Abstract

CUBILLOS, Gloria I.; GARCIA, Jesús A.; DELGADO, Carlos A.  and  GIRALDO, Liliana. DRX STUDY IN CATALYSTS MATERIAL Cu-Ni-SiO2 FOR HYDROGENATION OF SOY OIL. DEVELOPMENT OF CRYSTALLINE STRUCTURE AND CATALYTIC ACTIVITY. Rev.Colomb.Quim. [online]. 2007, vol.36, n.3, pp.323-334. ISSN 0120-2804.

Looking for experimental facts that support the hypothesis of formation of Cu-Ni or Cu-Ni-SiO2 crystals formation hypo- thesis in the syntesis of catalytic materials for soja oil hydrogenation, different mixtures of the metals nitrates with SiO2 (aerosil), were prepared and calcined at 270 oC, then reduced in hydrogen atmosphere at 330 oC. RX Diffraction registers of the prepared materials, Ni-Cu alloys, Ni and Cu pure metals, show that differences in diffraction signal in prepared materials exist with respect to pure metals. The catalytic activity show differences too.

Keywords : Sinergy; Ni-Cu-SiO2 sinergic effects; bimetallic catalyst; soja oil hydrogenation.
