A total of five adsorption/ desorption cycles for the C2H4/C2H6
mixture were completed on Na-ETS-10 for both microwave and
conductive heating. No mass loss of the adsorbent was observed after
each adsorption–desorption cycles, and the refreshed adsorbent bed
has the same weight as the starting adsorbent. A comparison of
microwave heating and conductive heating techniques over these
five cycles is presented in Fig. 3 and Table 1. The swing capacity of
Na-ETS-10 during microwave heating and conductive heating was
stable; 1.16 mmol/g Na-ETS-10 and 0.87 mmol/g Na-ETS-10, respectively over five cycles of adsorption/desorption (Fig. 3). The results
indicate that swing capacity of microwave heating is 1.33 times larger
than that of conductive heating. The swing capacity also indicates
that the adsorption capacity of Na-ETS-10 is not influenced by
successive microwave/conductive heating cycles.
