Dual phase membranes for high temperature CO2 separation
Doug Way | dway@mines.edu
Dual phase membranes selectively transport CO2 and are promising for potential applications in hydrogen production, natural gas separations, and energy conversion. These high temperature membranes consist of a molten carbonate (MC) salt supported in a porous, oxygen ion conducting ceramic. This class of materials is interesting because we can separate CO2 from a high temperature gas stream, such as a flue gas, without a phase change or any moving parts.

Student Preparation
Qualifications
Minimum: junior class standing in Chemical and Biological Engineering to start the project in the Fall of 2018. Preference given for students who have taken CBEN 375 Mass Transfer and have senior class standing.
Time Commitment
10-20 hours/month
Skills/Techniques Gained
Laboratory skills including membrane synthesis, performance measurements (CO2 flux and selectivity) and materials characterization skills (SEM, XRD, AFM).
Mentoring Plan
The student will work along side a post-doctoral fellow who will provide training on the experimental techniques. A former graduate student (Jake Newsom) will also be available to help train the new undergraduate researcher. We will have weekly meetings with Dr. Yang and Prof. Way.
