He continues his work in "High Efficiency Desulfurization of Synthesis Gas," a topic he has been working with for 25 years. Hydrogen sulfide is a pollutant and its removal helps improve efficiency of the reaction. Past research has included the use of CeO to Ce2O2S for desulfination. Current research is with the Sorbent, CeO2-ZrO2 to reduce the hydrogen sulfide content to sub-ppm content. This research is supported by the Department of Energy and is being used to help meet their Vision 21 project, a super-clean power production facility. Because of his expertise in this area, he was part of the organizing committee for the 1996 NATO Advanced Studies Institute in Kuşadası, Turkey. He also took part as a lecturer and co-editor of the proceedings.
