Continuous utilization of industrial flue gas effluent for the thermochemical reforming of methane

A method of continuously processing flue gas, comprising:

• a) introducing a flue gas comprising CO2, H2O, O2, N2, SOx, and NO2 to a reduced solid oxide material, wherein the reduced material is in a fluidized bed reactor, wherein CO2 is not stored during this process;
• b) forming a first gas mixture comprising CO, H2, N2, SOx, and NO2 by performing a reduction reaction of the flue gas with the reduced solid oxide material, wherein the reduced solid oxide material is oxidized to form an oxidized solid material, wherein step b) is conducted in the fluidized bed reactor;
• c) separating the first gas mixture from the oxidized solid material, wherein the oxidized solid material is transferred from the fluidized bed reactor to a solar drop-tube reactor;
• d) introducing the oxidized solid material to a reducing environment;
• e) forming a second gas mixture by reducing the oxidized solid material to form the reduced solid oxide material, wherein step e) is conducted in the solar drop-tube reactor, wherein reduction includes using a solar radiation heat source and the solar drop-tube reactor has low partial pressure of oxygen (pO2);
• f) separating the second gas mixture from the reduced solid oxide material, wherein the reduced solid oxide material reduced is transferred to the fluidized bed reactor;
• and
• g) go to step a) to continuously process the flue gas, wherein steps a) and b) and d) and e) are decoupled from one another.
