ENDOTHERMIC REACTION UNIT AND STEAM REFORMING DEVICE COMPRISING THIS REACTION UNIT

摘要

The present invention relates to an endothermic reaction unit to be used, preferably but not exclusively, in catalytic reforming processes of hydrocarbons, such as a methane steam reforming process. The reaction unit according to the invention comprises a first combustion chamber made of metal material, inside which a first combustion stage is produced and a second combustion chamber defining a second combustion stage. The first combustion chamber is housed at least partly inside the second combustion chamber. The reaction unit comprises one or more reaction elements each comprising a housing body through which a reaction mixture is destined to pass. These reaction elements are housed at least partly inside the second combustion chamber and are thermally connected to the first combustion chamber so that at least part of the heat generated inside the first combustion chamber is transferred by conduction to these reaction elements.
