Abstract
A reactor for hydrocarbon fuel is provided. The reactor uses interconnected fluidized beds (IFB) in chemical-looping combustion for multi-stage reduction reactions of an iron-based oxygen carrier, namely hematite (Fe2O3). Three-phase reduction reactions of Fe2O3 are accurately and completely controlled. The three-phase reduction reactions are separately processed while oxygen in Fe2O3 is fully released. Carbon dioxide with high purity is further obtained while hydrogen can be generated as a byproduct under a certain condition. Hence, the present invention has fast throughput, high-efficiency operation and low cost.
