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. ...
Hydrogen-selective natural mordenite in a membrane reactor for ethane dehydrogenation
(Elsevier, 2014-02)
Lab-scale ethane dehydrogenation experiments with natural mordenite disks in a membrane reactor showed an increase in ethane conversion and ethylene yield compared to their equilibrium values. Experiments performed with ...
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 ...
Liquid transportation fuels from biomass-derived oxygenates: Gas-phase 2-hexanol upgrading on Cu-based mixed oxides
(Elsevier Science, 2015-01)
The gas-phase upgrading of 2-hexanol, a model molecule of the primary conversion of sugars, toward higher molecular weight compounds of application as liquid transportation fuels was investigated on Cu-MI-MII mixed oxides ...
Deshidrogenación oxidativa de isobutano
(Universidad Nacional de Colombia - Facultad de Ingeniería, 2001)
La deshidrogenación oxidativa de alcanos es una reacción interesante debido en gran parte a la diferencia de precio entre los aleanos livianos, y sus correspondientes olefinas, su disponibilidad, y el hecho de que son ...
Crystal phase dependent metal-support interactions in Pt/SO42--ZrO2 catalysts for hydroconversion of n-alkanes
(Elsevier Science, 2004-07)
In order to elucidate the influence of the crystal structure of zirconia on the properties of the metallic and acid function of Pt/SO42−-ZrO2, catalysts with different zirconia crystal phases were synthesized, fully ...
Hydrogen adsorption on β-Ga2O3(1 0 0) surface containing oxygen vacancies
(Elsevier Science, 2005-12)
The understanding of hydrogen (H) adsorption on gallia is an important step in the design of molecular sensors and alkane dehydrogenation–aromatization catalysts. We have simulated the (100) surface of b-Ga2O3, which is ...
Insights on hydride formation over cerium-gallium mixed oxides: a mechanistic study for efficient H2 dissociation
(Elsevier, 2017-01)
A four-step reaction mechanism is proposed for the H2 dissociation over pure ceria and Gallium promoted mixed oxide materials, in a combined experimental and computational investigation. Two samples of cerium-gallium mixed ...
