  • Patent number: 5181937
    Abstract: A convective reformer device is provided which is useful for partially reforming a feed mixture of hydrocarbons and steam. The device includes an outer shell enclosure and a tubular inner core assembly and is specifically adapted to support heat exchange between a heating fluid, which may be an effluent from downstream, and the hydrocarbon-steam feed mixture. The convective reformer is used in a system and process for the steam reformation of hydrocarbons, in which the partially reformed effluent from the convective reformer is further reformed in a steam reforming furnace, or an auto-thermal reformer, or a steam reforming furnace followed by an auto-thermal reformer. The fully reformed effluent from the steam reformer, or auto-thermal reformer, is directed back to the convective reformer to supply the heat of reaction for the partial reformation of the feed mixture.
    Type: Grant
