Abstract:
1. A power-generation method comprising: reacting within a first reaction-temperature range a carbonaceous or hydrogen fuel with a material in an oxygen-rich form in a first reactor to convert said material to an oxygen-poor form and to produce a first off gas containing carbon dioxide and water; transferring said material in its oxygen-poor form to a second reactor; introducing air into said second reactor for reaction within a second reaction-temperature range with said material in its oxygen-poor form to convert said material to its oxygen-rich form and to produce a second off gas, the highest level of said second reaction-temperature range being less than the highest level of said first reaction-temperature range; and transferring said material in its oxygen-rich form from said second reactor to said first reactor.
