With the dehydrogenation reaction being favoured by high temperatures and low partial pressures, all commercially available technologies keep the process temperature at or below approximately 650°C, because higher temperatures would lead to a significant increase in side reactions and therefore a decrease...
Results support a redox reaction mechanism in which propane and intermediate products react with lattice oxygen, reducing the catalyst surface, which is reoxidized by gas-phase O 2 . Partial reduction of the catalyst occurs during the start-up to a steady state. Successive pulsing with C 3 H ...
The exothermic oxidative dehydrogenation of propane reaction to generate propene has the potential to be a game-changing technology in the chemical industry. However, even after decades of research, selectivity to propene remains too low to be commercially attractive because of overoxidation of propene...
