Abstract
A chemical-looping combustion method uses a metallic oxide (MO) as an oxygen carrier. A fuel (RH) reduces MO at a low temperature in a first reactor, a reduced product (M) is oxidized by oxygen in moistened air in a high-temperature region in a second reactor to form MO which is recycled to the first reactor. Heat generated within these reactors is utilized to drive gas turbines. The reactions within the first and second reactors are: EQU RH+MO.fwdarw.mCO.sub.2 +nH.sub.2 O+M (1) EQU M+0.50.sub.2 .fwdarw.MO (2) Moistened air is the oxygen source in the second reaction. The metallic oxides and their reduced products are particulates including an oxygen permeable medium. The loss of energy in the conversion reactions and in heat exchange is reduced, power generation efficiency is improved, CO.sub.2 is recovered and water resources are saved.
