A new, simple method of determining the types of kinetic equations for which such a zone can appear was developed on the basis of simple mathematical transformations. It was shown that: (i) pellet geometry has no influence on necessary conditions of the origination of dead zone (ii) only driving-force term (in the sense of Langmuir-Hinshelwood-Hougen-Watson kinetic approach) decides if a dead zone is formed. A new algorithm which allows fast and precise evaluation of critical Thiele modulus Fcrit (in a catalyst pellet for F>Fcrit the dead zone appears) was proposed and tested.}, type={Artykuły / Articles}, title={CONDITIONS OF DEAD ZONE FORMING IN POROUS CATALYST PELLETS}, URL={http://www.journals.pan.pl/Content/103643/PDF/CPE-39-1-art_10_119104_10.pdf}, keywords={diffusion reaction processes, diffusional limitations, critical Thiele modulus}, }
