Oxidative dehydrogenation of 1-butene to butadiene over carbon nanotube catalysts
The applications of carbon nanotubes (CNTs) as catalysts have attracted much interests in catalysis community due to their unique porous microstructure and chemical properties. One of the promising results is the use of CNTs in the oxidative dehydrogenation (ODH) of ethylbenzene to styrene [1,2]. However, only few works were reported on the use of CNTs or other carbonaceous materials to catalyz...
متن کاملOxidative dehydrogenation of 9,10-dihydroanthracene using multi-walled carbon nanotubes
Multi-walled carbon nanotubes (MWCNTs) have been used in the oxidative dehydrogenation of 9,10-dihydroanthracene in an organic solvent (toluene) using molecular oxygen as the oxidant, and in the absence of trace amounts of metals. The process is very selective and almost no anthraquinone is formed. Thermal treatment of the MWCNTs at 2600 °C favors deoxygenation of the support and markedly impro...
متن کاملSurface-modified carbon nanotubes catalyze oxidative dehydrogenation of n-butane.
Butenes and butadiene, which are useful intermediates for the synthesis of polymers and other compounds, are synthesized traditionally by oxidative dehydrogenation (ODH) of n-butane over complex metal oxides. Such catalysts require high O2/butane ratios to maintain the activity, which leads to unwanted product oxidation. We show that carbon nanotubes with modified surface functionality efficien...
متن کاملNi-promoted synthesis of graphitic carbon nanotubes from in situ produced graphitic carbon for dehydrogenation of ethylbenzene.
Graphitic carbon nanotubes (GCNTs) were fabricated from in situ produced graphitic carbon by calcining biomass/melamine/Ni(NO3)2·6H2O. Ni-based hybrids (NiOx@GCNTs) displayed superior catalytic capacity in direct dehydrogenation of ethylbenzene. The specific reaction rate can reach up to 8.1 μmol m(-2) h(-1), and unprecedented stability was obtained over 165 h without any activation process.
متن کاملCatalytic 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 ...
