The present invention relates to a method for carrying out endothermic reactions, comprising the method steps: a) external heating of at least two reaction tubes (5), wherein the reaction tubes (5) are arranged vertically in a heating chamber (3) and each of the reaction tubes (5) is at least partially filled with a fluidizable material, b) introduction of at least one gaseous reactant (E) into the reaction tubes (5), c) forming a fluidized layer (7) in the reaction tubes (5), d) carrying out the endothermic reaction in the reaction tubes (5) at a first temperature (T1) and a first pressure (P1), the reaction volume being distributed between at least two of the reaction tubes (5), and e) draining the reaction product (P) from the reaction tubes (5). The present invention also relates to a device (1) for carrying out endothermic reactions, which comprises at least one heating chamber (3), at least two reaction tubes (5), wherein the reaction tubes (5) are arranged vertically in the heating chamber (3) and each of the reaction tubes (5) is at least partially filled with a fluidizable material, for each reaction tube (5) at least one inflow point (9) for gaseous reactants (E), for each reaction tube (5) at least one outflow point (11) for reaction products (P), and at least one heating device (13) for externally heating the reaction tubes (5). The present invention also relates to the use of the device (1) according to the invention for the non-oxidative dehydroaromatization of C1 to C4 aliphates. |
