Title (EN) SYSTEM AND METHOD FOR DEHYDROGENATING ISOBUTANE TO ISOBUTYLENE
(FR) SYSTÈME ET PROCÉDÉ DE DÉSHYDROGÉNATION D'ISOBUTANE EN ISOBUTYLÈNE
Abstract:
(EN) A system and a method for dehydrogenating isobutane to isobutylene are disclosed. The system comprises a fixed bed dehydrogenation reactor. The fixed reactor bed in the fixed bed dehydrogenation reactor includes a catalyst layer, a first material adapted to improve the flow distribution in the fixed reactor bed, a second material adapted to improve the thermal distribution in the fixed reactor bed, and a third material adapted to improve both the flow distribution and the thermal distribution in the fixed reactor bed. The first material covers a top, a bottom, and at least a portion of a side surface of the catalyst layer of the fixed reactor bed. The second material and the third material both are evenly distributed in the catalyst layer.
(FR) La présente invention concerne un système et un procédé pour la déshydrogénation d'isobutane en isobutylène. Le système comporte un réacteur de déshydrogénation à lit fixe. Le lit fixe de réacteur dans le réacteur de déshydrogénation à lit fixe comprend une couche de catalyseur, un premier matériau conçu pour améliorer la distribution de l'écoulement dans le lit fixe de réacteur, un second matériau conçu pour améliorer la distribution thermique dans le lit fixe de réacteur, et un troisième matériau conçu pour améliorer à la fois la distribution de l'écoulement et la distribution thermique dans le lit fixe de réacteur. Le premier matériau recouvre une surface supérieure, une surface inférieure et au moins une partie d'une surface latérale de la couche de catalyseur du lit fixe de réacteur. Le deuxième matériau et le troisième matériau sont tous les deux répartis uniformément dans la couche de catalyseur.
