IN A METHOD FOR OPERATING A MULTIPLE BED CATALYST REFORMING SYSTEM TO PRODUCE HIGH OCTANE HYDROCARBONS, IN WHICH A DEACTIVATED CATALYST BED IS REGENERATED, THE STEPS WHICH COMPRISE MAINTAINING A FLOW OF NAPHTHA THROUGH THE SYSTEM WHILE THE SYSTEM IS UNDER REFORMING CONDITIONS INCLUDING A TEMPERATURE OF ABOUT 875 TO 975* F., REMOVING A REACTOR FROM THE SYSTEM AFTER THE CATALYST THEREIN HAS BECOME DEACTIVATED, REGENERATING THE CATALYST IN SAID REACTOR, AND PLACING SAID REACTOR BACK ON STREAM AT A POSITION SUBSEQUENT IN FLOW TO THE INITIAL REACTOR WHILE INTRODUCING TO SAID REACTOR CONTAINING THE REGENERATED CATALYST SUFFICIENT NAPHTHA ALONG WITH EFFLUENT FROM THE UPSTREAM REACTOR TO GIVE A TEMPERATURE NOT EXCEEDING ABOUT 1000*F. TO ESTABLISH STABLE REFORMING CONDITIONS.
