When practical utilization of hydrogen in blast furnace will be tried, mass transfer behavior of hydrogen under the upward gas flow should be correctly understood. The purpose of this study is to clarify that diffusion behavior of several kinds of gases in air flow through packed bed in order to understand diffusion behavior of hydrogen in blast furnace. Cold model experiments at room temperature were carried out to investigate the diffusion behavior of He and CH 4 gases in air flow through the packed bed. Experimental results were analyzed by R. W. FAHIEN's method and following conclusion was obtained. Effect of molecular species difference on gas diffusion behavior was appeared clearer in the condition of smaller air flow velocity than bigger one from this comparison. In other words, gas diffusion behavior could ignore difference of molecular species under enough large gas flow condition.
