Sulfide molybdenum catalysts for water–gas shift reaction: Influence of the kind of promoters and supports to generate MoS2
چکیده انگلیسی


• The water–gas shift activity of the catalyst concluding Mo was highest by adding Ni.
• The reducibility of MoO3 is improved by adding a large electronegativity component.
• The generation of MoS2 which is active site is enhanced by adding Ni.
• MoS2 generation was most enhanced with the Ni/Mo/TiO2 catalyst.

In the water–gas shift (WGS) catalyst which MoS2 is an active site, the shift activity was examined for catalysts which seven sort components with different electronegativity were added to Mo/Al2O3. The shift activity was highest with the catalyst by adding Ni, which has the largest electronegativity. The results suggest that the reducibility of MoO3 is improved by adding a large electronegativity component, and as a result, the generation of MoS2 is enhanced in the pretreatment process. Furthermore, as a result of searching for the optimal composition including the support, MoS2 generation was most enhanced with the Ni/Mo/TiO2 catalyst, and shift activity was also maximized.
