Authors previously advocated a mathematical model regarding the nonsiothermal fixed bed and its numerical calculation method. The present study concerns the application of this model to a small shaft reactor in order to obtain characteristics of heat transfer between gas and solid and heat loss through the wall of reactor, using steel balls as packed material. Overall heat transfer coefficient through the wall, U, was evaluated to be 26.8 kcal/cm^2 hr℃ with the aid of measured values of temperature at various levels reached to steady state conditions. By using the value of U simulation was made to longitudinal distribution of temperature for gas and solid, and well represented the measured values with the laps of time at various levels in the bed under nonsteady state condition. Hence, the value of U together with heat transfer coefficient between gas and solid can be utilized to the analysis of the case of moving bed reactor.
