摘要：

Temperature and concentration profiles were measured in the presence of an exothermic chemical reaction along the axis and the wall of a wall-cooled packed bed reactor. The data allowed the discrimination of three approaches to evaluate wall heat fluxes in solving the equations of the quasi-homogeneous model. All model coefficients were obtained from literature data. At Reynolds numbers of 25 and 32 (related to inlet temperatures around 600 K) the wall heat conduction model turned out to be the superior one.
