Fluid system for use in conversion and reforming of hydrocarbons

Claim 1

A HYDROFORMING PROCESS WHEREIN A PETROLEUM NAPHTHA IS CONTACTED WITH A DENSE FLUIDIZED MASS OF FINELY DIVIDED REFORMING CATALYTIC SOLIDS IN THE PRESENCE OF HYDROGEN IN A REACTION ZONE THUS PRODUCING A REFORMED PRODUCT AND RESULTING IN THE DEPOSITION OF CARBONACEOUS MATERIAL ON THE CATALYST; THE STEPS INCLUDING THE WITHDRAWAL OF AT LEAST A PORTION OF CATALYST IN THE REACTION ZONE, MIXING THE WITHDRAWN CATALYST WITH CATALYST OF LESS CARBONACEOUS CONTENT IN A MIXING ZONE, PASSING THE MIXTURE OF CATALYST UPWARDLY IN AN ELONGATED CONFINED ZONE BY MEANS OF AN OXYGEN CONTAINING GAS WHEREBY AT LEAST A POETION OF THE CARBONACEOUS MATERIAL IS REMOVED BY BURNING, PASSING THE CATALYST FROM THE ELONGATED CONFINED ZONE TO A REGENERATION ZONE WHEREIN THE CATALYST IS FURTHER CONTACTED WITH OXYGEN CONTAINING GAS SO THAT THE TEMPERATURE OF THE CATALYST IS SUBSTANTIALLY GREATER THAN THE TEMPERATURE OF THE CATALYST IN THE REACTION ZONE, PASSING A PORTION OF THE HEATED CATALYST DOWNWARDLY THROUGH A PLURALITY OF ELONGATED CONFINED ZONES, ONE OF WHICH SURROUNDS THE FIRST MENTIONED ELONGATED CONFINED ZONE WHEREIN CATALYST PASSES UPWARDLY, THE DOWNWARDLY PASSING HEATED CATALYST INDIRECTLY TRANSFERS HEAT TO THE CATALYST IN THE REACTION
