Fluid hydroforming process

Claim 1

IN A METHOD OF REFORMING HYDROCARBON FRACTIONS BOILING WITHIN THE NAPHTHA RANGE IN CONTACT WITH A MIXTURE OF A MAJOR PROPORTION OF FINELY DIVIDED REFORMING CATALYST PARTICLES AND A MINOR PROPORTION OF INERT HEAT TRANSFER SOLID PARTICLES IN A DENSE, FLUIDIZED BED, THE IMPROVEMENT WHICH COMPRISES DISCHARGING A MIXTURE OF INERT SOLIDS AND CATALYST INTO AN ELUTRIATING ZONE, PASSING FLUIDIZING GAS THROUGH SAID ELUTRIATING ZONE AT A LOWER RATE THAN THE MINIMUM FLUIDIZING VELOCITY FOR THE INERT SOLIDS BUT ABOVE THE MINIMUM FLUIDIZING VELOCITY FOR THE CATALYST PARTICLES DISCHARGING INERT SOLIDS SUBSTANTIALLY FREE FROM CATALYST PARTICLES FROM THE BOTTOM OF THE ELUTRIATING ZONE INTO A STRIPPING ZONE, PASSING A STRIPPING GAS THROUGH SAID STRIPPING ZONE AT A SUFFICIENT VELOCITY TO FLUIDIZE THE INERT SOLIDS, TRANSFERRING THE FLUIDIZED INERT SOLIDS FROM THE BOTTOM OF SAID STRIPPING ZONE TO A HEATING ZONE AND RECYCLING THE HEATED INERT HEAT TRANSFER SOLIDS TO THE REACTION ZONE.
