Ni2+ exchanged and NiCl2 impregnated non-sulfided and sulfided NaY zeolites were characterized by xenon adsorption isotherms, Xe-129 NMR and thiophene hydrodesulfurization. The nickel species are located mainly inside the micropores of the zeolites in all samples. Ion-exchange results in a more homogeneous distribution of these species than impregnation. This explains their lower hydrodesulfurization activity compared to the ion-exchanged sample
