Abstract
The invention relates to a process and an apparatus for the production of aromatic hydrocarbons from an aliphatic hydrocarbon charge with 2 to 12 carbon atoms. The process comprises a stage of contacting a charge of at least one aliphatic hydrocarbon with 2 to 12 carbon atoms and a zeolitic catalyst composition optionally containing at least one metal, in a reaction zone (40) containing reaction tubes (3), said reaction zone being heated by at least partial immersion in an enclosure (1) containing a fluidized particle bed (13), characterized in that said particle bed is at least partly heated by a heat supply (19,23) resulting from the injection of hot gases produced in a zone outside said enclosure and introduced into the fluidized bed under conditions such that the reaction temperature is 400.degree. to 600.degree. C. Application to the production of benzene, toluene and xylenes.
