Resumen

ALVEZ, G. et al. HIDRODESULFURACIÓN DE TIOFENO SOBRE CATALIZADORES Ni-W Y Ni-Re. EFECTO DEL SOPORTE. Bol. Soc. Chil. Quím. [online]. 2001, vol.46, n.3, pp.363-372. ISSN 0366-1644.  http://dx.doi.org/10.4067/S0366-16442001000300015.

W, Re, NiW and NiRe supported catalyst, on pillared clays (PILC), ultrastable zeolite (USY), active carbon (Carbon) and alumina (Al2O3) were prepared. The active fase and support influence in the reaction of hydrodesulfurization (HDS) of thiophene under atmosferic pressure and T= 400°C have been studied. The catalytic activities increases when the nickel is incorporated 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 are Carbon and Al2O3, no significant change is observed on the catalytic activities. When the used support are PILC and USY the Ni incorporation decreases the catalytic activity. The catalytic activity results are discussed in function of some properties of the support and catalyst, and possible sinergic and antagonic effects that would be generated

Palabras clave : Hydrodesulfurization; PILC; USY; active carbon; HDS of thiophene.
