Refortification of aluminum halidehydrocarbon complex catalyst

Claim 1

A PROCESS FOR REFORTIFICATION OF AN ALUMINUM HALIDE-HYDROCARBON COMPLEX FROM A PACKED UPRIGHT CYLINDRICAL COLUMN OF SOLID PARTICULATE ALUMINUM HALIDE CONTAINING A PLURALITY OF VERTICALLY DISPOSED CONTIGUOUS SECTIONS WHICH COMPRISES INTRODUCING A SUSPENDING LIQUID UNREACTIVE WITH ALUMINUM HALIDE UNDER SUSPENDING CONDITIONS TO THE BOTTOM OF THE TOP SECTION OF SAID COLUMN BELOW THE UPPER LEVEL OF SAID PARTICULATE ALUMINUM HALIDE THROUGH A SERIES OF INJECTION ZONES CIRCUMFERENTIALLY DISPOSED IN RELATION TO SAID COLUMN, EACH BEING INWARDLY DIRECTED AT AN ANGLE OF ABOUT 45* TO A RADIUS OF SAID COLUMN INTERSECTING EACH SAID ZONE AND AT AN ANGLE OF ABOUT 45* TO THE HORIZONTAL, AND WITHDRAWING LIQUID AND SUSPENDED ALUMINUM HALIDE AT THE LIQUID LEVEL AXIALLY OF SAID COLUMN SO AS TO CAUSE SAID SUSPENDING LIQUID TO PASS OBLIQUELY AND SPIRALLY THROUGH SAID COLUMN; WHEN THE ALUMINUM HALIDE HAS BEEN SUSPENDED AND REMOVED FROM SAID TOP SECTION, SUSPENDING AND REMOVING THE ALUMINUM HALIDE FROM THE NEXT LOWER SECTION BY THE PROCEDURE UTILIZED IN SAID TOP SECTION; CONTINUING THE SUSPENSION AND REMOVAL OF ALUMINUM HALIDE FROM EACH PROGRESSIVELY LOWER SECTION OF SAID COLUMN UNTIL THE SAME HAS BEEN DEPLETED; AND PASSING THE LIQUID SUSPENSION OF ALUMINUM HALIDE INTO CONTACT WITH AN ALUMINUM HALIDE-HYDROCARBON COMPLEX SO AS TO REFORTIFY SAME.
