Abstract
Abstract A combination process for the production of an unleaded, narrow boiling range, high octane motor fuel which involves (1) a novel form of low-severity hydrocracking followed by (2) catalytic reforming. The process is effected without the intermediate separation of the product effluent from the low-severity hydrocracking zone, and, therefore, provides a true ''''in-line'''' hydrocracking/reforming combination process.

Claim 1
Independent Claim
151 words
A PROCESS FOR THE PRODUCTION OF A HIGH OCTANE MOTOR FUEL WHICH COMPRISES THE STEPS OF A. REACTING NAPHTHA BOILING RANGE HYDROCARBONS, CONTAINING CYCLIC COMPONENTS, WITH HYDROGEN, IN A FIRST REACTION ZONE, IN CONTACT WITH A FIRST CATALYTIC COMPOSITE OF A GROUP VIII NOBLE METAL COMPONENT AND A ZEOLITE ALUMINOSILICATE CARRIER MATERIAL AND AT A TEMPERATURE IN THE RANGE OF ABOUT 350*F. TO ABOUT 800*F AND A PRESSURE FROM ABOUT 100 TO ABOUT 400 PSIG. B. REACTING THE RESULTING FIRST REACTION ZONE EFFLUENT, WITHOUT INTERMEDIATE SEPARATION THEREOF, IN A SECOND REACTION ZONE, IN CONTACT WITH A SECOND CATALYTIC COMPOSITE COMPRISING PLATINUM AND ALUMINUM, AT A TEMPERATURE IN THE RANGE OF ABOUT 800*F TO ABOUT 1,100*F AND A PRESSURE OF FROM 100 TO BOUT 400 PSIG; SAID TEMPERATURE AND PRESSURE SELECTED TO CONVERT NAPHTHENES TO AROMATIC HYDROCARBONS; AND, C. RECOVERING SAID HIGH OCTANE NOTOR FUEL FROM THE RESULTING SECOND REACTION ZONE EFFLUENT.
