ABSTRACT:
An apparatus for burning coal to produce substantially pure hydrogen for use in fuel cells, together with “sequestration ready” carbon dioxide and a stream of oxygen depleted air for powering gas turbines. The apparatus includes two fluidized bed reactors and a third transfer line reactor. The first reactor is supplied with coal particles or “char” and fluidized with high temperature steam. The second reactor is fluidized with high temperature steam and the third reactor is fluidized by compressed air. Solids circulated among these three reactors include a mixture of materials containing coal, calcium compounds (present as CaO, CaCO3and mixtures thereof) and iron compounds (present as FeO, Fe2O3and mixtures thereof).
