Abstract
A simple approximate procedure is developed for the estimation of the effec tiveness factor of the reactions, which enables the resistance due to inter nal diffusion to be taken into account at any point of the reactor without resorting to numerical integration of the diffusion equations in the pellet . A comparison is presented between the effectiveness factor eta obtained v ia the integration of the diffusion equations and that calculated using the linearized reaction rate equations.
