Electrodes from fluid coke

Claim 1

A METHOD OF MAKING A CARBON ELECTRODE HAVING A MINIMUM REAL DENSITY OF ABOUT 1.45, A MAXIMUM RESISTIVITY OF 3X10-3 OHMI-INCH AND A MINIMUM COMPRESSION STRENGTH OF 4400 P. S. I. FROM A CHARGE OF FLUID COKE PARTICLES HAVING A DIAMETER DISTRIBUTING IN THE RANGE OF ABOUT 75-850 MICRONS WITH ABOUT 90 WEIGHT PRECENT HAVING A DIAMETER SMALLER THAN 400 MICRONS SAID FLUID COKE PARTICLES HAVING BEEN PRODUCED BY CONTACTING A HEAVY PETROLEUM AOIL COKING CHARGE STOCK AT A COKING TEMPERATURE WITH A BODY OF FLUIDED COKE PARTICLES IN A REACTION ZONE WHEREIN THE OIL IS CONVERTED TO PRODUCT VAPORS AND CARBONACEOUS SOLIDS ARE CONTINUOUSLY DEPOSITED ON THE COKE PARTICLES, REMOVING PRODUCT VAPORS FROM THE COKING ZONE, HEATING A PORTION OF THE COKE PARTICLES FROM THE COKING ZONE IN A HEATING ZONE TO INCREASE THE TEMPERATURE OF SAID FLUIDIZED PARTICLES, RETURNING A PORTION OF THE HEATED COKE PARTICLES FROM THE HEATING ZONE TO THE COKING ZONE AND WIRHDRDAWING COKE PRODUCT PARTICLES, WHICH COMPRISES THE STEPS OF CALCINING THE FLUID COKE PARTICLES TO A REAL DENSITY OF 1.87-1.92; GRINDING THE CALCINED FLUID COKE PARTICLES SO THAT 20-50 WEIGHT PERCENT OF THE FLUID COKE CHARGE HAS A DIAMETER OF LESS THAN 75 MICRONS; ADMIXING THE GROUND FLUID COKE WITH A CARBONACEOUS BINDER IN THE RATIO OF APPROXIMATELY 18-45 PARTS BY WT. PER 100 PARTS OF FLUID COKE; AND BAKUNG THE MUXTURE AT A TEMPERATURE IN THE RANGE OF 1700-2400*F.

Claim 2

A METHOD OF MAKING A CARBON ELECTRODE HAVING A MINIMUM REAL DENSITY OF ABOUT 1.45, A MAXIMUM RESISTIVITY OF 3X10-3 OHMI-INCH AND A MINIMUM COMPRESSION STRENGTH OF 4400 P. S. I. FROM A CHARGE OF FLUID COKE PARTICLES HAVING A DIAMETER DISTRIBUTING IN THE RANGE OF ABOUT 75-850 MICRONS WITH ABOUT 90 WEIGHT PRECENT HAVING A DIAMETER SMALLER THAN 400 MICRONS SAID FLUID COKE PARTICLES HAVING BEEN PRODUCED BY CONTACTING A HEAVY PETROLEUM AOIL COKING CHARGE STOCK AT A COKING TEMPERATURE WITH A BODY OF FLUIDED COKE PARTICLES IN A REACTION ZONE WHEREIN THE OIL IS CONVERTED TO PRODUCT VAPORS AND CARBONACEOUS SOLIDS ARE CONTINUOUSLY DEPOSITED ON THE COKE PARTICLES, REMOVING PRODUCT VAPORS FROM THE COKING ZONE, HEATING A PORTION OF THE COKE PARTICLES FROM THE COKING ZONE IN A HEATING ZONE TO INCREASE THE TEMPERATURE OF SAID FLUIDIZED PARTICLES, RETURNING A PORTION OF THE HEATED COKE PARTICLES FROM THE HEATING ZONE TO THE COKING ZONE AND WIRHDRDAWING COKE PRODUCT PARTICLES, WHICH COMPRISES THE STEPS OF CALCINING THE FLUID COKE PARTICLES TO A REAL DENSITY OF 1.87-1.92; GRINDING THE CALCINED FLUID COKE PARTICLES SO THAT 20-50 WEIGHT PERCENT OF THE FLUID COKE CHARGE HAS A DIAMETER OF LESS THAN 75 MICRONS; ADMIXING THE GROUND FLUID COKE WITH A CARBONACEOUS BINDER IN THE RATIO OF APPROXIMATELY 18-45 PARTS BY WT. PER 100 PARTS OF FLUID COKE; AND BAKUNG THE MUXTURE AT A TEMPERATURE IN THE RANGE OF 1700-2400*F.
