    摘要: 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.
