Abstract
Changing the order in which oxidic W and Ni convert to sulfides by adding 1 ,2-cyclohexanediamine-N,N,N',N'-tetraacetic acid (CyDTA) as a chelating age nt for nickel in the preparation of NiWS-SiO2 catalysts is the key ingredie nt in obtaining a high activity for thiophene hydrodesulfurization.
