In response to the changing needs of the auto manufacturers in meeting the more stringent emission standards legislated for 1980 and post-1980 model years, beaded catalysts with improved activity and durability have been developed. This has been achieved largely as a result of modifying the physical characteristics of the alumina substrate. Changes in density, pore size distribution and geometrical surface area, coupled with improved techniques of distributing noble metals, have resulted in catalysts with significantly improved durability. Furthermore, we have been able to build into the catalysts added degrees of physical and thermal stability, while still maintaining catalyst performance.
