  • Patent number: 10525427
    Abstract: A reactor for hydrocarbon production that separates wax reaction products from lightweight gaseous reaction products. The reactor has a housing, a catalyst bed, a product recovery zone, and a stripping zone. The catalyst bed can be provided in multi-tubular and other fixed bed configurations. The stripping zone receives light-weight gas reaction products from the product recovery zone, while a gas outlet of the housing receives non-lightweight gaseous hydrocarbon reaction products from the product recovery zone. A wax outlet of the housing receives wax products from the product recovery zone.
