Reactor having a plurality of fixed bed or mobile bed zones with integrated heat exchanger

摘要

A multi-stage axial flow reactor for effecting strongly enothermic or exothermic reactions comprises a narrowed-down section between an upper and lower reaction zone; and in this section is placed a thermal exchanger for intermediate re-heating or cooling of effluents from the upper zone. The reactor is aligned along a verical axis and comprises several zones. It is adapted to an axial circulation of a reaction fluid and comprises means of introduction an evacuation of the reaction fluid, and introduction and evacuation of catalyst. The upper zone is filled with a granular catalyst and is linked via a narrow section to a lower zone also containing catalyst.The reaction fluid is introduced at the lower part of the reactor and the reaction products evacuated at the upper part. An independent claim is also included for a chemical converion process.
