Processing hydrocarbons

Claim 1

THE METHOD WHICH COMPRISES FLOWING A VAPOR STREAM INTO A BODY OF HOT FRESHLY REGENERATED GRANULAR CRACKING CATALYST UNDER PRESSURE TO EFFECT SUSPENSION OF CATALYST IN THE STREAM, SAID VAPOR STREAM ESSENTIALLY COMPRISING CRACKABLE HYDROCARBONS AND BEING SUBSTANTIALLY FREE OF UNVAPORIZED LIQUID HYDROCARBONS, TRANSPORTING THE CATALYST UNDER THE IMPELLING INFLUENCE OF THE SUSPENDING VAPORS THROUGH AN UPFLOW PATH, DISENGAGING CATALYST FROM VAPORS AT THE UPPER END OF SAID UPFLOW PATH, THEREAFTER PASSING THE STILL HOT CATALYST IN DOWNWARD DIRECTION TO SUPPLY A GRAVITATING COMPACT BED THEREOF WITH A CONTINUOUSLY REPLENISHED UPPER SURFACE, AT LEAST A PORTION OF THE CATALYST SO SUPPLIED BEING PASSED THROUGH A LIQUID CONTACT ZONE WHEREIN IT IS CONTACTED WITH HYDROCARBON OIL IN LIQUID STATE, SAID OIL BEING AT A TEMPERATURE BELOW THAT OF SAID CATALYST AND BEING VAPORIZED BY TRANSFER OF CONTAINED SENSIBLE HEAT FROM CATALYST PASSED THROUGH SAID LIQUID CONTACT ZONE; PASSING VAPORIZED OIL THUS PRODUCED, TOGETHER WITH THE OTHER HYDROCARBON VAPORS DISENGAGED AT THE UPPER END OF SAID UPFLOW PATH, THROUGH SAID COMPACT BED OF CATALYST WHILE SAID CATALYST IS STILL A HYDROCARBON CONVERSION TEMPERATURE, TO EFFECT FURTHER REACTION AND CONVERSION OF SAID VAPORIZED OIL AND THE OTHER HYDROCARBON VAPORS; THE PROPORTIONATE QUANTITY OF HYDROCARBON IN THE VAPOR STREAM EMPLOYED FOR SUSPENDING AND TRANSPORTING THE CATLYST THROUGH SAID UPFLOW PATH BEING SELECTED WITH RESPECT TO THE DIFFERENCE IN TEMPERATURE OF THE CATALYST AND SUCH VAPORS, THAT COOLING OF CATALYST DURING SUCH TRANSPORTATION IS NOT IN EXCESS OF 100* F. AND THE BODY OF HOT FRESHLY REGENERATED CATALYST ORIGINALLY SUSPENDED IN SAID TRANSPORTING VAPOR STREAM BEING AT A TEMPERATURE AND HAVING A HEAT CONTENT AT LEAST SUFFICIENT TO SUPPLY THE HEAT REQUIRED FOR VAPORIZATION OF SAID LIQUID HYDROCARBON OIL AND FOR CONVERSION OF HYDROCARBONS OF THE SAID VAPORIZED OIL AS WELL AS THE SAID OTHER HYDROCARBON VAPORS.

Claim 2

THE METHOD WHICH COMPRISES FLOWING A VAPOR STREAM INTO A BODY OF HOT FRESHLY REGENERATED GRANULAR CRACKING CATALYST UNDER PRESSURE TO EFFECT SUSPENSION OF CATALYST IN THE STREAM, SAID VAPOR STREAM ESSENTIALLY COMPRISING CRACKABLE HYDROCARBONS AND BEING SUBSTANTIALLY FREE OF UNVAPORIZED LIQUID HYDROCARBONS, TRANSPORTING THE CATALYST UNDER THE IMPELLING INFLUENCE OF THE SUSPENDING VAPORS THROUGH AN UPFLOW PATH, DISENGAGING CATALYST FROM VAPORS AT THE UPPER END OF SAID UPFLOW PATH, THEREAFTER PASSING THE STILL HOT CATALYST IN DOWNWARD DIRECTION TO SUPPLY A GRAVITATING COMPACT BED THEREOF WITH A CONTINUOUSLY REPLENISHED UPPER SURFACE, AT LEAST A PORTION OF THE CATALYST SO SUPPLIED BEING PASSED THROUGH A LIQUID CONTACT ZONE WHEREIN IT IS CONTACTED WITH HYDROCARBON OIL IN LIQUID STATE, SAID OIL BEING AT A TEMPERATURE BELOW THAT OF SAID CATALYST AND BEING VAPORIZED BY TRANSFER OF CONTAINED SENSIBLE HEAT FROM CATALYST PASSED THROUGH SAID LIQUID CONTACT ZONE; PASSING VAPORIZED OIL THUS PRODUCED, TOGETHER WITH THE OTHER HYDROCARBON VAPORS DISENGAGED AT THE UPPER END OF SAID UPFLOW PATH, THROUGH SAID COMPACT BED OF CATALYST WHILE SAID CATALYST IS STILL A HYDROCARBON CONVERSION TEMPERATURE, TO EFFECT FURTHER REACTION AND CONVERSION OF SAID VAPORIZED OIL AND THE OTHER HYDROCARBON VAPORS; THE PROPORTIONATE QUANTITY OF HYDROCARBON IN THE VAPOR STREAM EMPLOYED FOR SUSPENDING AND TRANSPORTING THE CATLYST THROUGH SAID UPFLOW PATH BEING SELECTED WITH RESPECT TO THE DIFFERENCE IN TEMPERATURE OF THE CATALYST AND SUCH VAPORS, THAT COOLING OF CATALYST DURING SUCH TRANSPORTATION IS NOT IN EXCESS OF 100* F. AND THE BODY OF HOT FRESHLY REGENERATED CATALYST ORIGINALLY SUSPENDED IN SAID TRANSPORTING VAPOR STREAM BEING AT A TEMPERATURE AND HAVING A HEAT CONTENT AT LEAST SUFFICIENT TO SUPPLY THE HEAT REQUIRED FOR VAPORIZATION OF SAID LIQUID HYDROCARBON OIL AND FOR CONVERSION OF HYDROCARBONS OF THE SAID VAPORIZED OIL AS WELL AS THE SAID OTHER HYDROCARBON VAPORS.
