摘要：
The effect produced by the content of different size pores and the diameter of a catalyst grain on the deactivation rate has been estimated based on the experimental data on the conversion of H2S in the Claus reaction. Catalysts with different pore size distributions have been used for analysis. Deactivation has been shown to occur in different fashions for a fine catalyst fraction and catalyst grains. A mathematical model that describes the process of deactivation has been proposed.
