Fundamental Emission Catalysis Capabilities

Capability Title Fundamental emission catalysis capabilities
Laboratory Pacific Northwest National Laboratory (PNNL)
Capability experts Fan Lin, Kenneth Rappe, Yong Wang
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.
Unique aspects
  • Advanced and one-of-a-kind NMR and EPR spectroscopic capabilities, including in-situ, to observe atomic structure and movement of key catalytic components.
  • Highly sensitive environmental TEM for metal imaging.
  • Custom designed transmission IR, DRIFTS, and isotopic IR capabilities to observed key surface reaction intermediates and their changes due to the use of bio-derived blendstock fuels.
Availability At all times, but some prioritization may be needed.
