Síntesis de Catalizadores Co-Mo en Varios Soportes.

Abstract

Heterogeneous catalysis is the most applied industrially, it is based on the use of metals, oxides or salts dispersed on the internal surface of a porous support, hydroprocessing in refineries use catalysts such as Molybdenum and Cobalt metal sulfides. The objective of the present work is to synthesize and characterize activated carbon catalysts with Cobalt and Molybdenum, for which, 3 methods of impregnation of the active phase were proposed, 2 direct methods and one successive. By means of a morphological and quantitative analysis of the active phase, successive impregnation was selected to avoid agglomerations and support preference. The FTIR spectrum revealed differences between the activated carbon without impregnation and after the addition of Co and Mo, while the diffractogram of the catalyst confirmed the presence of the MoO3 phase necessary to promote MoS2. The surface area of the supported catalyst obtained by BET analysis decreased by 5.55 %, which represents a good applicability for the development of reactions on the surface.
