Interaction of carbon dioxide with methane on oxide catalysts

On the initial deactivation of MnxOy–Al2O3 sorbents for high temperature removal of H2S from producer gas

“…Besides their use as sorbents or heterogeneous catalysts, the oxides are commercially used in the production of drybatteries cathodes and in the steel production. The catalytic applications of Mn oxides alone or in a combination with other elements that can be of particular interest in the area of the producer gas upgrade and Fuel Processing Technology 133 (2015) [183][184][185][186][187][188][189][190][191][192][193][194] utilization are the Water Gas Shift Reaction, Methane Reforming and Fischer-Tropsch synthesis [10][11][12].…”

XAFS study on Mn-Ni/Al2O3 catalyst for carbon dioxide reforming of methane

“…In addition, there could be other roles of manganese oxide species deposited on the nickel surface. It has been shown that manganese oxide could form a surface carbonate species which reacts with carbon deposited on the surface by methane decomposition (Krylov et al, 1998). Thus, manganese oxide islands in Mn-Ni/Al 2 O 3 catalyst may enrich the surface with a reactive carbonate species, which removes the coke deposited on the catalyst surface.…”

First Row Transition Metal Oxide Based Catalysts for the In-situ Reactions of Methanation and Desulfurization in the Removal of Sour Gases from Simulated Natural Gas

“…Such requirements are met with some transition metal oxides and apparently some Lanthanide oxides. Their acid and redox properties may be changed by adding other oxides (Krylov et al, 1998). Investigation done by Wang et al (2007) found that the adsorption strength of CO 2 is controlled by the Lewis basicity of a catalyst, d-band center of the metal surface, charge transfer from the metal surfaces to the chemisorbed CO 2 .…”
