Novel Sol-Gel-Based Pt Nanocluster Catalysts for Propane Dehydrogenation

Novel and Effective Copper–Aluminum Propane Dehydrogenation Catalysts

The importance of solid catalysts for converting petroand bulk chemicals is reflected in the sheer magnitude of their market size: catalysts sales topped nine billion dollars in 2009. This large value mirrors also the increasing academic interest in heterogeneous catalysis research. As far as bulk chemicals (such as ethene, propene, and their derivatives) are concerned, there is a strong demand...

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...

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

Propane Dehydrogenation with Better Stability by a Modified Pt-Based Catalyst

The effect of transition metal doping on Pt/Al2O3 catalyst used in propane dehydrogenation reaction at 500 ̊C was studied. The preparation methods investigated were sequential impregnation (Pt followed by the 2 metal or the 2 metal followed by Pt) and co-impregnation. The metal contents of these catalysts were fixed as the weight ratio of Pt per the 2 metal of around 0.075. These catalysts were ...

Metal–Organic Framework Supported Cobalt Catalysts for the Oxidative Dehydrogenation of Propane at Low Temperature

Zr-based metal-organic frameworks (MOFs) have been shown to be excellent catalyst supports in heterogeneous catalysis due to their exceptional stability. Additionally, their crystalline nature affords the opportunity for molecular level characterization of both the support and the catalytically active site, facilitating mechanistic investigations of the catalytic process. We describe herein the...
