In these equations, CA is the adsorbed concentration for the species components, which is dependent on the adsorbent material, gas mass fraction, pressure, and temperature. The method of calculating is addressed later, where criteria for the selection of the adsorbent are discussed. Cw,i CA,i  t  t (2.8) (2.9)  D Cw,i  Cg,i Cw,i zeff,i zAR   w c Twk2Tw eq,Mass,i Tg Tw w p,w t H i ads,i w z2 CA,i  t Aw Req,Heat Tw TFS Aw Req,Heat,FS The source terms in the energy equation include heat transfer from the microchannel to the adsorbent layer, heat transfer from the adsorbent layer to the fused silica wall, and the volumetric rate of heat generation due to adsorption for all component 26
