ce(0.9)Pr(0.1)O(2-δ)-40 wt% Pr(0.6)Sr(0.4)Fe(0.5)Co(0.5)O(3-δ) (CP-PSFC) dual phase membrane, which suggests that CP-PSFC is a promising membrane for industrial applications in the oxyfuel process for CO2 capture.
