Description | PNNL houses a vast array of advanced surface science instruments and experts to understand the implications of bio-derived blendstocks on current and emerging state-of-the-art aftertreatment catalysts. Technologies such as advanced three-way catalysts, diesel oxidation catalysts, selective catalytic reduction catalysts, and passive NOx adsorbers function based on their detailed atomic structure that dictates their chemical behavior in exhaust conditions. The changes in exhaust conditions, including hydrocarbon species and/or contaminants, must be carefully considered in aftertreatment technology design. The capability enables understanding of how the change in exhaust conditions when using bio-derived blendstocks is affected by atomic. |
Limitations | Typical advanced surface science techniques require the study of carefully designed model catalysts versus fully-formulated vendor-supplied catalysts. |
