Abstract:
1. A plant for generating electricity, comprising: a gas turbine; a compressor driven by the gas turbine; a reduction reactor configured to reduce metal oxides solids, the reduction reactor being fed with a fuel and the metal oxide solids via separate inlets so as to form a first circulating fluidized bed, wherein the metal oxides solids are mixed metal oxide solids that contain nickel; a first cyclone configured to separate the metal oxide solids, the first cyclone feeding at least a portion of the metal oxide solids to the reduction reactor via a first connecting line; an oxidation reactor configured to oxidize the metal oxide solids having a second circulating fluidized bed, wherein the oxidation reactor is fed with pressurized air from the compressor; and a second cyclone configured to separate the metal oxide solids, the second cyclone feeding at least a portion of the metal oxide solids to the oxidation reactor via a second connecting line.
