Abstract

An integrated gasification iron-air electrical system, capable of generating electrical energy from a carbon containing material, is made, the system containing a gasification furnace having at least one gasification reactor zone where a carbonaceous material contacts and reacts with a gas containing steam, to produce a hot gas reaction product containing CO and H2 ; where the hot gas then contacts discharged iron electrodes at over 450° C., to convert discharged iron compounds to iron compounds, and the recharged iron electrodes are then placed in iron-air cells which generate electrical energy.
