Ethane and propane dehydrogenation over PtIr/Mg(Al)O

Catalytic oxidative dehydrogenation of propane over Mg–V/Mo oxides

Fifteen distinct MgO–V2O5, MgO–MoO3, MgO–V2O5–MoO3, and V2O5–MoO3 compositions were prepared using sol–gel chemistry and their selectivities and conversions for propane oxidative dehydrogenation (ODH) to propylene were measured. The vanadates were more active than the molybdates at lower temperatures; however, the molybdates exhibited higher selectivities at similar conversions. An increase in ...

Propane oxidative dehydrogenation over vanadium oxide nanostructures supported on porous graphene prepared by hydrothermal method

In this study at first, in laboratory, three types of vanadium oxide were produced by using porous graphene and amine framework in hydrothermal method nanostructures such as: vanadium oxide - octadecyl amine - graphene, vanadium oxide - dodecyl amine - graphene and vanadium oxide – aniline - graphene (V-ODA-G، V-DDA-G، V-A-G). Then their structures and functions in propane dehydrogenation react...

Reforming and oxidative dehydrogenation of ethane with CO2 as a soft oxidant over bimetallic catalysts

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...

Oxidative Dehydrogenation of Ethane to Ethylene with CO2 over Fe−Cr/ZrO2 Catalysts

The catalytic performance of Fe-Cr/ZrO2 catalysts, prepared by two different methodsscoprecipitation and coprecipitation-impregnation were examined in oxidative dehydrogenation of ethane to ethylene using CO2 as an oxidant. Thermogravimetric analysis and physicochemical characterization such as XPS, XRD, and BET were performed to explore the correlation of catalytic performance with physicochem...
