Fluid hydroforming operation

Claim 1

IN A PROCESS FOR HYDROFORMING HYDROCARBONS BOILING WITHIN THE MOTOR FUEL RANGE IN CONTACT WITH FINELY DIVIDED HYDROFORMING CATALYST PARTICLES CONSISTING ESSENTIALLY OF A GROUP VI METAL OXIDE UPON A CARRIER IN ACCORDANCE WITH THE FLUIDIZED SOLIDS TECHNIQUE AT TEMPERATURES BETWEEN ABOUT 850 AND 925* F., AT PRESSURES BETWEEN ABOUT 50 TO 500 LBS. PER SQ INCH AND AT CATALYST TO OIL WEIGHT RATIOS OF ABOUT 0.5 TO 1.5, THE IMPROVEMENT WHICH COMPRISES CONTINUOUSLY WITHDRAWING A STREAM OF SPENT CATALYST PARTICLES FROM A DENSE FLUIDIZED BED OF CATALYST PARTICLES IN THE REACTION ZONE, REGENERATING THE WITHDRAWN CATALYST PARTICLES BURNING CARBONACEOUS DEPOSITS THEREFROM WITH AN EXCESS OF AIR IN A REGENERATION ZONE, WITHDRAWING A STREAM OF REGENERATED CATALYST FROM THE REGENERATION ZONE, STRIPPING THE REGENERATED CATALYST WITH A NON-REDUCING STRIPPING GAS TO SUBSTANTIALLY FREE THE REGENERATED CATALYST OF CARBON OXIDES AND FREE OXYGEN AND WITHOUT CONTACTING THE FRESHLY REGENERATED CATALYST WITH HYDROGEN-CONTAINING OR OTHER REDUCING GASES DISCHARGING THE FRESHLY REGENERATED CATALYST DIRECTLY INTO THE DENSE FLUIDIZED BED OF CATALYST PARTICLES IN THE REACTION ZONE WHEREBY THE FRESHLY REGENERATED CATALYST PARTICLES ARE TREATED WITH HYDROGEN-CONTAINING REACTANT GASES WHILE IN INTIMATE MIXTURE WITH THE MAIN BODY OF REACTOR CATALYST IN THE REACTION ZONE AT SUBSTANTIALLY REACTION ZONE TEMPERATURE.
