The monolith honeycomb structure is widely used as a catalyst support for gas treatment applications such as cleaning of automotive exhaust gases and industrial off-gases [1,2]. In these applications, in which large volumetric flows must be handled, monoliths offer certain advantages such as low pressure drop and high mechanical strength.
