Hydrodesulfurization of thiophene on Ni-W and Ni-Re catalyst supported effect.

W, Re, MW and NiRe supported catalyst, on pillared clays (PILC), ultrastabl e zeolite (USY), active carbon (Carbon) and alumina (Al2O3) were prepared. The active fase and support influence in the reaction of hydrodesulfurizati on (HDS) of thiophene under atmosferic pressure and T= 400 degreesC have be en studied. The catalytic activities increases when the nickel is incorpora ted to the W monomethalic catalyst, in the four studied supports, and this difference is more notorius when the support is alumina: On the other hand, if nickel is incorporated to Re monomethalic catalyst, when the support ar e Carbon and Al2O3, no significant change is observed on the catalytic acti vities. When the used support are PILL and USY the Ni incorporation decreas es the catalytic activity. The catalytic activity results are discussed in function of some properties of the support and catalyst, and possible siner gic and antagonic effects that would be generated.
