E.V. Murphree Award in Industrial & Engineering hemistry

Sponsored by ExxonMobil Research & Engineering Co. and ExxonMobil Chemical Co.

The work of many scientists can only be appreciated by colleagues in the same arcane specialty. The results of George R. Lester's labors, on the other hand, are familiar to hundreds of millions of people worldwide. He is considered to be one of the fathers of the catalytic converter, which destroys pollutants in automotive exhaust.

Born in War Eagle, W.Va., in 1934, Lester grew up in a coal camp. His father worked in the coal mine but was determined that his children would not follow him into the profession. Lester's opportunity to escape was provided by a tuition-free education at Berea College, where he earned a B.A. in chemistry in 1954. He continued his studies at the University of Kentucky, Lexington, earning an M.S. in 1956 and a Ph.D. two years later, both in physical chemistry.

Lester then joined Universal Oil Products as a senior research chemist. By 1974, he was manager of applied catalysis for the UOP Research Center. In 1976, he was promoted to the position of director of material science at the Signal UOP Research Center.

Eight years later, Lester returned to the lab as a research fellow with the company, which by then was called AlliedSignal Research & Technology. In this role, Good says, he studied the mechanisms by which catalysts become deactivated and designed catalysts that were less vulnerable to these processes.

He served as a senior research fellow-the company's highest technical position-from 1991 until his retirement from the firm in 1996. During the course of his career, he authored 45 patents.

Lester defied the constraints of middle age and took up flying when he turned 50. Since then he has racked up 1,300 hours of flight time, and he now pilots his own airplane.

ACS Award for Creative Research in Homogeneous or

Heterogeneous Catalysis

Sponsored by Shell Oil Foundation

Jack H.Lunsford doesn't hesitate when asked about his start in science. "I had a good friend who lived a few doors away and he had a chemistry set," Lunsford recalls. "And in those days, chemistry sets were fun," he adds chuckling. "I really enjoyed working through the experiments and just generally playing around with it."

An excellent high school chemistry teacher furthered Lunsford's interest in science. He graduated from Texas A&M University in 1957 with a bachelor's degree and from Rice University in 1962 with a Ph.D., both in chemical engineering.

Lunsford served as a first lieutenant in the Air Force from 1962 to 1965 and then joined the chemistry faculty at Sam Houston State College. In 1966, he came to Texas A&M University as an assistant professor of chemistry and moved through the academic ranks, attaining the position of professor in 1971. In 1999, he was named distinguished professor of chemistry.

Researchers in heterogeneous catalysis have long recognized Lunsford's contributions to that field. He is well known for his insightful work on zeolites, for example. Using NMR and IR spectroscopy and catalytic probe reactions, Lunsford's research group deepened understanding of the nature of acidity and catalytic sites in zeolites. And the group's work demonstrated the important role of extra framework aluminum in zeolite-supported catalytic reactions.

Lunsford, 65 and now semiretired, is perhaps best known for his contributions in the area of methane activation. The pioneering work focused on oxidative coupling of methane to form ethane and subsequently ethylene. Through research published in a number of scientific papers, Lunsford elucidated the reaction mechanism demonstrating the role of surface-formed methyl radicals.

Catalytic applications of electron spin resonance spectroscopy and related techniques is another area in which Lunsford's work is well known. He and his students devised procedures to use the spectroscopic methods for investigating paramagnetic oxygen ions such as O-, O2-, and O3- and hydrocarbon radicals involved in catalytic reactions.

Bruce C. Gates, a professor of chemical engineering and materials science at the University of California, Davis, remarks that "no one has for so long so consistently produced thoughtful, innovative, and reliable research in heterogeneous catalysis. Jack's work places catalytic chemistry squarely in the center of chemistry".

George A. Olah Award in Hydrocarbon or Petroleum Chemistry

Sponsored by the George A. Olah Endowment

Gary B. McVicker of ExxonMobil Research & Engineering Co. is being honored for his exemplary career in developing an understanding of the catalytic transformations of petroleum-derived hydrocarbons.

The vibrant nature of McVicker's work results from its being first-rate, rigorous, and well-done science. His pioneering research in the use of "smart" molecules to probe the properties of acid catalysts is accepted as definitive and has been adopted by many of his industrial and academic colleagues in their work. His early and still widely quoted papers on model compound studies of catalytic reforming of hydrocarbons clearly delineated the synergistic interaction of metal and acid sites in the bifunctional catalytic reaction pathways.

His landmark 1983 paper on isobutane conversion over both amorphous and zeolitic solid acids was the first to report that different catalytic functions are required for the initiation and propagation steps in paraffin cracking and isomerization reactions. McVicker was also among the first to identify the important role extra-framework alumina plays in promoting parafrin cracking over zeolitic solids.

In addition, McVicker, 60, has made outstanding contributions to other hydrocarbon conversion technologies. Notably, he worked on the development of platmum-iridium bimetallic reforming catalysts that were crucial to the phaseout of lead from gasoline in the U.S. His studies on staged metal and acid catalyst systems, which provided guidance for the optimization of each catalyst function, formed the basis for markedly improving the yield of high-octane motor gasoline. He continues to work on catalytic systems for producing reformulated gasoline.

McVicker is recognized as a leader in the team that developed a second-generaton Pt/KL n-hexane aromatization catalyst that exhibits a 100-fold lifetime improvement and incremental increases in both benzene yield and selectivity. McVicker recognized the need to enhance both platinum dispersion within the zeolite channels and the crystallinity and morphology of the KL zeolite support.

More recently, McVicker, has pioneered a new metal-catalyzed technology that selectively opens naphthene rings present in hydrotreated mid-distillate feed streams. The novel chemistry of this approach enhances both the yield and cetane value of the diesel fuel product without causing extensive loss in molecular weight via dealkylation of pendant ring substituents.

Born in Iowa, MeVicker received a B.S. in chemistry and mathematics from Upper Iowa University in 1963 and a Ph.D. in inorganic chemistry in 1968 from the University of Wyoming. He has been employed by ExxonMobil Research & Engineering Co. since then and is the author of nearly 50 technical papers and over 50 U.S. patents in a variety of areas. He also serves as a mentor for younger members of the technical staff and received the prestigious ExxonMobil Golden Tiger Award for such efforts.

Over the years, McVicker has received numerous other honors from his colleagues. He has served as director of the Catalysis Society of New York and is a director-at-large and vice president for the North American Catalyst Society. He received the 1995 Award for Excellence in Catalysis from the Catalyst Society of Metropolitan New Yark and the 2000 F. G. Ciapetta Lectureship Award from the North American Catalyst Society. He also serves on the editorial board of the Journal of Catalysis and chaired the 1994 Gordon Conference on Catalysis.

The award address will be presented before the Division of Petroleum Chemistry. - David Hanson

Gabor Somorjai Receives National Medal of Science

Gabor Somorjai, Professor of Chemistry at the University of California, Berkeley was among a group of 15 recipients of the US National Medal of Science. This is the highest award for science and is presented by President Bush. As Rita Colwell, director of the National Science Foundation, said in 1998 "These are superstars in their respective fields. They've contributed a lifetime of stunning discoveries. We can only recognize them once with a science medal, but we applaud them daily for their continual contributions to humankind, to the reservoir of scientific knowledge and for the impact they have on the students they mentor and educate along the way." He has also been named University Professor at Berkeley. He becomes only the 23rd individual in the entire University of California system to be honored with this prestigious title. Previous holders of this distinction include Glenn T. Seaborg and Melvin Calvin.

Israel Wachs Receives 2001 Clean Air Excellence Award

Professor Israel Wachs of Lehigh University's Chemical Engineering Department has received a 2001 Clean Air Excellence Award. The EPA 2001 Clean Air Excellence Awards program honors outstanding, innovative efforts that help to make progress in achieving cleaner air. The research, sponsored by Georgia-Pacific Corp., has provided the pulp industry with a potentially profitable and innovative third alternative method of processing their waste gases. Using a new process and catalyst developed at Lehigh, the methyl alcohol and mercaptans can be converted to formaldehyde, a building-block chemical used for the adhesives, which find application in the plywood industry. [See www.pollutionengineering.com or N. Moretti's article in Pollution Engineering, Jan. 2002, pp 24-28]. The waste gases are simply processed through a plant, which is similar in design to a conventional formaldehyde plant that utilizes commercial-grade methyl alcohol as a feed material. The novel environmentally benign process was conceptually developed and experimentally proven on a laboratory scale (see US Patent Nos. 5,907,066 and 6,198,005 Bl to I.E. Wachs/Lehigh University). The pilot plant studies were performed at Georgia-Pacific's Brunswick, GA pulp mill on the real industrial waste streams.
