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. This heating fluid may be directed through the tube portion of the convective reformer, or alternatively, through the shell portion, either of which may be filled with catalyst. The gas that emerges from the convective reformer, which has undergone heat exchange with the feed mixture may be used to preheat the feed mixture to the convective reformer.
