Abstract

Recent developments in thin-walled, honeycomb-type catalyst supports have provided advantages for reaction chemistry due to greater honeycomb geometry surface areas. However, the developments have provided disadvantages for some practical manufacturing issues that follow from weaker mechanical properties. Satisfactory load-bearing strength is necessary to survive manufacturing stresses such as those from compressing a honeycomb into its metal can. With the square honeycomb cell structures, this strength is highly anisotropic, so fractures occur along the columns (or equivalently rows) of the honeycomb with any slight misalignment
