Abstract
An apparatus for making hydrogen from a hydrocarbon feedstock and steam using heat stored in a vessel followed by the regeneration of the vessel to restore the heat. Regeneration is done by preheating within the vessel a hydrogen purge gas and steam. Downstream of the conventional reform catalyst, the preheated gases are mixed with an oxygen containing gas so that they combust within the vessel in a fuel lean mode and heat material disposed in the vessel. This is the heat which is used in converting the hydrogen feedstock to hydrogen. The addition of steam in the regeneration process to recover the heat remaining in the vessel following the hydrogen make cycle simplifies reactor bed design and improves operational flexibility. Incorporation of a regeneratable sulfur absorber in the vessel facilitates the removal of up to 90% of the feedstock sulfur.
