PROCEDURE AND DEVICE FOR REGULATING OR CONTROLLING THE THERMAL LEVEL OF A POWDER SOLID, INCLUDING A HEAT EXCHANGER FOR COMPARTMENTS IN FLUIDIZED OR MOBILE BED.

摘要

A PROCEDURE AND A THERMAL REGULATION DEVICE FOR FLUIDIZED BEDS OR MOBILE CATALYST ARE DESCRIBED, THE DEVICE CONTAINING A FLUIDIZED OR MOBILE BED HEAT EXCHANGER. ACCORDING TO THE INVENTION, A SOLID POWDER IS CIRCULATED ESSENTIALLY FROM THE BASIS OF A CABINET (1) IN A HEAT EXCHANGER (6) WHICH CONSISTS OF AN INTERNAL SEPARATION MEMBRANE (22) DEFINING TWO COMPARTMENTS (23, 24) EXTENDED AND CONTIGUES THAT COMMUNICATE THROUGH THEIR LOWER PART. IN THE COMPARTMENT WHERE THE POWDER SOLID IS SPILLED, THE FLUIDIZATION SPEED IS INCLUDED BETWEEN 0.1 CM AND 2 M / S, WHILE IN THE COMPARTMENT WHERE THE POWDER SOLID IS INCREASED IN THE HEAT CHANGER (6) , THE FLUIDIZATION SPEED IS INCLUDED BETWEEN 0.1 AND 6 M / S. APPLICATION ESPECIALLY TO REFINING REACTIONS (CATALYTIC REFORMING FOR EXAMPLE) OR TO THE REGENERATION OF A CATALYTIC CRACKER CATALYST IN A FLUIDIZED BED OF AN OIL LOAD, OR TO THE COMBUSTION OF COAL.
