Oxidative dehydrogenation of ethane to ethylene in a membrane reactor: A theoretical study
(Elsevier Science, 2010-11)
This contribution presents a theoretical study of a multitubular packed-bed membrane reactor for the ethane to ethylene oxidative dehydrogenation reaction over a highly active and selective Ni-Nb-O mixed oxide catalyst. ...
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 ...
High catalytic activity at low temperature in oxidative dehydrogenation of propane with Cr–Al pillared clay
(Elsevier Science Sa, 2013-10)
A montmorillonite was pillared separately with chromium and aluminum polyoxocations (Cr–C and Al–C respectively) and also with an equimolar mixture of both polioxocations (Al–Cr–C). The resulting solids were characterized ...
Characterization and performance for propane oxidative dehydrogenation of Li-modified MoO3/Al2O3 catalysts
(Elsevier Science, 2003-09)
Oxidative dehydrogenation of propane has been studied on Mo/γ-Al 2O3 catalysts with 13wt.% of MoO3 and promoted with Li. The changes induced on catalysts when the support is doped with different amounts of Li (from 0.3 to ...
Sol-gel synthesis of V2O5-SiO2 catalyst in the oxidative dehydrogenation of n-butane
(Elsevier Science, 2006-09)
The sol-gel method was used to prepare V-SiO2 catalyst by hydrolysis of vanadium acetylacetonate and silicon alkoxide. Structural changes in the vanadium species upon heat treatment at various temperatures were studied by ...
Oxidative dehydrogenation of propane and n-butane over alumina supported vanadium catalysts
(Planta Piloto de Ingeniería Química, 2004-12)
Structural properties of vanadium dispersed species on γ-A1203 are investigated with the scope to detect changes related with V loading in the oxidative dehydrogenation (ODH) of propane and nbutane. XPS, FTIR, and FTIR of ...
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 ...
Gas-phase conversion of 1,3-butanediol on single acid-base and Cu-promoted oxides
(Elsevier Science, 2013-09)
The gas-phase conversion of 1,3-diols was studied on catalysts containing different active sites and using 1,3-butanediol as a model molecule. Transformation of the diol primary and/or secondary OH groups by dehydration ...
