Tests were performed to compress CO2 by 10 fold using a feed stream of 10% CO2 and 90% N2 at 1, 2, and 4 minute cycle times. With the initial testing, a compression ratio of 5.3 was achieved with 71 to 79% thermal recuperation efficiency. Subsequent modeling work has refined the design and the number of cells required to improve the overall system efficiency and simplify the process. These results indicate similar thermal efficiencies can be achieved using a system with only four cells rather than eight. Modeling results further demonstrate design changes required to obtain improved efficiencies and compression ratios. Results of both the original experimental work and the more recent modeling efforts will be presented.
