摘要: One-dimensional heterogeneous model has been used for studying steady-state temperature profiles in adiabatic fixed-bed reactors.Since high temperature zone is determined by the temperature profile in the reactor, it is obviously of primary importance to study the effects affecting the steady-state temperature profiles. This paper shows how heat conductance of the packed catalysts, gas mixture and the reactor wall affect the temperature profile, and, a numerical example is given for illustration. It is indicated that the heat conductance of the laboratoryscale reactor wall is considerable and its effect is not negligible during scaling-up.
