DEVICE AND METHOD FOR GAS-SOLID SEPARATION USING CATALYTIC CRACKING IN A FLUIDIZED BED WITH SIDE OPENINGS

摘要

The invention relates to a device and a method for separating and stripping a gaseous mixture and solid particles, comprising a plurality of separation chambers (12) and pre-stripping chambers (13) distributed around a central reactor (14), wherein each pre-stripping chamber (13) has a peripheral wall; a lower outlet opening (24) of solid particles, which is adapted to communicate with the stripping chamber (23); an upper outlet opening (31) of the gaseous mixture and stripping gas, which is adapted to communicate with a second separation stage; and a lateral inlet opening (28) of the stripping gas.
