    In this paper, four different manganese minerals were tested in a batch fluidized bed reactor to evaluate their performance in the chemical looping combustion (CLC) of solid fuels. The char gasifiion rate in the experiments with the manganese minerals tested was higher than the corresponding values for ilmenite and iron ore, which were taken as benchmark materials.
