Abstract[English]
The disclosure relates to systems and methods to alter the ethylene and/or acetic acid selectivity in the catalytic oxidative dehydrogenation of ethane with a catalyst that includes molybdenum (Mo), vanadium (V), and bismuth (Bi), using reactor space velocity.[French]
La divulgation concerne des systèmes et des procédés pour modifier la sélectivité en éthylène et/ou en acide acétique dans la déshydrogénation oxydative catalytique de l'éthane avec un catalyseur comprenant du molybdène (Mo), du vanadium (V) et du bismuth (Bi), en utilisant la vitesse spatiale du réacteur.
