Access Period: 30 days
Duration: 8 Hours
This four session course will explore the main elements of the catalytic converter: the catalyst, the honeycomb, and the housing. Session One will cover catalyst fundamentals to equip participants with the basic concepts, important design parameters and main elements of the catalyst, the washcoat and the unitary support. The second session will add discussion on catalyst durability and the effects of in-use on the maintenance of catalyst performance. The third and fourth sessions will explore the ceramic honeycomb as an integral part of emissions control device.
Catalytic emission controls is a key design element of all commercial engines today, whether for autos, trucks, small engines or lawnmowers. Stringent emissions legislation and the advent of low-sulfur fuels have led to new developments to meet the 120,000 vehicle mile durability for passenger cars and 300,000 vehicle mile durability for trucks and buses. Catalytic converter design has become a high priority issue with the new more stringent regulations worldwide.The instructors recommend their book with Robert Farrauto, Catalyic Air Pollution Control: Commerical Technology, 3rd Edition, as a supplement to the course content.
Is this Web Seminar RePlay for You?
This course will be especially valuable for engineers and others involved in the design, operation and calibration of an emission control system for both mobile and stationary source applications. This includes automobiles, trucks, buses, ships, locomotives, stationary engines, small engines, etc. Participants will be equipped to be conversant in catalysis, the key elements, acronyms, preparation on honeycomb supports, key accelerating aging tests, key performance tests, key issues with in-use, important design parameters and the questions to ask of catalyst suppliers to assist in meeting future emission regulations for all powerplants.
This course is designed for mechanical, metallurgical and chemical engineers, materials scientists, and chemists involved in heterogeneous catalysis, who are interested in handling, assembling, and failure analysis of catalytic converters. Participants should have a basic familiarity with automotive emissions for gasoline engines, diesel engines or off-road applications will prove valuable for participants.
This course is designed to cover the entire breath of education and experience backgrounds. For instance, it would help the newly hired engineer working in catalytic emissions controls as well as the seasoned veteran who just transferred to the emission control group.
