Fluidized bed reactor for the implementation of a reaction in gas phase

Fluidized bed reactor (1) for the implementation of a reaction in gas phase, crossing unamezcla gaseous reaction a heterogeneous catalyst in the form of particles which form a fluidized bed, deabajo upwards and arranged inserts being (3 ) in the fluidized bed, characterized in that loselementos insertion (3) divide the fluidized bed into a plurality of cells arranged horizontally, akin to a plurality of cells (4) arranged vertically in the fluidized bed reactor (1), with paredescelulares are gas permeable and have openings which ensure an index exchange catalizadorheterogeneo particulate vertically in the range of 1 to 100 liters / hour per liter of volume dereactor.
