Reactor-generator apparatus

A high temperature reactor-generator apparatus for the high temperature conversion of a reactant stream of which reforming hydrocarbons into gaseous products, dissociating ammonia, partial oxidation of hydrocarbon feeds, high temperature catalytic reforming and the like are examples. The apparatus comprises a pressure vessel, a conduit within the vessel having upper and lower ends and sides spaced from the pressure vessel walls, a partition intermediate the ends of the conduit member and spanning the space between the vessel and the conduit member to divide the interior of the vessel into an upper reactor chamber and lower reactor chamber, means for introducing a fluid reactant into the lower chamber for flow therethrough and upwardly through the conduit into the upper reactor chamber, a heat supply for heating the lower reactor chamber, a reaction products outlet from the upper chamber and means for supplying heat to the lower reactor chamber for causing the reaction. The means for flowing a fluid in heat exchange relationship with the upper reactor chamber may take any form desired such as a fluid coil in the upper chamber or an injector for injecting the fluid directly into contact with the fluids in the upper chamber.
