A raw material composition for producing oxygen carriers includes a first component which is one or more of nickel oxide and nickel hydroxide and a second component which is one or more of boehmite, cerium oxide, cerium hydroxide, magnesium oxide, magnesium hydroxide, and titanium oxide, wherein, when the first component is nickel oxide, the second component includes cerium hydroxide. Such a raw material composition for producing oxygen carriers of the present invention is formed into oxygen carriers according to an oxygen carrier producing method, which will be described below, by adjusting the composition, formulation of raw materials, and degree of homogenization. Then, it is possible to produce oxygen carriers having physical properties such as a shape, a particle size, and a particle distribution suitable for a fluidized bed process or a high speed fluidized bed process and having improved wear-resistance, long-term durability, and oxygen transfer performance.
