This work presents the study of the interaction of microwaves with commercial CO2 and water adsorbents, and the identification of the potential benefits of the microwave technology as a source of heat to be implemented for post-combustion carbon capture by means of thermal-swing adsorption. Experimental results on microwave swing regeneration for both, CO2 and water-loaded adsorbents (13X zeolite, micro and mesoporous commercial silica gel (FS), and activated alumina (F-200)) are discussed along this work. Results were evaluated based on the heating rate of materials after their exposure to microwaves, the resultant adsorbate desorption, and the specific regeneration energy. It was found that 13X zeolite is a strong microwave absorber, which has the ability to increase the temperature in a matter of seconds when moisten, dry or loaded with CO2, and exposed to microwaves. The complete regeneration of CO2 from 13X was achieved after 8 min under a controlled microwave heating at 140°C.
