conversion loss combined with the waste heat produced from the consumption of direct primary energy amounts to nearly 43 EJ of waste heat available at temperatures greater than 30°C (Rattner and Garimella, 2011). As conventional fuels become more constrained, the need to manage the available primary energy resources intelligently is becoming critical, until renewable energy sources can effectively replace the current energy supply landscape. Judicious management of energy requires the utilization of low- grade waste heat from power and other industries for thermal applications. Accordingly, thermally driven systems can replace electrically driven systems that may increase the carbon load on the environment. This transition will eventually lead to reduced burden on power industries, reduced use of conventional energy sources, and reduced carbon footprint, while retaining overall energy sufficiency, addressing the fourth impacting factor in CO2 emission mentioned above. One such energy technology pertaining to gas separation that can reduce the use of direct electricity for its operation is the temperature swing adsorption (TSA) process. 1.3 Motivation for the present work The thermodynamic state of an adsorbent can be manipulated by altering either the partial pressure or the temperature of the surrounding gas adsorbate to cause adsorption or desorption. Existing adsorption-based systems prefer pressure swing adsorption (PSA) over temperature swing adsorption (TSA). Conventional adsorbent beds are prepared by filling the adsorbent pellets in rigid cylinders, allowing porous regions between adsorbent particles for the gases to flow. In a PSA process, compressors are incorporated into the system for pressurization and depressurization of the adsorbent, thus consuming electricity. Additionally, these processes are slow due to large mass 5PDF Image | TEMPERATURE SWING ADSORPTION PROCESSES FOR GAS SEPARATION
