ABSTRACT:
Conventional noble metal reforming to upgrade the octane number of petroleum naphtha is an endothermic reaction which is carried out in a series of reactors with intermediate furnace heating of the petroleum fraction being upgraded. This specification discloses a process and apparatus configuration to increase the octane number of the reformate at a minimum liquid yield loss by cooling the first reforming stage effluent and then contacting the cooled effluent with a ZSM-5 type zeolite catalyst prior to the first intermediate furnace heating.
