Methods to increase the efficiency of a metallic monolithic catalyst

The increasing interest in using metallic monolithic catalysts for automotive emission control raises certain optimization possibilities. Creating obstacles in the channels by disfiguring the channel wall in the manufacturing process can give rise to an increased transport rate to the catalyst wall...

Description
Summary:The increasing interest in using metallic monolithic catalysts for automotive emission control raises certain optimization possibilities. Creating obstacles in the channels by disfiguring the channel wall in the manufacturing process can give rise to an increased transport rate to the catalyst wall and an increased reaction rate in the wash-coat. In the present mathematical simulation study, the decrease in the residual carbon monoxide at the outlet and the accompanying pressure drop increase were calculated for different designs of the metallic monolithic catalyst. A standard unsegmented monolith without obstacles was compared with monoliths with two obstacles, monoliths with changed dimensions of the channels, and monoliths segmented into three separate pieces in series.
