Sulfuros másicos obtenidos a partir de óxidos mixtos de alta área específica como catalizadores de hidrotratamiento

ABSTRACT: Several bimetallic Ni-Mo, Co-Mo and Co-W materials were prepared by co-precipitation and a Ni-W material through hydrothermal synthesis. The characterization by X-ray diffraction (XRD) of molybdates confirmed the formation of layered fy phase, while the tungstates showed both fy semicrysta...
