Oxygen Permeable Membrane

 

Ion transport membranes (ITM) are made of high temperature ceramics, which has been studied for many useful chemical reactions. Based on the fact that only oxygen ions can transport through an oxygen-transport ITM, we have developed an ITM reactor concept for CO2/H2O dissociation and syngas production. The CO2/H2O molecules will dissociate and the oxygen ions will transport through the membrane, leaving CO and H2 in the feed side. On the other side of the membrane reactor, i.e. sweep side, the oxygen ions will recombine into oxygen molecules or react with CH4 to produce syngas. With this new technology, the CO2 produced from power plants can be reformed into useful fuel, not only reducing the carbon footprint of power plants but also adding values to the greenhouse gas.

In order to understand and improve the mechanism related to CO2/H2O dissociation on ion transport membranes, we have built an ITM reactor to study the mass transport phenomena, thermodynamics and chemical kinetics in the processes. Methods such as XRD and SEM will be applied to characterize the membranes.

The focus of current work is to study the hydrogen/syngas production process and develop the reaction kinetics.
