The specific surface areas as well as the total pore volumes were evaluated for these dehyd* rocyclization catalysts using the nitrogen adsorption technique. From the nitrogen adsorption isotherms, the pore size distribution curves could alto be derived; theses curves indicated the presence of a group of micropores which are inaccessible to larger reactant molecules in the catalystic aromatization reaction. The result* of pore structure analysis of these catalysts were related as much as possible to their catalystic activities.
