A Comparison of Conversion Efficiency and Flow Restriction Performance of Ceramic and Metallic Catalyst Substrates

Catalyst systems utilizing ceramic and metallic substrates were compared to assess the influence of various substrate parameters on the exhaust gas conversion efficiency and flow restriction. In particular, the substrate surface area, substrate specific heat capacity, and substrate volume were all e...

Description
Summary:Catalyst systems utilizing ceramic and metallic substrates were compared to assess the influence of various substrate parameters on the exhaust gas conversion efficiency and flow restriction. In particular, the substrate surface area, substrate specific heat capacity, and substrate volume were all evaluated for their importance in estimating the conversion efficiency of the catalyst system. Additionally, substrate open frontal area and cell hydraulic diameter were compared against exhaust restriction performance.
