Several reactor configurations have been tested for catalytic propane dehydrogenation employing Pt-Sn/MgAl2O4 as a catalyst. Pd-Ag alloy membranes coupled to the multifunctional Two-Zone Fluidized Bed Reactor (TZFBR) provide an improvement in propane conversion by hydrogen removal from the reaction bed through the inorganic membrane in addition to in situ catalyst regeneration. Twofold process ...

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...

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.

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...

Boron nitride and related boron-containing materials have recently been suggested as very promising catalysts in the oxidative dehydrogenation of propane. The high selectivity toward propylene at c...

The gas phase reaction of V4O10 with propane is studied by infrared photodissociation spectroscopy combined with density functional calculations. Mass-selected V4O10 clusters react with propane under thermalized, multiple collision conditions in a buffer gas filled ion trap at 100 K. Two main reaction paths are identified: (i) oxidative dehydrogenation forming V4O8(OH)2 + propene and (ii) direc...

A repetitive control technique which is based on a time-varying stochastic state space model obtained by cycle-to-cycle linearization of a nonlinear fundamental process model around the operation trajectories in the previous cycle is introduced. The control technique was applied to two repetitive chemical processes: simulated moving bed, a continuous chromatograph separation process, and CATOFI...

The mechanistic connections among propane oxidative dehydrogenation (ODH) rates, H2 reduction rates, and the electronic transitions responsible for the absorption edge in the electronic spectra of dispersed metal oxides were explored for VOx, MoOx, WOx, and NbOx samples consisting predominately of two-dimensional oxide domains supported on Al2O3, ZrO2, and MgO. For a given active oxide, propane...
