SUMMARY:CHE 598 Seminar: PNNL’s Vehicle Engine Exhaust Research – Past, Present, and Future Impact
LOCATION:Center for Undergraduate Education (CUE), NE Troy Lane, Pullman, WA 99164
DESCRIPTION:SPEAKER: Kenneth Rappe, Chief Engineer, Energy Processes & Materials Division, Pacific Northwest National Laboratory\n\nBIOGRAPHY:\n\nMr. Ken Rappe is a Chief Engineer in the Energy Processes & Materials Division at Pacific Northwest National Laboratory (PNNL). He received his B.S. and M.S. degrees in Chemical Engineering from Washington State University in Pullman before joining PNNL in 1996. Mr. Rappe currently serves as Team Lead for the Applied Catalysis Team in PNNL’s Advanced Energy Systems Group. He is also the Project Manager for PNNL’s ~$2M engine exhaust aftertreatment research portfolio in support of the Off-Road, Rail, Marine, and Aviation (ORMA) program within DOE’s Vehicle Technologies Office (VTO). For his research in support of DOE-VTO, Mr. Rappe is the recipient of a Federal Laboratory Consortium (FLC) award for excellence in technology transfer to industry, a USCAR (United States Council for Automotive Research) Team Award, and a Distinguished Achievement Award from DOE-VTO. Mr. Rappe’s research at PNNL has also included advanced carbon dioxide sorbent and sorbent systems development in collaboration with the U.S. Navy and the Naval Surface Warfare Center, for which he has received an R&D100 Award, an ACS Team Chemistry Award, and an FLC Award.\n\n \n\nABSTRACT:\n\nSince the first car emissions standards enacted by the 1977 Clean Air Act Amendment that, at the time, regulated CO and hydrocarbon (HC) emissions from new cars starting in 1981, engine exhaust aftertreatment has been ubiquitous to the internal combustion engine. Vehicle engine exhaust aftertreatment catalysts represent one of the greatest human technological successes of the past ½ century. Today the requirements for engine exhaust catalysts have become highly challenging as U.S. EPA regulations for engine emissions have tightened, required full-use-life of aftertreatment catalysts have increased, key materials have become much more expensive, and engine advancements have improved at converting fuel into engine work. This presentation will provide a brief summary of PNNL’s historic impact on aftertreatment catalyst research and development. An overview of PNNL’s current aftertreatment research and focus areas will be presented, including the role of key collaborations with engine and vehicle manufacturers, catalyst suppliers, and academia. And finally, the future of PNNL’s impact in exhaust aftertreatment will be presented with a focus on critical materials usage and domestic energy security.\n\n
