Combination hydrocarbon vaporization and cracking process

Claim 1

IN A CONTINUOUS CYCLIC HYDROCARBON CONVERSION PROCESS WHEREIN A FINELY DIVIDED ADSORBENT CONTACT MATERIAL IS PASSED CYCLICALLY THROUGH A HYDROCARBON CONVERSION ZONE WHEREIN IT CONTACTS A VAPORIZED HYDROCARBON CHARGE TO EFFECT THE CONVERSION THEREOF TO LOWER BOILING GASOLINE CONTAINING PRODUCTS AND THROUGH A CONTACT MATERIAL REGENERATING ZONE WHEREIN CARBONACEOUS CONTAMINANTS DEPOSITED UPON THE CONTACT MATERIAL DURING SAID HYDROCARBON CONVERSION ARE BURNED, THE METHOD FOR CONDITIONING A HIGH BOILING LIQUID FRACTION TO PROVIDE THEREFROM A SUITABLE VAPORIZED HYDROCARBON CHARGE FOR SAID CONVERSION ZONE WHICH COMPRISES: MAINTAINING A SUBSTANTIALLY COMPACT COLUMN OF DOWNWARDLY MOVING HEAT ABSORPTIVE MATERIAL IN A CONFINED PARTIAL CONVERSION ZONE, PASSING SAID HIGH BOILING LIQUID FRACTION INTO CONTACT WITH SAID COLUMN TO EFFECT ITS CONVERSION TO A LOWER BOILING VAPORIZED HYDROCARBON FRACTION SUITABLE FOR CHARGING TO SAID CONVERSION ZONE, SAID CONVERSION RESULTING IN THE DEPOSITION OF A CARBONACEOUS DEPOSIT UPON SAID HEAT ABSORPTIVE MATERIAL, PASSING SAID VAPORIZED FRACTION TO SAID CONVERSION ZONE AS THE HYDROCARBON CHARGE THERETO, SUBSTANTIALLY CONTINUOUSLY WITHDRAWING USED HEAT ABSORPTIVE MATERIAL BEARING CARBONACEOUS DEPOSIT FROM THE LOWER SECTION OF SAID PARTIAL CONVERSION ZONE AND SUPPLYING HEATED HEAT ABSORPTIVE MATERIAL INTO THE UPPER SECTION OF SAID PARTIAL CONVERSION ZONE AT A RATE CONTROLLED TO SUPPLY THE HEAT REQUIRED FOR THE CONVERSION OF SAID LIQUID FRACTION TO SAID VAPORIZED FRACTION, PHYSICALLY EFFECTING THE REMOVAL OF CARBONACEOUS DEPOSITS FROM SAID USED HEAT ABSORPTIVE MATERIAL, SEPARATING THE CONTACT MATERIAL FROM THE REMOVAL CARBONACEOUS MATERIAL AND PASSING IT THROUGH A SEPARATE HEATING ZONE, PASSING A SUITABLE HEATING GAS INTO CONTACT WITH SAID HEAT ABSORBING MATERIAL IN SAID HEATING ZONE TO CAUSE SAID MATERIAL TO ABSORB A SUBSTANTIAL AMOUNT OF HEAT, RETURNING THE HEATED HEAT ABSORPTIVE MATERIAL TO SAID PARTIAL CONVERSION ZONE AS THE SUPPLY THERETO, SAID HEAT ABSORPTIVE MATERIAL BEING CAPSULES CONTAINING A FUSIBLE SUBSTANCE CAPABLE OF RELEASING LATENT HEAT AT A TEMPERATURE LEVEL BELOW THAT AT WHICH EXCESSIVE CONVERSION OF SAID LIQUID HYDROCARBON FRACTION TO GAS AND COKE WOULD OCCUR AND ABOVE THAT AT WHICH SAID VAPORIZED HYDROCARBON FRACTION FORMED IN SAID PARTIAL CONVERSION ZONE WILL CONDENSE.
