Functional nanostructured catalysts based on the niobates to the dry methane reforming and ethylene homologation reactions
Catalytic activity and selectivity of niobate-based nanostructured materials were investigated. Dry methane reforming (DMR) and ethylene homologation reaction (EHR) were selected as test reactions. KSr 2Nb5O15, Sr2NaNb5O ...
Textural properties evolution of Ir and Ru supported on alumina catalysts during hydrazine decomposition in satellite thruster
(Elsevier Science BvAmsterdamHolanda, 2003)
Hydrogenation of oleic acid over ruthenium catalysts

Operation of FCC with mixtures of regenerated and deactivated catalyst
(Elsevier Science, 2001-07)
The operation of FCC with mixtures of coked and regenerated catalyst was studied with a riser simulator reactor on two equilibrium catalysts at 550◦C. The coked catalysts maintain an activity level that enables them to be ...
Synthesis and comparison of the activities of a catalyst supported on two silicate materials
The focus of this work is inspecting the synthesis and comparison of the activities of a catalyst supported on two silicate materials in the epoxidation of 1-octene. The two new catalyst materials were characterized by ...
Behavior of PtPb/MgAl2O4 catalysts with different Pb contents and trimetallic PtPbIn catalysts in n-butane dehydrogenation
The behavior of PtPb/MgAl2O4 catalysts in butenes production through the n-butane dehydrogenation has shown that at low contents, the Pb acts as promoter, improving the conversion and selectivity, whereas at higher contents ...
Au/TiO2 supported on ferritic stainless steel monoliths as CO oxidation catalysts
Metallic supported structured catalysts were obtained by washcoating AluchromYHf monoliths with an Au/TiO2 catalyst. The powder catalyst was synthesized by DAE (direct anionic exchange) method. Using this catalyst, a stable ...
Effect of the balance between Co(II) and Co(0) oxidation states on the catalytic activity of cobalt catalysts for Ethanol Steam Reforming
(Elsevier B.V., 2014-06-15)
Changes of the oxidation state of cobalt species during activation under H-2 gas and ethanol steam reforming reaction on Co/Al2O3 were investigated using time-resolved operando Quick-XAS analysis. Prior to activation and ...
