Study of a multitubular fixed-bed reactor for ethylene production via ethane oxidative dehydrogenation
(Elsevier Science SA, 2008-12)
In the present contribution, a theoretical study of a multitubular fixed bed reactor for the ethane to ethylene oxidative dehydrogenation reaction over a highly active and selective Ni-Nb-O mixed oxide catalyst is presented. ...
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.% ...
New Formulations of Ni-Containing Ceramic Papers to Enhance the Catalytic Performance for the Oxidative Dehydrogenation of Ethane
(American Chemical Society, 2014-10)
Ceramic papers composed of silica–alumina fibers structured using colloidal suspensions as binders constitute interesting materials to be used as flexible supports of catalytic materials. The deposition of Ni as the active ...
Preparation of NiNbO/AISI-430 ferritic stainless steel monoliths for catalytic applications
(American Chemical Society, 2014-06)
AISI 430 ferritic stainless steel was used as a substrate to make catalytic monolithic structures. To increase the surface roughness of the substrate, the steel was oxidized at temperatures in the range of 900–940 °C and ...
Flexible NiZr-based structured catalysts for ethylene production through ODH of ethane: Catalytic performance enhancement
(Elsevier Science, 2016-09)
Flexible structured catalysts based on Ni and Zr deposited on a ceramic paper made of SiO2-Al2O3andZrO2fibers showed to be active and selective for the Oxidative Dehydrogenation of Ethane. Zirconiumpromoter strongly ...
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 ...
Novel Ni-Ce-Zr/Al2O3 Cellular Structure for the Oxidative Dehydrogenation of Ethane
(MDPI, 2017-11)
A novel gamma-alumina-supported Ni-Ce-Zr catalyst with cellular structure was developed for oxidative dehydrogenation of ethane (ODHE). First, powdered samples were synthesized to study the effect of both the total metal ...
Alumina-supported nickel onto cordierite monoliths for ethane oxydehydrogenation: Coating strategies and their effect on the catalytic behavior
(American Chemical Society, 2016-01)
Different strategies for the generation of Ni (15 wt.%)/Al2O3 catalytic coatings onto cordierite monoliths applied to the oxidative dehydrogenation of ethane (ODHE) were investigated. Strategy 1 involved the deposition of ...
NiNbO Catalyst Deposited on Anodized Aluminum Monoliths for the Oxidative Dehydrogenation of Ethane
(John Wiley & Sons Inc, 2017-01-27)
Aluminum monoliths were used as substrates to prepare structured catalysts. A rough alumina layer was generated on the surface of the substrates by anodizing followed by hydrothermal treatments. The dip-coating technique ...
