Title (EN) BUBBLING FLUIDIZED BED REACTOR WITH CIRCULATION AMONG INTEGRATED BUBBLING ZONES
(FR) RÉACTEUR DE LIT FLUIDISÉ BOUILLONNANT À CIRCULATION PARMI DES ZONES D'ÉBULLITION INTÉGRÉES
Abstract:
(EN) Various aspects provide for a fluidized bed reactor comprising a container having a bed of bed solids and a splashgenerator configured to impart a directed momentum to a portion of the bed solids. A wall may separate the bed solids into first and second reaction zones, and the directed momentum may be used to transfer bed solids from one zone to the other. A return passage may provide for return of the transferred bed solids, providing for circulation between the zones. A compact circulating bubbling fluidized bed may be integrated with a reactor having first and second stages, each with its own fluidization gas and ambient.
(FR) L'invention concerne divers aspects d'un réacteur de lit fluidisé comprenant un récipient comportant un lit de solides de lit et un générateur d'éclaboussures configuré pour imprimer une impulsion dirigée vers une partie des solides de lit. Une paroi peut séparer les solides de lit dans des première et seconde zones de réaction, et le mouvement dirigé peut être utilisé pour transférer les solides de lit d'une zone à l'autre. Un passage de retour peut permettre le retour des solides de lit transférés, assurant une circulation entre les zones. Un lit fluidisé bouillonnant compact à circulation peut être pourvu d'un réacteur ayant des premier et second étages, chacun avec son propre gaz de fluidisation et d'environnement ambiant.
