Recovery of aluminum chloride from a fluid aluminum chloride-hydrocarbon complex

Claim 1

A PROCESS FOR RECOVERY OF AN ALUMINUM HALIDE FROM A FLUID ALUMINUM HALIDE-HYDROCARBON COMPLEX WHICH COMPRISES SPRAYING THE SAID COMPLEX IN FINELY DIVIDED FORM INTO A FLUIDIZED SOLIDS BED REACTION ZONE MAINTAINED AT AN ELEVATED TEMPERATURE SUITABLE FOR THE DECOMPOSITION OF THE SAID COMPLEX, MAINTAINING THE SAID COMPLEX IN SAID ZONE FOR A CONTROLLED TIME SUFFICIENT TO DECOMPOSED THE SAME TO FORM ALUMINUM CHLORIDE VAPORS AND A FINELY DIVIDED CARBONACEOUS RESIDUE DEPOSITED UPON THE FLUIDIZED SOLIDS IN SAID ZONE, WITHDRAWING ALUMINUM CHLORIDE VAPORS FROM SAID ZONE AND CONDENSING THE SAME AS A PRODUCT OF THE PROCESS, WITHDRAWING FLUIDIZED SOLIDS HAVING CARBONACEOUS RESIDUE DEPOSITED THEREON FROM SAID ZONE, AND PASSING SAID SOLIDS TO A REGENERATION ZONE, IN SAID REGENERATION ZONE REMOVING THE CARBON DEPOSITED UPON SAID SOLIDS IN SAID FLUIDIZED SOLIDS BED REACTION ZONE THEREBY REGENERATING AND REHEATING SAID PARTICLES FOR REUSE IN SAID FLUIDIZED SOLIDS BED REACTION ZONE, RETURNING SAID SOLIDS TO SAID FLUIDIZED SOLIDS BED REACTION ZONE FOR REUSE, REMOVING ALSO HYDROCARBON VAPORS FROM SAID FLUIDIZED SOLIDS REACTION ZONE AND RECOVERING THE SAME SUBSTANTIALLY FREE FROM ALUMINUM CHLORIDE AND THEN FLUIDIZING SAID SOLIDS BY EMPLOYING BY RECYCLE THE SAID HYDROCARBON VAPORS AS A FLUIDIZING MEDIUM FOR THE FLUIDIZATION OF SAID SOLIDS IN SAID FLUIDIZED SOLIDS BED REACTION ZONE.
