Faster is Better: The Effect of Internal Turbulence on DOC Efficiency 2006-01-1525

A number of metallic oxidation catalyst substrates with advanced internal structures have emerged in the past few years. In an aftertreatment application, these structures improve gas mixing by increasing turbulence within the substrate's matrix. Modeling results show these advanced structures, under some operating conditions, can be correlated to reductions in catalyst substrate volume and precious metal 1,2.
Three structured metallics were compared to a baseline ceramic substrate in a designed experiment to understand the effect of advanced metallic substrates on diesel oxidation catalyst (DOC) sizing and performance. The results showed that smaller metallic DOCs coated with up to 30% less precious metal (PM) catalyst performed on par or better than the baseline ceramic DOC in terms of hydrocarbon conversion, heat-up, and pressure drop.
