Catalyst reaction vessel

Claim 1

AN APPARTUS OF THE CHARACTER DESCRIBED INCLUDING A VESSEL ADAPTED TO CONTAIN A FLUIDIZED BED OF SOLID PARTICLES AND FOR CONTACTING GASEOUS FLUID AND FINELY DIVIDED SOLID PARTICLES AND HAVING A TOP OUTLET FOR GASEOUS FLUID AND A BOTTOM OUTLET FOR SOLID PARTICLES, AN INLET CHAMBER IN THE BOTTOM PORTION OF SAID VESSEL FOR THE SUPPLY OF GASEOUS FLUID AND FINELY DIVIDED SOLIDS TO SAID VESSEL, A HORIZONTALLY ARRANGED PERFORATED MEMBER AT THE UPPER PORTION OF SAID INLET CHAMBER, SAID PERFORATED MEMBER BEING CONCENTRIC WITH SAID VESSEL, A AND OF SMALLER DIAMETER, A VERTICALLY DISPOSED SLEEVE EXTENDING ABOVE SAID PERFORATED MEMBER AND SECURED TO THE PERIPHERY THEREOF, SAID SLEEVE EXTENDING A SUBSTANTIAL DISTANCE UPWARDLY IN SAID VESSEL ABOVE THE MAXIMUM LEVEL OF THE DENSE FLUIDIZED BED OF SOLID PARTICLES ADAPTED TO BE MAINTAINED IN SAID VESSEL AND BEING SPACED FROM THE INNER WALL OF SAID VESSEL TO PROVIDE AN ANNULAR SPACE FOR THE WITHDRAWAL OF SOLIDS, MULTIPLICITY OF RADIAL BAFFLES OF SUBSATNAIALLY THE SAME HEIGHT AS SAID SLEEVE AND ARRANGED BETWEEN THE OUTER WALL OF SAID SLEEVE AND THE INNER WALL OF SAID VESSEL FOR DIVIDING SAID ANNULAR SPACE INTO A MULTIPLICITY OF ELONGATED NARROW PARALLEL CELLS, SAID VERTICAL SLEEVE BEING PROVIDED WITH A MULTIPLICITY OF INLET PORTS ARRANGED ENTIRELY AROUND SAID VERTICAL SLEEVE AND ABOVE SAID HORIZONTALLY ARRANGED PERFORATED MEMBER BUT BELOW THE MINIMUM LEVEL OF THE DENSE FLUIDIZED BED OF SOLIDS ADAPTED TO BE MAINTAINED IN SAID VESSEL FOR THE DISCHARGE OF SOLIDS DIRECTLY FROM THE DENSE FLUIDIZED BED ADAPTED TO BE MAINTAINED IN SAID VESSEL INTO EACH OF SAID CELLS, EACH OF SAID INLET PORTS BEING OF SUCH SIZE TO PRODUCE A SUBSTANTIAL PRESSURE DROP THROUGH THE PORTS TO EFFECT SUBSTANTIAL UNIFORM DISTRIBUTION OF THE SOLIDS TO EACH OF SAID CELLS, MEANS FOR INTRODUCING A STRIPPING AGENT INTO THE LOWER PORTION OF EACH OF SAID CELLS BELOW THE LOCUS OF SAID INLET PORTS WHEREBY SOLID PARTICLES PASSING DOWN THROUGH SAID CELLS ARE STRIPPED OF VOLATILE MATERIAL BY THE UPFLOWING STRIPPING AGENT AND THE STRIPPING AGENT AND STRIPPED-OUT MATERIAL ARE STRIPDUCED BY EACH OF SAID CELLS INTO THE UPPER PORTION OF SAID VESSEL ABOVE THE MAXIMUM LEVEL OF THE FLUIDIZED BED OF SOLID PARTICLES ADAPTED TO BE MAINTAINED IN SAID VESSEL, THE BOTTOM OF SAID CELLS COMMUNICATING WITH SAID BOTTOM OUTLET IN SAID VESSEL FOR REMOVAL OF SOLID PARTICLES FROM SAID VESSEL.
