Apparatus for producing hydrogen

摘要

A fuel processor for converting a hydrocarbon or an oxygenate feed stream to produce a fuel stream for a fuel cell is provided wherein the heat required to sustain the reforming reaction and the cooling required to moderate and direct high and low-temperature shift reactions occur in a thermosiphon boiler vessel (100). The thermosiphon boiler vessel (100) provides an essentially isothermal steam generator and heat removal system which improves the stability of the integrated reaction zone by providing a uniform temperature profile and strategic temperature control.
