Cr–MnOx mixed-oxide catalysts for selective catalytic reduction of NOx with NH3 at low temperature
TL;DR: In this paper, the authors showed that a crystalline phase of CrMn1.5O4 was present in the Cr-MnOx catalysts, which contained the active species and showed the presence of Mn2+, Mn3+, Mn4+ and Cr2+, Cr3+, Cr5+ oxidation states.
Journal ArticleDOI
Kinetics of Oxidative Dehydrogenation of C2‐C3 Alkanes on Oxide Catalysts
TL;DR: A survey of the main facts and concepts appeared in the last years on kinetics of oxidative dehydrogenation (ODH) of ethane, propane, butane and isobutane is given in this article.
Journal ArticleDOI
Aerobic Oxidations of Light Alkanes over Solid Metal Oxide Catalysts
TL;DR: This review outlines the properties of supported metal oxides, mixed-metal oxides and zeolites and detail their most common applications as catalysts for partial oxidations of light alkanes to form olefins and oxygenates and identifies common themes in reaction mechanisms and research strategies.

Behavior of active sites on Cr-MCM-41 catalysts during the dehydrogenation of propane with CO2
Katsuomi Takehira,Yoshihiko Ohishi,Tetsuya Shishido,Tomonori Kawabata,Ken Takaki,Qinghong Zhang,Ye Wang +6 more
TL;DR: In this paper, the mechanism of catalyst deactivation and regeneration was discussed based on the structure-catalytic property relationships. And the authors concluded that during the reaction propane is dehydrogenated to propene by Cr(IV)O4 tetrahedra, which is simultaneously reduced to Cr(III)O6 octahedra.
Journal ArticleDOI
Dehydrogenation of ethane with carbon dioxide over supported chromium oxide catalysts
TL;DR: In this article, the effect of support on the catalytic activity of Cr2O3/SiO2 catalysts was investigated in the oxidative dehydrogenation of ethane into ethylene by carbon dioxide.

Oxidations carried out by means of vanadium oxide catalysts
P. Mars,D. W. van Krevelen +1 more
TL;DR: In this paper, it was shown that the partial pressures of the reacting substances appeared to influence the reaction rate, and a formula depicting this influence was derived, which may be interpreted by assuming two successive reactions, namely the reaction between the aromatic and the oxygen on the surface, and the re-oxidation of the partly reduced surface by means of oxygen.

Quantitative Chemical Analysis by ESCA
TL;DR: In this paper, the electron mean free path for inelastic scattering as a function of energy for all elemental solids (with the exception of the rare earths and the actinides) and formulae for the calculation of the mean free paths for compounds were given.
