Title: Performance of noble metal-Mo/γ-Al2O3 catalysts: Effect of preparation parameters
Abstract: The catalytic performance of bimetallic catalysts NM-Mo (NM=Pt, Pd, Ru) supported on γ-alumina was evaluated in simultaneous hydrodresulfurization (HDS) and hydrogenation (HYD) reactions. Nature of noble metal, calcination temperature after noble metal impregnation, activating mixture composition and the effect of the impregnation of noble metal on MoS2/γ-Al2O3 were the parameters studied. Results show that the noble metal nature and impregnation of noble metal on MoS2/γ-Al2O3 are the principal factors that influence the catalytic performance. PtMo/γ-Al2O3 and RuMo/γ-Al2O3 display a high synergetic effect. Catalysts prepared impregnating noble metal on MoS2/γ-Al2O3 present higher activities than the corresponding ones prepared impregnating noble metal on MoO3/γ-Al2O3. Calcination temperature after noble metal impregnation does not have an important influence on catalytic activity.
