Integrated coking and calcining process

Claim 1

AN INTEGRATED COKING AND CALCINING PROCESS WHICH COMPRISES THE STEPS OF COKING A HEAVY HYDROCARBON OIL BY CONTACTING THE SAME WITH HOT COKE PARTICLES IN A COKING ZONE WHEREIN THE OIL IS CONVERTED TO PRODUCT VAPORS AND CARBONACEOUS SOLIDS ARE DEPOSITED ON THE COKE PARTICLES, REMOVING PRODUCT VAPORS FROM THE COKING ZONE,BURNING A PORTION OF COKE PARTICLES REMOVED FROM THE COKING ZONE IN A SEPARATE FIRST BURNING ZONE CONTAINING A DENSE FLUIDIZED BED OF COKE PARTICLES TO INCREASE THE TEMPERATURE OF SAID FLUIDIZED PARTICLES,RETURNING A PORTION OF THE HEATED COKE PARTICLES FROM THE BURNING ZONE OF THE COKING ZONE, PASSING AT HIGH VELOCITY A SEPARATED CONFINED STREAM OF COKE PARTICLES WITHOUT SUBSTANTIAL COOLING FROM THE FIRST BURNING ZONE THROUGH A TRANSFER LINE BURNING ZONE, THE STREAM OF COKE PARTICLES BEING FURTHER HEATED BY A HIGH VELOCITY BURNING STREAM OF COMBUSTIBLE GAS AND OXYGENCONTAINING GAS INTRODUCED AT THE INLET OF SAID TRANSFER LINE BURNING ZONE SO AS TO MINIMIZE REDUCTION OF CARBON DIOXIDE TO CARBON MONOXIDE AND BURNING OF THE COKE SEPARATING THE THUS HEATED COKE FROM THE RESULTANT CARBON DIOXIDE CONTAINING FLUE GAS,PASSING THE COKE TO A CALCINING ZONE,MAINTAINING THE COKE PARTICLES IN THE CALCINING ZONE AT A TEMPERATURE IN THE RANGE OF 2000*F. TO 2700*F. FOR FROM 5 MINUTES TO 8 HOURS AND REMOVING CALCINED COKE FROM THE CALCINING ZONE.
