Abstract:
1. A process for producing hydrogen in a reactor comprising: reacting at least one hydrocarbon and steam in the presence of a complex metal oxide and a steam-hydrocarbon reforming catalyst in a production step under reaction conditions sufficient to form hydrogen and a spent complex metal oxide comprising a metal carbonate, and reacting the spent complex metal oxide with an oxygen source gas in a regeneration step under reaction conditions sufficient to regenerate the complex metal oxide and to yield carbon dioxide, wherein the complex metal oxide is represented by the formula where A′ represents at least one element selected from the group consisting of Sr, Ba, a Group 1 element, and an element of the Lanthanide series according to the IUPAC Periodic Table of the Elements; B′ represents at least one element selected from the group consisting of Cu, Ni, Co, Cr, and V; and n represents a value such that the complex metal oxide is rendered electrically neutral.
