Notes:
Abstract Ni2+ exchanged and NiCl2 impregnated non-sulfided and sulfided NaY zeolites were characterized by xenon adsorption isotherms,129 Xe 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 samples.
