Hydroforming with the use of a mixture

Claim 1

THE METHOD OF SUPPLYING A MAJOR PORTION OF THE HEAT REQUIRED FOR HYDROFORMING NAPHTHAS TO THE HYDROFORMING REACTION ZONE IN A SYSTEM COMPRISING A HYDROFORMING ZONE CONTAINING A FLUIDIZED BED OF FINELY DIVIDED CATALYST, A REGENERATION ZONE CONTAINING A FLUIDIZED BED OF FINELY DIVIDED CATALYST AND TRANSFER LINES CONNECTING THE SAID HYDROFORMING ZONE AND SAID REGENERATION ZONE WHICH COMPRISES FLUIDIZING THE FINELY DIVIDED CATALYST AND SHOT PARTICLES HAVING A HIGHER DENSITY AND LARGER AVERAGE PARTICLE SIZE THAN THE CATALYST IN THE HYDROFORMING REACTION ZONE BY THE PASSAGE OF GASIFORM REACTANT MATERIAL UPWARDLY THROUGH SAID ZONE, PASSING FLUIDIZED CATALYST AND SHOT DOWNWARDLY THROUGH A WELL OF REDUCED CROSSSECTIONAL AREA DISPOSED AT THE BOTTOM OF THE HYDROFORMING ZONE, INTRODUCING RECYCLE GAS NEAR THE BOTTOM OF SAID WELL AND CAUSING SAID RECYCLE GAS TO FLOW UPWARDLY THROUGH SAID WELL AT A SUFFICIENT VELOCITY TO GAS LIFT CATALYST FROM SAID WELL INTO THE BOTTOM OF THE FLUIDIZED BED OF CATALYST IN THE REACTION ZONE WHEREBY THE REACTIVE PROPORTION OF SHOT TO CATALYST IN SAID WELL IS INCREASED, DISCHARGING THE RESULTANT MIXTURE OF SHOT AND CATALYST FROM THE BOTTOM OF SAID WELL IN THE FORM OF A CONFINED STREAM OF RESTRICTED CROSS-SECTIONAL AREA, PASSING SAID MIXTURE DOWNWARDLY, THEN WITH CHANGING DIRECTION TO A REGION OF FLOW REVERSED WHEREIN AT ITS LOWERMOST POINT A FIRST MIXTURE RICH IN SHOT PARTICLES IS CONCENTRATED AND A SECOND MIXTURE LEAN IN SHOT IS CONCENTRATED ABOVE THE FIRST MIXTURE, PASSING SAID SECOND MIXTURE AS A CONFINED STREAM WITH CHANGING DIRECTION THEN UPWARDLY TO COMPLETE A U-SHAPED PATH OF REVERSED FLOW TO THE UPPER PORTION OF THE DENSE BED IN THE HYDROFORMING REACTION ZONE, WITHDRAWING SAID FIRST MIXTURE RICH IN SHOT DOWNWARDLY FROM SAID LOWERMOST POINT OF FLOW REVERSAL AND PASSING SAID MIXTURE IN THE FORM OF A CONFINED STREAM INTO THE REGENERATING ZONE, MAINTAINING IN THE REGENERATION ZONE A HIGHER RATIO OF SHOT TO CATALYST THAN EXISTS IN THE HYDROFORMING ZONE, SUBJECTING THE MIXTURE TO OXIDATIVE REGENERATION AND RETURNING A HIGHLY HEATED MIXTURE OF SHOT AND CATALYST TO THE HYDROFORMING ZONE.

Claim 2

THE METHOD OF SUPPLYING A MAJOR PORTION OF THE HEAT REQUIRED FOR HYDROFORMING NAPHTHAS TO THE HYDROFORMING REACTION ZONE IN A SYSTEM COMPRISING A HYDROFORMING ZONE CONTAINING A FLUIDIZED BED OF FINELY DIVIDED CATALYST, A REGENERATION ZONE CONTAINING A FLUIDIZED BED OF FINELY DIVIDED CATALYST AND TRANSFER LINES CONNECTING THE SAID HYDROFORMING ZONE AND SAID REGENERATION ZONE WHICH COMPRISES FLUIDIZING THE FINELY DIVIDED CATALYST AND SHOT PARTICLES HAVING A HIGHER DENSITY AND LARGER AVERAGE PARTICLE SIZE THAN THE CATALYST IN THE HYDROFORMING REACTION ZONE BY THE PASSAGE OF GASIFORM REACTANT MATERIAL UPWARDLY THROUGH SAID ZONE, PASSING FLUIDIZED CATALYST AND SHOT DOWNWARDLY THROUGH A WELL OF REDUCED CROSSSECTIONAL AREA DISPOSED AT THE BOTTOM OF THE HYDROFORMING ZONE, INTRODUCING RECYCLE GAS NEAR THE BOTTOM OF SAID WELL AND CAUSING SAID RECYCLE GAS TO FLOW UPWARDLY THROUGH SAID WELL AT A SUFFICIENT VELOCITY TO GAS LIFT CATALYST FROM SAID WELL INTO THE BOTTOM OF THE FLUIDIZED BED OF CATALYST IN THE REACTION ZONE WHEREBY THE REACTIVE PROPORTION OF SHOT TO CATALYST IN SAID WELL IS INCREASED, DISCHARGING THE RESULTANT MIXTURE OF SHOT AND CATALYST FROM THE BOTTOM OF SAID WELL IN THE FORM OF A CONFINED STREAM OF RESTRICTED CROSS-SECTIONAL AREA, PASSING SAID MIXTURE DOWNWARDLY, THEN WITH CHANGING DIRECTION TO A REGION OF FLOW REVERSED WHEREIN AT ITS LOWERMOST POINT A FIRST MIXTURE RICH IN SHOT PARTICLES IS CONCENTRATED AND A SECOND MIXTURE LEAN IN SHOT IS CONCENTRATED ABOVE THE FIRST MIXTURE, PASSING SAID SECOND MIXTURE AS A CONFINED STREAM WITH CHANGING DIRECTION THEN UPWARDLY TO COMPLETE A U-SHAPED PATH OF REVERSED FLOW TO THE UPPER PORTION OF THE DENSE BED IN THE HYDROFORMING REACTION ZONE, WITHDRAWING SAID FIRST MIXTURE RICH IN SHOT DOWNWARDLY FROM SAID LOWERMOST POINT OF FLOW REVERSAL AND PASSING SAID MIXTURE IN THE FORM OF A CONFINED STREAM INTO THE REGENERATING ZONE, MAINTAINING IN THE REGENERATION ZONE A HIGHER RATIO OF SHOT TO CATALYST THAN EXISTS IN THE HYDROFORMING ZONE, SUBJECTING THE MIXTURE TO OXIDATIVE REGENERATION AND RETURNING A HIGHLY HEATED MIXTURE OF SHOT AND CATALYST TO THE HYDROFORMING ZONE.
