摘要：

The influence of the interfacial gradients on the performance of a fixed bed adiabatic catalytic reactor cannot generally be determined only at the reactor inlet conditions because the magnitude of the gradients vary along the reactor. A very simple method for the estimation from inlet conditions of the maximum interfacial temperature gradient is developed. A very good agreement with values obtained from the numerical solution of the balance equations is found. An analysis of the relative importance of the interfacial concentration and temperature gradients is also carried out. A parameter Lm, that is a good measure of the influence of each one of these gradients in the reactor, is introduced.
