Fluid hydroforming process and apparatus

Claim 1

IN A FLUIDIZED CATALYST HYDROFORMING PROCESS THE IMPROVEMENT WHICH COMPRISES INCREASING CATALYST EFFCIENCY BY INTRODUCING VAPORIZED FEED AND RECYCLE GAS WELL DISTRIBUTE HORIZONTALLY INTO THE BOTTOM OF A VERTICAL REACTOR ZONE CONTAINING TWO VERTICALLY SPACED DENSE FLUIDIZED BEDS OF FINELY DIVIDED HYDROFORMING CATALYST PARTICLES SEPERATED FROM EACH OTHER BY A HIGH, 1-2.5 P.S.I., PRESSURE DROP SEPERATION ZONE, CONTINOUSLY SUPPLYING HIGHLY ACTIVE CATALYST TO THE LOWER FLUID BED AND CONTINUOUSLY WITHDRAWING A STREAM OF CATALYST FROM THE UPPER FLUID BED FROM REGENERATION, CIRCULATING A STREAM OF CATALYST FROM THE UPPER FLUID BED TO THE LOWER FLUID BED, CIRCULATING ANOTHER SMALLER EXTERNAL STREAM FROM THE LOWER FLUID BED TO THE UPPER BED MAINTAINING SAID LOWER FLUID BED ZONE AT A TEMPERATURE OF 920 TO 955*F. AND SAID UPPER FLUID BED ZONE AT A TEMPERATURE OF 900 TO 925* F., AND LOCATING THE SEPARATION ZONE FOR THE PARTICULAR TEMPERATURES OF THE UPPER AND LOWER ZONES AND CATALYST CIRCULATION RATES SO AS TO OBTAIN ABOVE 80% OF THE TOTAL CONVERSION OF REACTANTS IN THE LOWER FLUID BED ZONE.
