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.- Define catalysis and identify catalyst acronyms
- Describe in-use issues
- Question catalyst suppliers
- Interpret basic test procedures for catalyst evaluation and cite key elements in catalyst design
- Define honeycomb substrate, the key properties of honeycomb structure, and the performance parameters in terms of cell dimensions
- Validate performance parameters with measured performance
- Describe test methods relevant to in-use conditions
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 will be 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.

Dr. Ron Heck is currently an independent consultant. Prior to that, Ron was a research manager responsible for developing catalyst technology for Engelhard Corporation. He has worked on the development of catalytic processes in SCR NOx, NSCR NOx, automotive catalyst, diesel catalyst, PremAirTM catalyst systems, hydrogenation technology, ozone abatement, volatile organic compound abatement, ammonia oxidation, chemical feedstock purification and chemical synthesis. Ron is a member of American Men and Women of Science and Who's Who in Technology Today. He is an SAE Fellow and a recipient of the SAE Forest R. McFarland. He was a co-instructor for courses for the SAE in automotive emission control catalysis and diesel emission control catalysis. He was a member of the Scientific Advisory Board of the Strategic Environmental R&D Program for environmental studies in the Department of Defense. Ron has been involved in over 80 publications in commercial applications of catalysts and holds 36 U.S. patents on catalytic processes. He is the co-author of the book with Dr. Farrauto entitled"Catalytic Air Pollution Control: Commercial Technology" and is the former co-editor of the NewsBrief section of Applied Catalysis B: Environmental. Ron and his former research team from Engelhard received the 2004 Thomas Alva Edison Patent Award from R&D Council of New Jersey for the invention of close coupled catalyst technology for ultra low emission gasoline vehicles. Ron received his B.S. in Chemical Engineering and his Ph.D. from the University of Maryland.
Dr. Suresh Gulati was a Research Fellow in the Science and Technology Division of Corning Inc. where he specialized in the behavior of glass, glass-ceramics and ceramics subjected to mechanical and thermal loads, their fatigue and fracture properties and their long-term reliability. He is a member of American Men and Women of Science and Who's Who in Technology Today. Dr. Gulati is the author of over 200 publications in the area of ceramic catalyst supports, fiber optics, liquid crystal display glasses, cathode ray tubes, space windows, automotive windshields, and stepper lenses made from high purity fused silica. Before joining Corning, he held positions with Cornell University, the University of Colorado, and Continental Can Company. Dr. Gulati has a Ph.D. in applied mechanics from the University of Colorado, an M.S. in mechanical engineering from Illinois Tech and a B.S. in mechanical engineering from the University of Bombay, India.
