Title
(EN) PROCESSES AND SYSTEMS FOR USING SILICA PARTICLES IN FLUID BED REACTOR
(FR) PROCÉDÉS ET SYSTÈMES D'UTILISATION DE PARTICULES DE SILICE DANS UN RÉACTEUR À LIT FLUIDISÉ
Abstract
(EN)
The present disclosure relates to fluid bed processes that utilize silica particles as a fluidization aid. The process comprises reacting one or more reactants in a reactor comprising a fluid bed to form a product. The fluid bed comprises a catalyst composition comprising a catalyst and an inert additive composition comprising silica particles from 0.5 wt% to 30 wt%, based on the total weight of the catalyst composition. The silica particles are discrete, inert particles that are mixed with the catalyst in the fluid bed.
(FR)
La présente invention concerne des procédés à lit fluidisé qui utilisent des particules de silice à titre d'agent promoteur de fluidisation. Le procédé consiste à faire réagir un ou plusieurs réactifs dans un réacteur comprenant un lit fluidisé pour former un produit. Le lit fluidisé comprend une composition de catalyseur constituée d'un catalyseur et d'une composition d'additif inerte comprenant des particules de silice de 0,5 % en poids à 30 % en poids, sur la base du poids total de la composition de catalyseur. Les particules de silice sont des particules séparées et inertes qui sont mélangées au catalyseur dans le lit fluidisé.
