Method for manufacturing coke

Claim 1

A METHOD FOR CONVERTING A HYDROCARBON OIL TO FORM COKE IN A CONTINUOUS CONVERSION SYSTEM WHICH COMPRISES IN COMBINATION THE STEPS OF HEATING COKE PARTICLES IN A FIRST HEATING ZONE; GRAVITATING SAID HEATED COKE PARTICLES FROM SAID FIRST HEATING ZONE THROUGH A COOLING ZONE TO A REACTION ZONE; PASSING A RELATIVELY COOL GAS INTO DIRECT HEAT EXCHANGE WITH SAID COKE PARTICLES IN THE LOWER PORTION OF SAID COOLING ZONE AND COUNTER TO THE FLOW OF SAID GRAVITATING HEATED COKE PARTICLES THEREIN; COATING SAID HEATED COKE PARTICLES WITH HYDROCARBON OIL INTERMEDIATE SAID COOLING ZONE AND SAID REACTION ZONE; BRINGING SAID HYDROCARBON OIL TO REACTION TEMPERATURE AND CONVERTING A PORTION THEREOF TO COKE ON SAID COKE PARTICLES BY DIRECT HEAT EXCHANGE WITH SAID HEATED COKE PARTICLES; GRAVITATING SAID COKE PARTICLES FROM SAID REACTION ZONE TO A SECOND HEATING ZONE; PASSING GASEOUS EFFLUENT FROM THE UPPER PORTION OF SAID COOLING ZONE INTO THE LOWER PORTION OF SAID SECOND HEATING ZONE SO THAT PREVIOUSLY UNREACTED HYDROCARBON MATERIALS ARE REACTED AND STRIPPED FROM SAID COKE PARTICLES; REMOVING GASEOUS EFFLUENT FROM THE UPPER PORTION OF SAID SECOND HEATING ZONE AND RESULTING GASEOUS REACTION PRODUCTS FROM THE LOWER PORTION OF SAID REACTION ZONE; GRAVITATING SAID COKE PARTICLES FROM SAID SECOND HEATING ZONE; ELEVATING SAID COKE PARTICLES TO SAID HEATING ZONE; AND WITHDRAWING A PORTION OF SAID CALCINED COKE PARTICLES FROM THE BOTTOM OF SAID COOLING ZONE.

Claim 2

A METHOD FOR CONVERTING A HYDROCARBON OIL TO FORM COKE IN A CONTINUOUS CONVERSION SYSTEM WHICH COMPRISES IN COMBINATION THE STEPS OF HEATING COKE PARTICLES IN A FIRST HEATING ZONE; GRAVITATING SAID HEATED COKE PARTICLES FROM SAID FIRST HEATING ZONE THROUGH A COOLING ZONE TO A REACTION ZONE; PASSING A RELATIVELY COOL GAS INTO DIRECT HEAT EXCHANGE WITH SAID COKE PARTICLES IN THE LOWER PORTION OF SAID COOLING ZONE AND COUNTER TO THE FLOW OF SAID GRAVITATING HEATED COKE PARTICLES THEREIN; COATING SAID HEATED COKE PARTICLES WITH HYDROCARBON OIL INTERMEDIATE SAID COOLING ZONE AND SAID REACTION ZONE; BRINGING SAID HYDROCARBON OIL TO REACTION TEMPERATURE AND CONVERTING A PORTION THEREOF TO COKE ON SAID COKE PARTICLES BY DIRECT HEAT EXCHANGE WITH SAID HEATED COKE PARTICLES; GRAVITATING SAID COKE PARTICLES FROM SAID REACTION ZONE TO A SECOND HEATING ZONE; PASSING GASEOUS EFFLUENT FROM THE UPPER PORTION OF SAID COOLING ZONE INTO THE LOWER PORTION OF SAID SECOND HEATING ZONE SO THAT PREVIOUSLY UNREACTED HYDROCARBON MATERIALS ARE REACTED AND STRIPPED FROM SAID COKE PARTICLES; REMOVING GASEOUS EFFLUENT FROM THE UPPER PORTION OF SAID SECOND HEATING ZONE AND RESULTING GASEOUS REACTION PRODUCTS FROM THE LOWER PORTION OF SAID REACTION ZONE; GRAVITATING SAID COKE PARTICLES FROM SAID SECOND HEATING ZONE; ELEVATING SAID COKE PARTICLES TO SAID HEATING ZONE; AND WITHDRAWING A PORTION OF SAID CALCINED COKE PARTICLES FROM THE BOTTOM OF SAID COOLING ZONE.
