Semih Eser is a Professor of Energy and Geo-Environmental Engineering. Eser received his B.S. (1976) and M.S. (1978) degrees in Chemical Engineering from the Middle East Technical University in Ankara, Turkey, and his Ph.D. (1986) in Fuel Science from Penn State University. From 1987 to 1988, he worked as a research associate in the Department of Chemical Engineering at Auburn University. He returned to Penn State in 1988 and was appointed as an assistant professor of Fuel Science in 1989. He served the Department of Energy and Geo-Environmental Engineering as Associate Head (2001-2006) and Acting Head (2004). At the EMS Energy Institute, Eser served as the associate director and director of the Laboratory for Hydrocarbon Process Chemistry (1995-2000). Currently, he teaches at the John and Willie Leone Family Department of Energy and Mineral Engineering and serves as the Director of Carbon Materials Program at the EMS Energy Institute. His professional activities include serving as Program Chair (2004) and Executive Committee Chair (2006), and Councilor (2010-2012) of the Fuel Chemistry Division, and Councilor (2013-2015) of the Energy and Fuels Division of American Chemical Society. He has been inducted as an ACS Fellow in 2014. Professor Eser is currently serving on the editorial boards of the Journal of ASTM International, Journal of Oil, Gas, and Coal Technology, Journal of New Carbon Materials, and as section editor of Energy and Fuels in the Chemistry Central Journal. Eser's research interests include the reactivity and microscopic characterization of cokes and carbons, coke/carbon formation and deposition mechanisms, inhibition of undesired carbon deposition, and molecular analysis and processing of petroleum feedstocks. In 2014, Professor Eser has been awarded a Fulbright Scholarship to teach at Izmir Technology Institute in Turkey.
Active research projects involve the desirable and undesirable coke/carbon formation in petroleum refining processes and internal combustion engines. Common themes and tools used in these projects include microscopic characterization of the solid carbons (polarized-light microscopy, SEM, and TEM, as necessary) along with X-ray diffraction (XRD), spectroscopic (EDX, XPS, etc.), and reactivity (temperature-programmed oxidation) analyses to understand the formation/deposition pathways. A careful synthesis of data from microscopic and spectroscopic analyses provides means of promoting desirable reactions (e.g., carbonaceous mesophase formation for manufacturing graphitizable cokes) and inhibiting undesirable reactions (e.g., solid deposition in engine fuel and lubrication systems).
