Institute for Interfacial Catalysis (IIC)
Catalyst materials and technologies are vital to current and future efforts to 1) reduce our need for imported energy resources by developing new energy production processes and better methods for using domestic resources; 2) develop new energy-efficient and environmentally benign chemical production processes; and 3) develop new emission reduction technologies. A grand challenge of chemistry, and focus of the Institute, is to better understand how chemical reactions-the making and breaking of chemical bonds-are catalyzed so that reactions can be controlled to make desired molecules at practical, meaningful rates.
The Institute was established to build and deploy, for the benefit of the research community, new capabilities, particularly tools addressing single site and operando catalysis, that take advantage of revolutionary advances in nanotechnology and high-performance computing. PNNL's strong catalysis portfolio serves as the foundation for IIC's interactions and collaborations with fundamental and applied scientists across the Nation and around the globe.
Fuel Research
Fuel Efficient Diesel Particulate Filter ( DPF) Modeling and Development
This project will develop and optimize models that accurately predict the soot build up characteristics in advanced diesel particulate filters (DPFs) so that diesel engine-particulate filter interactions can be optimized to improve fuel efficiency. The model will utilize lattice Boltzmann (LB) modeling and testing techniques unique to Battelle, management and operations contractor of the Pacific Northwest National Laboratory (PNNL), to document the substrate characteristics that have a significant effect on fuel efficiency. Also, the LB model will investigate substrate characteristics to enhanced performance of catalytic coatings, e.g., NOx absorbents, to improve fuel efficiency while maintaining or improving performance. This project will have broad application to various substrates to improve fuel efficiency of DPF systems.
