Redox reaction facilitated carbon dioxide capture from flue gas and conversion to carbon monoxide

A method of operating a reactor system, the method comprising:

• providing oxygen carrier particles to a first reactor, the oxygen carrier particles comprising a support material and metal oxide;
• providing flue gas comprising carbon dioxide (CO2) to the first reactor;
• operating the first reactor at a temperature of 300° C. to 700° C.;
• collecting a first reactor gas output comprising less than 1 ppb CO2;
• providing the oxygen carrier particles to a second reactor;
• providing a hydrocarbon stream to the second reactor;
• operating the second reactor at a temperature of 500° C. to 1100° C.;
• collecting a second reactor gas output comprising hydrogen gas (H2) and carbon monoxide (CO);
• providing the oxygen carrier particles to a third reactor;
• providing an oxidizing stream to the third reactor;
• and
• collecting a third reactor gas output comprising carbon monoxide (CO).
