TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: In the formulation, one of the first and second oxides comprises a metal oxide. The adjuvant comprises a carbon compound, preferably graphite. The mass proportion of the adjuvant is 5-20%, preferably 10% with respect to the mixture of oxides. In the mixture of oxides, the mass proportion of dopant is 35-45%, preferably 40%, and reagent is 65-55%, preferably 60%. The reagent comprises at least one oxide comprising nickel oxide, ferrous oxide, copper oxide (preferred), and cobalt oxide. The dopant comprises at least one oxide comprising manganese dioxide, titanium dioxide, aluminum oxide, magnesium oxide, and calcium oxide (preferred). The third stream comprises a gas stream comprising air, air enriched with oxygen, oxygen, carbon monoxide, carbon dioxide, or any oxidized compound. The first and second oxide comprises a metal oxide. The FG1 is natural gas, methane, hydrogen, carbon monoxide, or oxidizable compound. The FG2 is composed of a gas stream comprising air, oxygen (O2) enriched air, O2, carbon dioxide, or any oxidized compound. The reaction temperature during reduction and oxidation is 550-1000 degrees C, preferably 950 degrees C. Preferred Process: The process further comprises: homogenizing the mixture of reagent, dopant and adjuvant by mixing; dispersing the mixture of reagent, dopant and adjuvant in distilled water; drying the mixture of dopant, reagent and adjuvant mixture, at a drying temperature of 110 degrees C; grinding the mixture of dopant, reagent and adjuvant to obtain particles with desired size; and calcining the mixture of dopant, reagent and adjuvant in the presence of a third gas stream comprising oxygen elements, where the calcining step is conducted until disappearance of the adjuvant in the mixture. The calcining the mixture of reagent, adjuvant and dopant is carried out at a temperature of 650-1050 degrees C, preferably 950 degrees C. The adjuvant is added in mass proportion of 5-20 mass%, preferably 10 mass% of the mixture of oxides. The mixture of oxides is obtained out with the dopant and the reagent. The gas stream treatment comprises combustion of FG1 in the presence of the formulation during the reduction step, where the process comprises chemical looping combustion (chemical looping combustion or thermochemical looping combustion). The process is catalysis process, which is carried out during the reduction step by oxidation of FG1, and/or during the oxidation step by reducing FG2. EXAMPLE - None given.
