Aromatization and naphtha reforming process wherein the catalyst is dehydrated with a gas containing c1-c4 hydrocarbons

Claim 1

THE METHOD OF CONVERTING HYDROCARBONS BOILING IN THE NAPHTHA BOILING RANGE WHICH COMPRISES CONTACTING IN A REACTION ZONE THE SAID HYDROCARBONS WITH A CATALYST IN THE FORM OF A DENSE FLUIDIZED BED AND IN THE PRESENCE OF ADDED HYDROGEN AT ELEVATED TEMPERATURE AND PRESSURES FOR A SUFFICIENT PERIOD OF TIME TO EFFEFT THE FORMATION OF AROMATIC HYDROCARBONS, WITHDRAWING CATALYST CONTAMINATED WITH CARBONACEOUS AND OTHER DEPOSITS FROM THE REACTION ZONE, TREATING SAID CATALYST IN A REGENERATION ZONE WITH AN OXYGEN-CONTAINING GAS AT ELEVATED TEMPERATURES WHEREBY SUCH DEPOSITS ARE CONSUMED BY COMBUSTION AND REMOVED AS FUMES FROM THE CATALYST, WITHDRAWING THE REGENERATED CATALYST FROM THE REGENERATION ZONE, REMOVING WATER FROM THE REGENERATED CATALYST BY TREATING THE REGENERATED CATALYST WITH A GAS CONTAINING A PREDOMINANT AMOUNT OF C1-C4 HYDROCARBON FOR A PERIOD OF TIME OF FROM ABOUT 2-120 SECONDS, RETURNING THE REGENERATED CATALYST SUBSTANTIALLY FREE OF WATER TO THE REACTION ZONE AND FEEDING WATER TO THE REACTION ZONE IN AN AMOUNT OF FROM ABOUT 1/4-2 MOL PERCENT BASED ON THE HYDROGEN ENTERING THE CONVERSION ZONE.

Claim 2

THE METHOD OF CONVERTING HYDROCARBONS BOILING IN THE NAPHTHA BOILING RANGE WHICH COMPRISES CONTACTING IN A REACTION ZONE THE SAID HYDROCARBONS WITH A CATALYST IN THE FORM OF A DENSE FLUIDIZED BED AND IN THE PRESENCE OF ADDED HYDROGEN AT ELEVATED TEMPERATURE AND PRESSURES FOR A SUFFICIENT PERIOD OF TIME TO EFFEFT THE FORMATION OF AROMATIC HYDROCARBONS, WITHDRAWING CATALYST CONTAMINATED WITH CARBONACEOUS AND OTHER DEPOSITS FROM THE REACTION ZONE, TREATING SAID CATALYST IN A REGENERATION ZONE WITH AN OXYGEN-CONTAINING GAS AT ELEVATED TEMPERATURES WHEREBY SUCH DEPOSITS ARE CONSUMED BY COMBUSTION AND REMOVED AS FUMES FROM THE CATALYST, WITHDRAWING THE REGENERATED CATALYST FROM THE REGENERATION ZONE, REMOVING WATER FROM THE REGENERATED CATALYST BY TREATING THE REGENERATED CATALYST WITH A GAS CONTAINING A PREDOMINANT AMOUNT OF C1-C4 HYDROCARBON FOR A PERIOD OF TIME OF FROM ABOUT 2-120 SECONDS, RETURNING THE REGENERATED CATALYST SUBSTANTIALLY FREE OF WATER TO THE REACTION ZONE AND FEEDING WATER TO THE REACTION ZONE IN AN AMOUNT OF FROM ABOUT 1/4-2 MOL PERCENT BASED ON THE HYDROGEN ENTERING THE CONVERSION ZONE.
