REACTION DEVICE HAVING A NUMBER OF MOVING BED ZONES WITH SUPPLEMENTING IN EACH REGENERATED OR FRESH CATALYST ZONE

摘要

present invention is highly endothermic or exothermic reaction zone for having done that staged reactor relates to . The apparatus , to supplement a fresh catalyst or a regenerated catalyst at the inlet of each reaction zone to reduce the catalyst activity difference between these zones , and provides the integrated heat exchanger . Further, the present invention relates to a chemical conversion process for preparing a diesel fraction using the device of the present application for the oligomerization reaction of the exothermic or endothermic gas phase and / or liquid phase reaction , in particular C2 to C12 fraction
