Abstract

Microwave energy was employed for the removal of NO_X by repetitive adsorption-desorption cycle over La_0.2Sr_0.8Co_1.0O_x(LSC)/H-ZSM-5 adsorbent having dual functions of NO_X adsorption and microwave absorption. The desired desorption temperature in the range from room temperature to 1000 °C was achieved successfully within 3 min by the control of LSC loading and microwave input power. The 25% LSC/H-ZSM-5 showed the highest sorption capacity of NO_X (0.130 mmol/g). It was found that the adsorption-desorption cycles were reversible and no deactivation was observed even after 10 repeated cycles. When the microwave is applied in the desorption step of NO_X, the desorption rate is 5 times faster than that of conventional thermal swing, which resulted in the enriched desorption of NO_X in percentage order. The desorption rate was further improved by the presence of water and ten times faster rate was obtained over the water adsorbed LSC/H-ZSM-5.
