Abstract

L'invention concerne un procédé à lit fluidisé pour améliorer le contact d'une phase gazeuse avec une phase solide. Ce procédé consiste à soumettre un lit constitué de particules composites magnétisables, fluidisables qui contiennent au moins 50 % en volume d'une matière non magnétisable, à un champ magnétique et à faire passer un gaz ascendant à travers le lit à une vitesse superficielle du gaz d'au moins deux fois la vitesse superficielle minimale du gaz requise pour fluidiser le lit en l'absence d'un champ magnétique pour y produire un barbotage d'une façon continue sans entraînement important de solides dans le gaz le lit. Transformation d'hydrocarbures.The invention relates to a fluidized bed process for improving the contact of a gas phase with a solid phase. This process involves subjecting a bed of magnetizable, fluidizable composite particles which contain at least 50% by volume of a non-magnetizable material to a magnetic field and passing an ascending gas through the bed at a superficial gas velocity. at least twice the minimum gas surface velocity required to fluidize the bed in the absence of a magnetic field to continuously bubble therein without significant entrainment of solids in the gas in the bed. Hydrocarbon transformation.
