Adsorption of mercaptan on 13X loaded with Zn 2+ from model gasoline was studied at different concentration and temperatures. The results indicate that high temperature and low concentration favour the removal of mercaptan from the model gasoline. The adsorptive amount of the untreated adsorbents loaded with Zn 2+ is less than the treated with heat obviously, but the adsorbed amount is not enhanced distinctly by the way of increasing the treating temperature. A pseudo‐first‐order mechanism has been proposed to describe the adsorption in the model gasoline system. The desulphurizing capability increases due to the Zn 2+ impregnated. With the concentration of Zn 2+ higher, the adsorptive amount for ethanethiol increases. Adsorption mechanism shows that it is a chemical adsorption. Two different methods of regeneration were investigated.
