Abstract

Adsorption of methanol vapors on zeolite-4A and metals (Co, Ni, and Cu) exchanged zeolite-A has been studied as a function of temperature. Thermodynamic parameters such as Go, H, and So are calculated. It is observed that in most of the cases, metal exchanged zeolite samples have more adsorption affinity towards methanol as compared to parent zeolite. From adsorption data isosteric heat of adsorption were also calculated as a function of coverage and temperature, which is similar to - H.
