Summary of Expertise: Listed with other top experts in: 
Expert has taught a course in air pollution control at BYU about a dozen times in the past 22 years, a course which he organized. He has general experience in the design of air pollution control systems and has specific experience in the design of catalytic converters for control of CO, hydrocarbon, and NOx pollution. He has consulted with a number of companies on design of automotive catalysts, automotive catalyst technology, and SCR catalysis.

Thirty years of expert's career has involved conducting nitrogen BET, H2 chemisorption, and TPD experiments on catalysts, coals, and coal chars. He has worked extensively in the development of standard methods for determining metal surface areas of supported metals by hydrogen adsorption. Regarded as one of the leading authorities on the characterization of catalysts by chemisorption, expert has published two critical reviews dealing with H2 chemisorption methods for base and noble metals. The BYU Catalysis Laboratory has conducted chemisorption studies for several companies to develop methods for optimizing catalyst activity and quality control.

After graduating from Stanford, expert worked for a year at Corning Inc. in automotive emissions control catalysis. There, he developed monolithic catalysts for CO oxidation and NO reduction. In the subsequent 27 years he has consulted with Corning and other companies on problems relating to automotive catalysts and catalytic converter technology. Expert is particularly experienced in the characterization and deactivation of automotive catalysts. As an invited speaker at the CRC Auto/Oil Symposium in Dearborn, he spoke on sulfur poisoning of supported metal catalysts. He has consulted with a number of companies on design of automotive catalysts and on automotive catalyst technology, Additionally, he has researched and consulted on NOx reduction catalysts for three-way catalysts and lean burn catalysts.

He has 30 years of experience characterizing supported base and noble metal, metal oxide, and metal sulfide catalysts using adsorption, spectroscopic, and activity-testing methods. He is particularly experienced with the use of Mössbauer spectroscopy, temperature-programmed desorption/reaction methods, and laboratory activity-testing methods. For over 25 years, expert has worked in the area of catalyst deactivation, regeneration, and poisoning. A number of his research projects have focused on sulfur poisoning of catalysts. He has authored or co-authored three books, more than six chapters, and several dozen articles on catalyst deactivation, carbon deposition, sintering, and poisoning. His reviews on sulfur poisoning of metals are among the most authoritative. Currently, he is preparing a book on sintering of supported metal catalysts that will be the authority on that subject. He has consulted with a number of companies on catalyst deactivation and poisoning problems.

He has directed research on the development of SCR catalysts for the past 10 years. He and his students have investigated Cu-ZSM-5 for SCR of NO with propane and Pt/Al2O3, Cu-ZSM-5, H-ZSM-5, H-Mordenite, and commercial zeolite catalysts for SCR of NO with ammonia. The most recent work in his lab focused on the kinetics and mechanism of SCR of NO with ammonia on H-ZSM-5 and H-Mordenite. The results of this work appeared in late 1997 (vol. 171) in the Journal of Catalysis. The mechanistic information in this study has led to the development of a new process concept for relatively low-temperature SCR of NO with ammonia over H-Mordenite. He has consulted with several companies on the development of SCR catalysts.

He has conducted research over the past 20 years on cobalt and iron catalysts used in 2nd and 3rd generation Fischer-Tropsch processes. His research has emphasized activity/structure relationships; catalyst characterization by adsorption methods and Mossbauer spectroscopy; every aspect of catalyst deactivation; and kinetic/mechanistic studies. He is a recognized authority on cobalt catalysts for Fischer-Tropsch synthesis. Over the past 10 years he has consulted with several companies (large and small) on activity testing, catalysts characterization, and deactivation problems in FTS. He is very knowledgeable regarding gas-to-liquids (GTL) technology.

He directed several research projects dealing with the characterization of Mo catalysts for CO hydrogenation and hydrotreating. He also spent a summer working at Unocal on hydrotreating catalysts. More recently he reviewed deactivation of hydrotreating catalysts in a chapter in a book edited by Oballa an Shih. His new book Fundamentals of Industrial Catalytic Processes contains a chapter on petroleum refining that was in large part written by him, including a large section on hydrotreating. The book also treats the modeling of deactivation of hydrotreating catalysts. He has also lectured to professionals at several companies on the modeling of catalyst deactivation in hydrotreating. conducted research on many different catalytic process during the past 30 years and has considerable experience consulting with companies on industrial catalytic processes of many different types. He has co-authored a textbook/handbook on Fundamentals of Industrial Catalytic Processes which treats in detail the chemistry, kinetics, reactor, and process design of many important catalytic processes as well as future trends in catalytic processing. From these experiences, he has developed a broad knowledge of many industrial catalytic process and an in-depth knowledge of more than a dozen different processes including CO oxidation, Fischer-Tropsch synthesis, hydrogenation, hydrotreating, selective catalytic reduction, steam-refo

Expert has conducted research for the past 30 years on preparation, characterization, and activity-testing of supported cobalt, iron, nickel, palladium, and platinum catalysts. His work has emphasized understanding the chemistry of different preparation methods; characterization by adsorption methods, FTIR, and Mossbauer spectroscopy to find activity-structure relationships; and activity testing at the laboratory scale to determine intrinsic, specific activity. His work has also focused on understanding causes of catalysts deactivation, e.g. due to carbon deposition, coking, poisoning, and sintering. He has conducted and published a number of definitive studies on the effects of dispersion and support on the properties of metal crystallite clusters.

Ph.D. dissertation involved a sophisticated Mossbauer spectroscopy study of supported Pt-Fe alloys. At BYU he used Mossbauer spectroscopy to study the chemical and magnetic properties of iron catalysts (for Fischer-Tropsch Synthesis), coal chars, coals, and air pollution particulates. BYU has state-of-the-art equipment for studying iron solids in controlled atmospheres from 77 to 773 K.

He has 25 years of experience working with reactions that produce or convert syngas to useful fuels and catalysts for these reactions. He has worked on activity testing, catalysts characterization, and catalyst deactivation of the important cobalt, iron, and nickel catalysts used in these reactions. His group has also done definitive studies of the kinetics, and modeling of methanation, Fischer-Tropsch, and steam-reforming reactions. Him and his students have conducted significant research on zeolite catalysts used in SCR of NOx for stationary power sources.

He has taught courses in chemical engineering for 27 years. His teaching expertise include (1) catalysis and kinetics , (2) chemical reaction engineering, (3)material and energy balances, (4) materials science and engineering, and (5) creativity. He has also taught short courses on (1) fundamentals of heterogeneous catalysis, (2) catalyst deactivation, (3) industrial catalytic processes, (4) Fischer-Tropsch synthesis, and (5) deactivation of hydrodesulferization catalysts.
