Process for hydrofining and hydroforming hydrocarbons

Claim 1

A HYDROCARBON CONVERSION PROCESS WHICH COMPRISES TREATING A VIRGIN NAPHTHA IN A PRIMARY REACTION ZONE AT ELVATED TEMPERATURE AND PRESSURES IN CONTACT WITH A FLUIDIZED BED OF A FINELY DIVIDED HYDROFORMING CATALYST COMPRISING A GROUP VI METAL OXIDE UPON A SUPPORT AND IN THE PRESENCE OF HYDROGEN, WITHDRAWING REACTION PRODUCTS AND CATALYST PARTICLES SEPARATELY FROM SAID REACTION ZONE, TRANSFERRING THE WITHDRAWN CATALYST TO A REGENERATION ZONE, PASSING AN OXYGEN-CONTAINING REGENERATOR GAS THROUGH A FLUIDIZED BED OF CATALYST PARTICLES IN THE REGENERATION ZONE TO BURN CARBONACEOUS DEPOSITS FROM THE CATALYST PARTICLES, SEPARATING LIQUID PRODUCT AND PROCESS GASES FROM THE SAID REACTION PRODUCTS, RECYCLING A STREAM OF CATALYST FROM SAID REGENERATION ZONE TO SAID PRIMARY REACTION ZONE, RECYCLING A PORTION OF THE PROCESS GASES SEPARATED FROM THE REACTION PRODUCTS THE PRIMARY REACTION ZONE IN ORDER TO CONDITION CATALYST AND MAINTAIN HYDROGEN PARTIAL PRESSURE AS WELL AS TOTAL PRESSURE IN THE PRIMARY REACTION ZONE, WITHDRAWING A SECOND STREAM OF CATALYST FROM THE REGENERATION ZONE AND CONDUCTING THE SAME INTO A FLUIDIZED BED OF CATALYST PARTICLES IN A SECOND ARY TREATING ZONE, SUPPLYING A REFINERY STREAM REQUIRING CLEAN UP TO SAID SECONDARY TREATING ZONE AND SUPPLYING THE EXCESS OF PROCESS GAS NOT REQUIRED FOR RECYCLE TO THE PRIMARY REACTION ZONE TO THE SECONDARY TREATING ZONE, MAINTAINING THE PRESSURE IN THE SECONDARY TREATING ZONE THE SAME AS IN THE PRIMARY REACTION ZONE, MAINTAINING THE TEMPERATURE AND THE SPACE VELOCITY IN THE SECONDARY TREATING ZONE LOWER THAN IN THE PRIMARY REACTION ZONE AND WITHDRAWING A STREAM OF CATALYST PARTICLES FROM THE SECONDARY TREATING ZONE AND RECYCLING THE SAME TO THE REGENERATION ZONE IN ADMIXTURE WITH AIR TO BURN CARBONACEOUS DEPOSITS THEREFROM.
