Propane Dehydrogenation over Alumina-Supported Iron/Phosphorus Catalysts: Structural Evolution of Iron Species Leading to High Activity and Propylene Selectivity

Dehydrogenation of Propane to Propylene Over Pt-Sn/Al2O3 Catalysts: The influence of operating conditions on product selectivity

Dehydrogenation of Propane to Propylene over Supported Model Ni–Au Catalysts

Hydrogenolysis and dehydrogenation of propane were studied over model nickel–gold catalysts. The supported model Ni–Au catalysts were prepared by depositing Ni and Au onto a planar silica film. Infrared reflection absorption spectroscopic data showed that isolated Ni sites appeared and became dominant on the surface with the addition of Au to Ni. For the conversion of propane in the presence of...

Effects of additives on the activity and selectivity of supported vanadia catalysts for the oxidative dehydrogenation of propane

The activity and selectivity of aluminaand magnesia-supported vanadia for propane oxidative dehydrogenation can be enhanced by can be enhanced by interactions of vanadia with molydena for the alumina-supported catalyst and by phosphorous doping for the magnesia-supported catalyst.

Silica-Supported Au–Ni Catalysts for the Dehydrogenation of Propane

Inspired by previous studies on model systems, a series of silica-supported Au–Ni catalysts were prepared and tested for the conversion of propane in the presence of hydrogen. The Au–Ni/SiO2 catalysts were prepared by successive impregnation, i.e. Ni was deposited first followed by Au. TEM/EDX results confirmed the presence of bimetallic Au–Ni nanoparticles. The dehydrogenation of propane to pr...

Tunability of Propane Conversion over Alumina Supported Pt and Rh Catalysts

Propane conversion over alumina supported Pt and Rh (1 wt% metals loading) was examined under fuel rich conditions (C3H8:O2:He = 1:2.25:9) over the temperature range 450–650 C. Morphological characteristics of the catalyst materials were varied by calcining at selected temperatures between 500 and 1,200 C. X-ray diffraction and BET analysis showed the treatment generated catalyts metals with pa...
