The reaction and heat transfer characteristics of catalyst-coated fins, which are used to circumvent low catalyst loadings in wall-supported catalytic reactors, are investigated theoretically in an attempt to examine the effects of important non-dimensional parameters on fin performance for endothermic reaction cases. The fin efficiency of the reaction rate is found to decrease markedly, more than that of convection heat transfer, with an increase of heat absorption rate by the reaction and / or the convection heat transfer rate, for the case in which the conversion rate is governed by the intrinsic kinetics of the catalyst. The increase of bulk fluid temperature to the fin base temperature increases the fin efficiency of the reaction rate, under chemical kinetics limitation, due to convection heating of the fin while the fin temperature decreases along the structure due to heat absorption. An increase of the effect of convective mass transport on the reaction rate increases the fin efficiency of the reaction rate.
