Abstract

<p>This study aimed to achieve continuous hydrogen generation through the direct reduction of iron sand with woody biomass. Increasing the biomass/iron sand mass ratio resulted in an increase in hydrogen production. However, supplying an excess of biomass had an impact on the fluidization within the fluidized bed, leading to a weakening of the reduction efficiency. In experiments where the particle size of the iron sand was varied, it was observed that larger particle sizes were advantageous. It is necessary to discuss the effects of these factors on iron content, thermal stability, and reactivity of the samples.</p>
