In this section, the impact of ore to biomass mass ratio (O/B) is discussed. It should be pointed out that OC is only used in the chemical looping process for the production of syngas or H 2, while iron ore is used as a raw material for ironmaking in the shaft furnace. Therefore, OC/B is aimed at the chemical looping process, while O/B is aimed ...
