Fluid hydroforming with inverse temperature gradient

Claim 1

IN THE METHOD OF REFORMING HYDROCARBONS IN CONTACT WITH A MIXTURE OF FINELY REFORMING CATALYST AND INERT HEAT TRANSFER SOLIDS IN A DENSE FLUIDIZED BED IN WHICH THE CATALYST PARTICLES AND INERT HEAT TRANSFER SOLIDS ARE CONTINUOUSLY CIRCULATED BETWEEN A REACTION AND REGENERATION ZONE THE IMPROVEMENT CATALYST AND INERT WITHDRAWING A MIXTURE OF REGENERATED CATALYST AND INERT HEAT TRANSFER SOLIDS FROM THE BOTTOM OF THE REGENERATOR DENSE BED, PASSING THIS MIXTURE THROUGH AN ELUTRIATION ZONE, SEPARATING A SUBSTANTIAL PART OF THE CATALYST PARTICLES FROM SAID MIXTURE AND RETURNING THE SEPARATED CATALYST PARTICLES TO THE REGENERATION ZONE, WITHDRAWING A STREAM COMPRISING A MAJOR PROPORTION OF HOT, INERT HEAT TRANSFER SOLIDS FROM SAID ELUTRAIATION ZONE, DISCHARGING SAID STREAM OF HOT, INERT HEAT TRANSFER SOLIDS INTO THE UPPER PART OF THE REACTION ZONE AND SUPPLYING VAPORUOUS REACTANTS TO THE BOTTOM OF SAID DENSE THEREBY ESTABLISHING AT THE UPPER PART OF SAID DENSE FLUIDIZED BED A ZONE OF HIGHER TEMPERATURE THAN THE AVERAGE TEMPERATURE IN THE MAIN REACTOR BED IN THE REACTION ZONE.
