LECO GCxGC Technology Used in Award-Winning Paper
19 Jul 2013

The American Chemical Society (ACS) recently honored Researchers at Worcester Polytechnic Institute, Massachusetts Institute of Technology, and Woods Hole Oceanographic Institute with the prestigious R.A. Glenn Award, which signifies the most innovative and interesting technical paper presented at the Fuel Chemistry Division of the 2013 ACS National Meeting. The award is based on the oral presentation, technical excellence, and the quality of the preprint, and is named in honor of Richard A. Glenn, who served as Assistant Director of Research at Bituminous Coal Research, Inc., and as Chairman of the Fuel Chemistry Division in 1960.

The award is for the technical paper “Sulfur Group Type Response to an Oxidative Desulfurization Treatment,” which utilized two-dimensional gas chromatography (GCxGC) from LECO and sulfur selective detection to identify that oxidation of sulfides/disulfides/thiophenes and benzothiophenes, the two common sulfur group types in military jet fuels, can be greater than 95% for high sulfur feeds (1400 ppmw). The paper’s authors are Michael Timko of the Department of Chemical Engineering at Worcester Polytechnic Institute (lead author); Ezequial Schmois, Pushkaraj Patwardhan, Yulko Kida, Caleb Class, and William Green of the Department of Chemical Engineering at Massachusetts Institute of Technology; and Robert Nelson and Christopher Reddy of the Department of Marine Chemistry and Geochemistry at Woods Hole Oceanographic Institute.

“We used a LECO GCxGC-TOFMS and a LECO GCxGC-modified with a sulfur detector in order to find and identify sulfur-containing species created during a unique and novel oxidative desulfurization of jet fuel,” said Robert Nelson. “The goal of this project is to reduce the concentration of sulfur-containing species in jet fuel, which in turn results in lower concentrations of sulfur species in the atmosphere and creates less acid rain.”

The Division of Fuel Chemistry will present the award at the Fall ACS National Meeting in Indianapolis in September. Look for more information in the coming months.
