Until now, the emphasis of the continuous experiments has primarily been on capture. However, in a continuous process, the role of regeneration is equally essential. To study the dynamics of regeneration, measurements over full capture-regeneration cycles are done using N 2 -CO 2 feed gas compositions of 5, 10, 15, and 40 mol% of CO 2 . With the exception of the 40 mol% case, all experiments are conducted at 233 K, 40 bar, and 1.0 slm of inlet flow rate. The 40 mol% case is done using the same temperature but at 20 bar and 0.5 slm to prevent the liquefaction of CO 2 . The capture phase is identical to that discussed in the previous section. Regeneration is triggered by reducing the reactor pressure slowly to 1 atm by closing the reactor inlet while maintaining a constant flow rate at the reactor outlet. This is preferred over a more rapid decompression to avoid self-preservation , which is assumed to play a major role in the regeneration phase but has not been addressed in detail.
