The oxidative dehydrogenation of propane with CO2 (CO2-ODP) is a promising technology for the efficient production propene in tandem reduction to CO. However, rational design high-performance catalysts this green process still challenged by limited understanding nature active sites and reaction mechanism. In work, effects SnO2 promoter on Pt/CeO2 activity selectivity CO2-ODP are elucidated thro...

With the surge of shale gas, propane dehydrogenation becomes increasingly important to synthesize propylene. Herein, a new type ordered PtSnZn intermetallic clusters (∼0.9 nm) supported on Al2O3 was synthesized by stepwise approach including electrostatic adsorption and temperature-programmed reduction. The structure results from kinetically controlled process, Pt atoms in are well isolated Sn ...

Divinylbenzene (DVB) is produced by catalytic dehydrogenation of DEB at high temperature and atmospheric pressure. Ethylvinylbenzene (EVB) is produced as a useful chemical during dehydrogenation of DEB. Also some other liquid and gaseous by products is produced during dehydrogenation. A set-up has been developed to conduct the DEB dehydrogenation reactions experiments to prepare DVB at differen...

Abstract One class of particularly active catalysts for the Propane Dehydrogenation (PDH) reaction are well-defined M(III) sites on amorphous SiO 2 . In present work, we focus evaluating catalytic trends PDH four single-sites (Cr, Mo, Ga and In) a realistic model using density functional theory-based calculations energetic span model. We considered pathway spanned by three steps taking place se...
