Thermal management and optimization of adsorption vessels for CO2-based green refrigeration systems: A heat and mass transfer approach

Experimental Investigation and Thermodynamic Analysis of Coconut-Shell-Derived Activated Carbon for CO2-Based Advanced Adsorption Cooling Systems

“…In continuation, with respect to ADCS, it offers various advantages, like it can be easily driven by low-grade energy sources like waste heat, solar, or exhaust coming out of the automobile and multiple industries; thus, suitable for stationary and mobile applications. − Various adsorbents can be employed in ADCS or any other sorption-based systems, like MOFs, zeolites, and activated carbons (ACs) out of which ACs are preferred because they offer several advantages over other adsorbents, viz less cost, easy and cheap synthesis, insensitivity toward moisture, good thermal stability, higher CO 2 adsorption affinity, faster kinetics, higher surface area, better pore size distribution, tunable pore structure, low energy requirements for regeneration, and excellent chemical stability and resistance toward both acidic and alkaline environments. − There are many precursors from which ACs can be developed, out of which biomass or waste biomass resources can be a potential precursor as it enables an environmentally friendly approach, and most importantly, the biomass precursors are readily available in abundance and cheap.…”
