Dehydrogenation and oxidative dehydrogenation of alcohols on silica supported chromium catalysts
(Planta Piloto de Ingeniería Química, 2002-03)
The catalytic activity of Cr/SiO2 (0.43 to 2.8% chromium by weight), prepared by the ion exchange method, for the dehydrogenation (573 K to 673 K)and oxidative dehydrogenation (503 K to 558 K) of alcohols has been investigated. ...
Catalytic performance and stability of isomorphic molybdates used for the oxidative dehydrogenation of propane
(Springer, 2005-05)
Co and Mn molybdates were used for this reaction. After use, their structure remained the same. However, only the Co molybdate maintained the surface area and the catalytic properties after 48 h on stream.
Cu, Mn and Co molybdates derived from novel precursors catalyze the oxidative dehydrogenation of propane
(Elsevier Science, 2005-10)
The activity of various transition metal molybdates in the oxidative dehydrogenation of propane was tested. A series of nine molybdates of Zn, Cu, Co, Fe and Mn were synthesized by either a hydrothermal or a precursor ...
Effect of Boron Promotion on Coke Formation during Propane Dehydrogenation over Pt/γ-Al 2 O 3 Catalysts
(American Chemical Society, 2020-04)
The effect of boron promotion on the performance of 3 wt.% Pt/γ-Al2O3 catalysts during propane dehydrogenation was investigated. A series of boron-promoted Pt/XB-γ-Al2O3 catalysts were synthesized, tested, and characterized. ...
Comparison of Ni and Ni-Ce/Al2O3 catalysts in granulated and structured forms: Their possible use in the oxidative dehydrogenation of ethane reaction
(Elsevier, 2014-03)
Ni and Ni-Ce/Alumina catalysts in structured form were prepared, characterized by different techniques and tested in the oxidative dehydrogenation of ethane (ODE). In order to gain further insight into active species, ...
Ni-Nb mixed oxides: One-pot synthesis and catalytic activity for oxidative dehydrogenation of ethane
(Elsevier Science, 2014-06-20)
Ni–Nb mixed oxides were prepared by two methods, conventional evaporation method and combustion synthesis. With the latter technique, the mixed oxide can be quickly prepared from an aqueous solution of metal precursors ...
The Influence of the amount and impregnation sequence of potassium on the catalytic performance of Vox/Al2O3 for the non-oxidative dehydrogenation of n-butane
(Sociedade Brasileira de Química, 2012-06)
The non-oxidative dehydrogenation of n-butane was studied over potassium-promoted supported vanadium alumina catalysts (at 823 K under atmosphere pressure) to explore the Influence of the amount and the order of potassium ...
VOx/c-Al2O3 catalyst for oxidative dehydrogenation of ethane to ethylene: desorption kinetics and catalytic activity
(Elsevier Science, 2013-01)
This study reports ethane oxidative dehydrogenation (ODH) using lattice oxygen. Ethane ODH is studied under an oxygen-free atmosphere employing a 10 wt.% VOx supported on c-Al2O3. TPR and TPO show that the prepared 10 wt.% ...
Effect of CO2 in the oxidative dehydrogenation reaction of propane over Cr/ZrO2 catalysts
(Elsevier B.V., 2018-05-25)
Investigation was made on the effect of chromium content, and method of hydrothermal preparation of Cr/ZrO2 catalysts on their catalytic properties for CO2 oxidative dehydrogenation of propane (ODP). The catalysts were ...
