Disclosed is a process for catalytically reforming a gasoline boiling range hydrocarbonaceous feedstock wherein the reforming is conducted in two or more stages wherein each stage is separated from another stage by aromatics removal from the reaction stream of a preceding stage. The resulting aromatics-lean stream is passed to a downstream reforming stage.
