Abstract

Heterogeneous catalytic processes and biocatalitic processes are the most important types of the processes where existence of zones without reactants were reported. The aim of the work is justification of presence of dead zone in the catalyst pellet by experimental verification of a model solution. Good consistency of theretical and experimental results justify that dead zone is present inside the catalyst pellet.
