Adsorption equilibrium data are the most essential information needed for the design and development of adsorption systems. It describes the amount of adsorbate that could be adsorbed onto the surface of a certain mass of adsorbent at a given equilibrium pressure and temperature. Even though the practical adsorption processes are unequilibrium and controlled mainly by the adsorption rate, accurate equilibrium data are crucial to simulate the dynamic behavior of the adsorption system. In addition, these data are also necessary for an accurate evaluation of isosteric heat of adsorption. The present chapter provides a brief description of the most common techniques used for measuring adsorption equilibrium. This study focuses mainly on the adsorbent/adsorbate pairs applicable on adsorption cooling and heat pump systems. Selective representative examples have been discussed. Advantages and disadvantages of each measuring method have also been presented.
