NaY zeolites, ion-exchanged by Ni 2+ , are investigated by xenon adsorption and by 129 Xe NMR. Sulfided and nonsulfided samples are compared. In addition sulfided samples are characterized by thiophene hydrodesulfurization (HDS). The nickel species a

Al-pillared clays, prepared by exchange with partly hydrolyzed aluminium nitrate solutions, dried in air or freeze-dried, and calcined, were used as supports for nickel sulfide catalysts. The catalysts were tested on their hydrodesulfurization (HDS)

A new assignment of the signals in the 23Na DOR NMR spectra to the different sodium sites in dehydrated NaY zeolite is presented. 23Na DOR and MASNMR measurements of dehydrated NaY, Ca2+-exchanged NaY samples, and NaY samples in which Mo(CO)6 is adso

NaY supported Mo or Ni sulfide catalysts prepared by impregnation, ion exchange or gas phase deposition followed by various pretreatment procedures show different catalytic properties in thiophene hydrodesulfurization. These differences are discussed

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 i
