In the hydrogen production process within a chemical loop, the utilization of redox reactions of metal oxides is expected to facilitate the generation of high-purity hydrogen. This research aims to employ iron sand as the metal oxide and biomass as the reducing material. It investigates the particle size, shape, and fluidization characteristics of the iron sand during the chemical loop reaction, with the objective of achieving multiple cycles. The study also examines the influence of factors such as gas flow rate during reduction in the chemical loop and the ratio of biomass to iron sand on the particle size of the iron sand.
