Title (EN) OLIGOMERISATION OF OLEFINS WITH ZEOLITE CATALYST
(FR) OLIGOMERISATION D'OLEFINES AVEC CATALYSEUR A ZEOLITE
Abstract:
(EN) The conversion and run length for oligomerisation of olefins over a molecular sieve catalyst in a tubular reactor is improved by controlling the peak temperature to not exceed 50 degrees C above the temperature of the temperature control fluid exiting the shell side outlet of the reactor. A tubular reactor containing molecular sieve catalyst is provided with a multipoint thermocouple in at least one tube, and optionally with a bottom design adapted for fast unloading of the molecular sieve catalyst from the tubular reactor.
(FR) Amélioration de conversion et de longueur de cycle pour l'oligomérisation d'oléfines sur tamis moléculaire dans un réacteur tubulaire, par contrôle de température de crête visant à ne pas aller 50° C au-delà de la température du fluide de commande de température qui sort par la sortie côté coque du réacteur. On décrit un réacteur tubulaire qui contient un catalyseur de tamis moléculaire, équipé d'un thermocouple multipoint dans au moins un tube, éventuellement avec une structure de fond permettant le déchargement rapide du catalyseur depuis le réacteur tubulaire.
