This patent describes a process for catalytically reforming a gasoline boiling range hydrocarbonaceous feedstock in the presence of hydrogen in a reforming process unit comprised of a plurality of serially connected reactors wherein each of the reactors contains a supported noble metal-containing reforming catalyst composition. The process comprising: conducting the reforming it two or more stages comprised of one or more reactors; separating aromatics from at least a portion of the reaction stream between each stage thereby resulting in an aromatics-rich stream and an aromatics-lean stream; passing at least a portion of the aromatics-lean stream to the next downstream stage, in the substantial absence of non-reformed feed; and conducting the reforming of one or more of the downstream stages wherein at least one of the reactors contains a reforming catalyst.
