Summary:

Diesel particulate filters (DPF) made from Dow's advanced ceramic material (ACM) have already demonstrated high filtration efficiency, low pressure drop, and high temperature performance capabilities. In addition to these advantages of the ACM-DPF, it has been found to be well suited for use in combination with various catalyst coatings while maintaining it's overall advanced performance over a broad range of catalyst loadings. Our recent studies on catalyzed ACM DPF demonstrate that the unique micro structure of ACM is able to maintain significant amount of catalyst and washcoats. The characteristics of the ACM DPF pressure drop versus catalyst washcoats loading have been fully investigated. With defined coating techniques, ACM DPF can be loaded with three times the amount of washcoat than can a Silicon Carbide DPF without significantly increasing the pressure drop. This enables a broad catalyst selection and multiple functions on a catalyzed DPF design as well as for single brick soot or four-way system applications
