Abstract: The paper deals with description of deactivation kinetics of heterogeneous catalysts caused by irreversible chemisorption of catalyst poison. Three model deactivation mechanisms are considered: the homogeneous mechanism with one type and two types of active sites and the shell progressive mechanism. A method of models parameters estimation from the rotating basket reactor measurements is proposed. The method is illustrated by hydrogenation of benzene on a nickel catalyst with thiophene as poison.
