ABSTRACT:
A hydrocarbon feedstock is catalytically reformed to effect dehydrocyclization of paraffins in a process combination comprising a first reforming zone and a sulfur-removal zone utilizing a manganese component to preclude sulfur from the feed to a second reforming zone. The process combination shows substantial benefits over prior art processes in the stability of the extremely sulfur-sensitive catalyst utilized in the second reforming zone.
