Characteristics of various new oxygen carriers for CLC - Various materials specially prepared for the use of chemical looping combustion (CLC) were characterized thermogravimetrically (TG). The materials tested were three types of nickel and iron based carriers: 1) nickel based carriers; 2) iron based material 3) iron-nickel compositions in alumina matrix. In the nickel based carriers, the NiO was mixed with Al2O3 matrix, which had particle sizes of 1 µm, 3-4 µm and 10 ?m, respectively. The effect of alumina support materials particle size to reactivity was tested in TG. Packing in agglomeration and sintering was thought to be affected by the alumina particle size. Two 60 %Fe2O3/ 40% Al2O3 mixtures with different particle sizes and one 57% Fe2O3 + % NiO/ 40 % Al2O3 mixtures were also tested. Smaller particle size was considered to increase reaction rate and NiO addition was considered to increase reactivity.
