Project Description

The University of South Carolina is studying high-performance and economically competitive ceramic membrane technology for air separation and high-purity oxygen production at temperatures less than 700 degrees Celsius (°C). The objective of the project is to carry out advancement of nanostructured ceramic hollow fiber oxygen permeation membranes by combining material advantages with microstructure advantages through advanced fabrication technologies. The primary focus of the research is on ceramic materials synthesis and innovation, systematic screening and identification of materials suitable for high-performance oxygen separation membranes, and the fabrication of nanostructured ceramic hollow fiber membrane devices, as well as evaluation of the oxygen permeation performance and durability of thin-film hollow fiber membranes for oxygen production.

Project Benefits

The University of South Carolina project, by employing nanotechnology and advanced fabrication technology to fabricate nanostructured ceramic hollow fiber membranes, will lead to low cost and high performance for high-purity oxygen production. The reduced operating temperature (less than 700°C) may significantly improve the durability of separation membranes while reducing the cost of the system operations. It is expected that the resultant membranes may be easily scaled up and will be able to fulfill the requirements for production rate and oxygen purity to support oxygen-intensive industries, such as energy production (e.g., integrated gasification combined cycle and oxy-combustion systems), fuels, chemicals, and other industries (e.g., steel, cement, glass, etc.).
