Kinetic isotopic effects (KIEs) for oxidative dehydrogenation of propane were measured on 10 wt% V2O5/ZrO2. Normal KIEs were obtained using CH3CH2CH3 and CD3CD2CD3 as reactants for primary dehydrogenation (2.8) and combustion (1.9) of propane and for secondary combustion of propene (2.6), suggesting that in all cases C–H bond dissociation is a kinetically relevant step. CH3CH2CH3 and CH3CD2CH3 ...

supported vanadia catalyst was successfully synthesized using wet impregnation of gamma-alumina to study propane oxidative dehydrogenation (pod). the prepared catalysts were characterized with xrd, bet, and tpr tests. in a broad temperature range (340 to 630°c), effects of vanadia loading (2.7, 5.4, and 9 wt%) and propane to oxygen ratio (3/1 to 1/3) were investigated on propane conversion as w...

The structure of vanadia species supported on zirconia depends on VOx surface density and on the temperature of catalyst oxidation pretreatments. X-ray diffraction and Raman and UV-visible spectroscopies show that supported VOx species form polyvanadate domains of increasing size and ultimately monolayers and clusters as vanadium surface density increases. Initial propene selectivities in oxida...

Propylene is an important raw material and extensively used in the petrochemical industry. There has been a continuously growing demand for propylene in recent years around the world1–3. The majority of propylene is produced as a byproduct from processes such as steam cracking of naphtha and fluid catalytic cracking (FCC)4,5. Additional sources of propylene included dehydrogenation of propane, ...

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...

The influence of the support material of vanadia catalysts on the reaction rate, activation energies, and defect formation enthalpies was investigated for the oxidative dehydrogenation of ethanol and propane. Characterization by infrared absorption–reflection spectroscopy (IRAS), Raman and UV–vis spectroscopy verifies a high dispersion of vanadia for powder and thin-film model catalysts. The su...

This critical review evaluates the state-of-the-art in propane dehydrogenation catalysis using oxidative and non-oxidative methods, with an emphasis on sustainability suitability for process commercialisation.

Abstract This invited Team Profile was created by the Xie and Lin groups, hailing from Key Laboratory of Advanced Carbon‐Based Functional Materials (Fujian Province University) State Photocatalysis on Energy Environment within College Chemistry at Fuzhou University (China). They recently published an article borocarbonitride (BCN) nanosheets derived biomolecule guanine, which proved to be effic...

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.
