Sulfur recovery unit (SRU) converts H2S to elemental sulfur by Claus process. The process occurs during two combustion and catalytic reactions. Alumina ( Al2O3 ) and bauxite ( 2 3 2 Al O .H O ) are the main Claus catalysts. The volume distribution of micro- and macro-pores and the parameter of Bethe lattice representing the complex structure of catalyst pellets pores are the most important parameters affecting catalyst performance. This research is aimed at evaluating these parameters impact on effective efficiency of catalyst bed after blocking by liquid sulfur for the second and third reactors. It can be done by considering micro- and macro-pores as a function of pellets diameter. The results show that pellets with a minimum micro- and macro-pores volume and coordination number or Bethe lattice parameter of 6 are more suitable to use in catalytic reactors. There is a great consistency between modeling results and industrial ones.
