This work focuses on the analysis of three types of adsorbents that can be used ill hydrogen Purification, for the Supply of vehicle fuel cells. This technique use., several adsorption columns filled with an adsorbent to obtain continuous operation of the hydrogen production process. Among the three adsorbents tested, the experimental Study leads to the choice of Amberlite XAD-4, which gives high adsorption capacity (up to 0.0620 kg(Tol).kg(XAD)(-1)) with good regeneration properties at low cost. Equilibrium data were fitted to the modified Drachsel isotherm equation. These data provide a useful reference in the design and assessment of the Purification process.
