Physical Chemistry and Engineering for Adsorptive Gas Storage in Nanoporous Solids

Abstract

Adsorption gas storage is examined from physical chemistry point of view. Net, excess, and absolute adsorption are defined, and their relation to gas storage capacity is examined. Experimental techniques for measuring adsorption isotherms are detailed. Net adsorption particularly stands out among possible thermodynamic choices since it directly shows the advantage of having the adsorbent in a storage cylinder. In addition to storage capacity, engineering implications of Henry’s law constant, heat of adsorption, and multicomponent adsorption are examined with examples to inform material scientists who develop materials.
