Oxygen carrying materials

An oxygen carrying material comprising:

• 20% to 70% by weight of a primary active mass, the primary active mass comprising a composition having a metal or metal oxide selected from the group consisting of Fe, Co, Ni, Cu, Mo, Mn, Sn, Ru, Rh, and combinations thereof;
• 5% to 70% by weight of a primary support material, the primary support material comprising a composition having:
• (i) at least one metal, metal oxide, metal carbide, metal nitrate, metal halide, or combinations thereof, wherein the at least one metal, metal oxide, metal carbide, metal nitrate, or metal halide comprise metal elements selected from the group consisting of Li, Be, B, Na, Mg, Al, Si, K, Ca, Sc, Ti, V, Cr, Mn, Co, Zn, Ga, Ge, Rb, Sr, Y, Zr, Nb, Mo, Cd, In, Sn, Sb, Cs, Ba, La, Ce, Th, and combinations thereof;
• (ii) at least one ceramic or clay material, or salts thereof;
• (iii) at least one naturally occurring ore;
• or
• (iv) combinations thereof;
• and
• 1% to 35% by mass of a secondary support material, the secondary support material comprises a composition having:
• (i) at least one metal, metal oxide, metal carbide, metal nitrate, metal halide, or combinations thereof, wherein the at least one metal, metal oxide, metal carbide, metal nitrate, or metal halide comprise metal elements selected from the group consisting of Li, Be, B, Na, Mg, Al, Si, K, Ca, Sc, Ti, V, Cr, Mn, Co, Zn, Ga, Ge, Rb, Sr, Y, Zr, Nb, Mo, Cd, In, Sn, Sb, Cs, Ba, La, Ce, Th, and combinations thereof;
• (ii) at least one ceramic or clay material or salts thereof;
• (iii) at least one naturally occurring ore;
• or
• (iv) combinations thereof;
• wherein the primary support material composition and the secondary support material composition are different.
