Reforming followed by hydrodealkylation

Claim 1

THE METHOD OF PRODUCING HIGH OCTANE GASOLINE AND AROMATICS OF HIGH PURITY WHICH COMPRISES SUBJECTING A NAPHTHA CONTAINING NAPHTHENES WHICH ARE PREDOMINANTLY C9-C11 HYDROCARBONS AND BOILING SUBSTANTIALLY WITHIN THE RANGE OF 250*-450*F. TO A HYDROFORMING OPERATION IN THE PRESENCE OF A FLUIDIZED BED OF HYDROFORMING CATALYST, RECOVERING A HYDROFORMED PRODUCT FROM THE HYDROFORMING STEP, RECOVERING A GAS RICH IN HYDROGEN FROM THE SAID HYDROFORMING STEP SEPARATING A MOTOR GASOLINE FRACTION FROM SAID HYDROFORMED PRODUCT, RECOVERING HIGH BOILING ALKYLATED AROMATICS FROM SAID HYDROFORMED PRODUCT, PREHEATING SAID AROMATICS TO A TEMPERATURE OF FROM ABOUT 800*-900*F. AND THEREAFTER SUBJECTING SAID AROMATICS TO HYDRODEALKYLATION IN THE PRESENCE OF A FLUIDIZED BED OFPOWDERED INERT NON-CATALYTIC MATERIAL AND IN THE PRESENCE OF ADDED HYDROGEN RECOVERED FROM THE SAID HYDROFORMING STEP AND RECOVERING THEREFROM BENZENE, TOLUENE AND XYLENE ISOMERS.

Claim 2

THE METHOD OF PRODUCING HIGH OCTANE GASOLINE AND AROMATICS OF HIGH PURITY WHICH COMPRISES SUBJECTING A NAPHTHA CONTAINING NAPHTHENES WHICH ARE PREDOMINANTLY C9-C11 HYDROCARBONS AND BOILING SUBSTANTIALLY WITHIN THE RANGE OF 250*-450*F. TO A HYDROFORMING OPERATION IN THE PRESENCE OF A FLUIDIZED BED OF HYDROFORMING CATALYST, RECOVERING A HYDROFORMED PRODUCT FROM THE HYDROFORMING STEP, RECOVERING A GAS RICH IN HYDROGEN FROM THE SAID HYDROFORMING STEP SEPARATING A MOTOR GASOLINE FRACTION FROM SAID HYDROFORMED PRODUCT, RECOVERING HIGH BOILING ALKYLATED AROMATICS FROM SAID HYDROFORMED PRODUCT, PREHEATING SAID AROMATICS TO A TEMPERATURE OF FROM ABOUT 800*-900*F. AND THEREAFTER SUBJECTING SAID AROMATICS TO HYDRODEALKYLATION IN THE PRESENCE OF A FLUIDIZED BED OFPOWDERED INERT NON-CATALYTIC MATERIAL AND IN THE PRESENCE OF ADDED HYDROGEN RECOVERED FROM THE SAID HYDROFORMING STEP AND RECOVERING THEREFROM BENZENE, TOLUENE AND XYLENE ISOMERS.
