TY - JOUR TI - Diffusion with chemical reaction – assessment of the accuracy of an approximate kinetic model for spherical pellets AU - Gwadera, Monika TI - Diffusion with chemical reaction – assessment of the accuracy of an approximate kinetic model for spherical pellets AB - Diffusion with a first-order chemical reaction in a spherical pellet of a catalyst with third-type boundary conditions was considered; such a process can be described by a kinetic model based on the continued fraction approximation. Results of calculations obtained from an approximate kinetic model were compared with the exact solution. It was found that the application of this approximate model provides a good level of accuracy and requires short calculation times.
