摘要： The invention concerns a process for converting hydrocarbons using at least one globally endothermic chemical reaction, in which a hydrocarbon feed successively traverses at least two reaction zones each containing at least one solid catalyst and comprising between said reaction zones an intermediate step, in a non catalytic zone, for reheating the stream (ST) from the first of the two reaction zones prior to its introduction into said second reaction zone, and in which said reheating is carried out in a heat exchanger, with heat transfer essentially by convection using a thermal fluid TF with a coking sensitivity index CS that is less than that of the stream ST, the difference in temperature ΔT between the temperature of the fluid TF at the inlet to the exchanger and the temperature of the stream ST at the heat exchanger outlet being less than 250° C. The invention also concerns the use of said process for converting hydrocarbons and a unit for carrying out the process.

摘要： An elongate reaction vessel and process includes at least two stages in the vertical direction in which an endothermic or exothermic catalytic reaction is carried out and comprises: a catalytic reaction zone (12a, 12b) per stage (6, 7); introducing (2) a reaction fluid to a stage adapted for transverse motion of the fluid across the whole vertical extent of the reaction zone; introducing and extracting the catalyst; a heat exchanger (5a) for reaction fluids located inside the vessel between two successive reaction zones; means (6) for transporting reaction fluids from one stage to another preferably connected to the exchanger of the stage under consideration and to the inlet for reaction fluids of the subsequent stage; and means for recovering reaction fluids downstream of the last stage. The temperature variation in each zone and the temperature level are respectively adjusted by the thickness of each zone and by heat exchange.
