  • Multistage reforming with interstage aromatics removal
    Patent number: 4975178
    Abstract: 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. Reforming in at least one of the downstream reactors is conducted in the presence of a catalyst comprised of a nobel metal, an inorganic support, and a promotor metal; or a catalyst comprised of a Group VIII metal on a type-X, type-Y, or type-L zeolitic support.
