Abstract

CO2 capture membranes are a critical technology for the slow and halt of the issue of global warming, which is partly due to the large amount of CO2 emissions from coal-burning power plants in the form of flue gas. The current leading technology is an amine scrubbing membrane which, however effective, is far too costly and inefficient to be used commercially on a wide scale. My purpose in research this summer was in optimizing a prototype of a Mixed Electron Carbonate-Ion Capture membrane which is cost efficient and highly effective. The MECC is a semipermeable, dual-phase, self-forming membrane that combines the electron conducting properties of Ni at high temperatures with the ability of Molten-Carbonate to conduct CO32- to process CO2 and O2 while blocking other gasses from penetrating the membrane. A Micro-GC tester was used to obtain results from 5 different ratios of MC which were used to fill a porous NiO matrix and then tested for flux density of N2, O2, and CO2 to determine the ratio for best performance. Through both long term testing at 850°C and testing at various temperatures from 600°C to 850°C, yielded flux densities that indicated that a 54Li:46Na was the most optimal for the membrane.
