Conversion of hydrocarbons with suspended catalyst

Claim 1

A METHOD OF OPERATING CATALYTIC CONVERSION SYSTEM WHICH COMPRISES INTRODUCING A STREAM OF HYDROCARBONS INTO THE LOWER PORTION OF AN ENLARGED REACTION ZONE, INTRODUCING FINELY DIVIDED CATALYST INTO SAID REACTION ZONE, PASSING THE HYDROCARBONS IN VAPOR FORM UPWARDLY THROUGH THE REACTION ZONE AT A VELOCITY SUFFICIENT TO CARRY OVERHEAD FROM SAID ZONE SUBSTANTIALLY ALL OF THE CATALYST PARTICLES THEREIN CONTAINED, MAINTAINING THE RATE OF INTRODUCTION OF THE CATALYST THERETO SUFFFICIENT TO PROVIDE A MOBILE, TURBULENT, SUBSTANTIALLY LIQUID-LIKE SUSPENSION OF CATALYST AND VAPOR IN THE REACTION ZONE HAVING A CATALYST CONCENTRATION OF UPWARDS OF 3% BY VOLUME, WITHDRAWING VAPOROUS CONVERSION PRODUCTS FROM THE UPPER END OF THE REACTION ZONE, WITHDRAWING CATALYST CONTAINING ENTRAINED VAPORS FROM THE REACTION ZONE, STRIPPING THE CATALYST TO REMOVE ENTRAINED VAPORS THEREFROM, INTRODUCING THE STRIPPED CATALYST INTO AN ENLARGED REGENERATION ZONE, PASSING REGENERATION GAS UPWARDLY THROUGH THE REGENERATION ZONE AT A VELOCITY SUFFICIENT TO CARRY OVERHEAD FROM SAID ZONE SUBSTANTIALLY ALL OF THE CATALYST PARTICLES CONTAINED THEREIN, MAINTAINING THE RATE OF INTRODUCTION OF CATALYST TO SAID REGENERATION ZONE SUFFICIENT TO PROVIDE A MOBILE, TURBULENT, SUBSTANTIALLY LIQUID-LIKE SUSPENSION OF CATALYST AND REGENERATION GAS IN THE REGENERATION ZONE HAVING A CATALYST CONCENTRATION UPWARDS OF 3% BY VOLUME, WITHDRAWING REGENERATED CATALYST FROM THE REGENERATION ZONE AND RETURNING REGENERATED CATALYST TO THE REACTION ZONE.

Claim 2

A METHOD OF OPERATING CATALYTIC CONVERSION SYSTEM WHICH COMPRISES INTRODUCING A STREAM OF HYDROCARBONS INTO THE LOWER PORTION OF AN ENLARGED REACTION ZONE, INTRODUCING FINELY DIVIDED CATALYST INTO SAID REACTION ZONE, PASSING THE HYDROCARBONS IN VAPOR FORM UPWARDLY THROUGH THE REACTION ZONE AT A VELOCITY SUFFICIENT TO CARRY OVERHEAD FROM SAID ZONE SUBSTANTIALLY ALL OF THE CATALYST PARTICLES THEREIN CONTAINED, MAINTAINING THE RATE OF INTRODUCTION OF THE CATALYST THERETO SUFFFICIENT TO PROVIDE A MOBILE, TURBULENT, SUBSTANTIALLY LIQUID-LIKE SUSPENSION OF CATALYST AND VAPOR IN THE REACTION ZONE HAVING A CATALYST CONCENTRATION OF UPWARDS OF 3% BY VOLUME, WITHDRAWING VAPOROUS CONVERSION PRODUCTS FROM THE UPPER END OF THE REACTION ZONE, WITHDRAWING CATALYST CONTAINING ENTRAINED VAPORS FROM THE REACTION ZONE, STRIPPING THE CATALYST TO REMOVE ENTRAINED VAPORS THEREFROM, INTRODUCING THE STRIPPED CATALYST INTO AN ENLARGED REGENERATION ZONE, PASSING REGENERATION GAS UPWARDLY THROUGH THE REGENERATION ZONE AT A VELOCITY SUFFICIENT TO CARRY OVERHEAD FROM SAID ZONE SUBSTANTIALLY ALL OF THE CATALYST PARTICLES CONTAINED THEREIN, MAINTAINING THE RATE OF INTRODUCTION OF CATALYST TO SAID REGENERATION ZONE SUFFICIENT TO PROVIDE A MOBILE, TURBULENT, SUBSTANTIALLY LIQUID-LIKE SUSPENSION OF CATALYST AND REGENERATION GAS IN THE REGENERATION ZONE HAVING A CATALYST CONCENTRATION UPWARDS OF 3% BY VOLUME, WITHDRAWING REGENERATED CATALYST FROM THE REGENERATION ZONE AND RETURNING REGENERATED CATALYST TO THE REACTION ZONE.
